Re: Arduino Leonardo vs Arduino Mega peteroakes Nov 16, 2014 11:22 AM ( in response to greenben214 ) The ATMEGA U16x are the ones used on most UNO boards etc to provide the USB functionalit arduino leonardo vs uno. Arduino Bazaar Getting Started Guide Product Review Arduino Leonardo Guide - Overview, and Uno Comparison . By Shawn 6 months ago . Released years ago, the Arduino Leonardo is an ATmega32U4 microcontroller board that was somehow disregarded. One of the greatest things about Arduino is the fact that the entire project is open-source. The schematics, hardware design files, and source code are all freely available for viewing and modification. Released under a Creative Commons Share Alike license, anyone is free to riff on the hardware design and produce their own version. That's how a product like the RedBoard comes to be. It still looks and acts just like an Arduino Uno, but is slightly modified to make the board better-suited to certain purposes.
Compile and upload this empty sketch to your Arduino Uno/Yun/Leonardo/Mega or Goldilocks 1284p device. This will show you how much of your flash is consumed by the FreeRTOS scheduler. As a guide the following information was compiled using Arduino v1.6.9 on Windows 10 One the most exciting feature of the Arduino Leonardo over Arduino Uno is that the ATmega32u4 of Leonardo has built-in USB communication, eliminating the need for a secondary processor. This allows the Leonardo to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port The 20 digital input/output pins can be used as an input or output. You can use the functions pinMode(), digitalWrite(), and digitalRead() to assign the pins. They operate at 5 volts. Each pin can provide or receive a maximum of 40 mA.
This board is packed full of all sorts of neat features. It can be programmed over-the-air, as long as your computer is on the same WiFi network. It's designed to easily interact with the Internet, so if your intend on making an "Internet-of-Things"-type project, the Yún may be the perfect Arduino. Arduino-programmable development boards. added to your cart ! The SparkFun Qwiic Pro Micro adds a reset button, Qwiic connector, USB-C, and castellated pads to the miniaturized Arduino bo added to your cart ! SparkFun's minimal design approach to Arduino. This is a 5V Arduino running the 16MHz bootloader. added to your cart Another solution is to prototype with a USB Native Arduino board like the Leonardo. The Arduino Leonardo uses an ATmega32U4 . A consideration before making this change however is that the ATmega32U4 microcontroller has slightly less program space and ram compared to the ATmega328P when the bootloader is installed An arduino object represents a connection to Arduino ® hardware. Use the arduino function to connect Arduino hardware to MATLAB ®. After you create the object, you can program your hardware and use custom add-on libraries directly from MATLAB using the object functions. a = arduino (port,board) a = arduino ( ___ ,Name,Value And there are more unique Leonardo-compatible boards, like the MaKey MaKey, which can turn almost anything (from tin foil to Play-Doh to bananas) into a keyboard key.
Tested digs into the key features and differences on a handful of boards, including the Arduino Uno, Leonardo, Due, Micro, LilyPad Arduino, Esplora, Yun, and Robot Arduino Mini: If you are looking to get a cheaper intro into the field, or if you need your product in a smaller size, then you may go for the Arduino mini. It has all the functionalities of the Arduino Uno in a smaller size and is cheaper than the UNO. The mini has a length of about 3cm and is hence suitable for compact projects like small robots Ambas tarjetas cuentan con 20 pines que pueden ser configurados como entradas o salidas analógicas. En la mayoría de los sitios de internet se indica que la tarjeta Arduino UNO cuenta con 14 pines digitales para ser usados como entradas o salidas, esto no incluye los seis pines indicados como entradas analógicas, los cuales pueden ser configurados, también, como entradas o salidas digitales. Esto da un total de 20 pines que pueden usarse como entradas o salidas digitales en la tarjeta Arduino UNO, al igual que en la tarjeta Leonardo. En el caso de ambas tarjetas, los pines del A0 al A5 pueden configurarse como digitales empleando la función pinMode(número de pin, modo), al colocar en el argumento correspondiente al número de pin A0 o 14, A1 o 15, A2 o 16, etc.
May 22, 2016 Arduino: Power Consumption Compared. When I first started working on my Arduino drone, I decided I wanted to evaluate, understand and compare components before selecting them.Then I would be able to come up with an optimal combination of components, or if not then at least I would understand where my design is lacking Arduino Uno is a microcontroller board based on the ATmega328P. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer. . This feature eliminates the need for a secondary processor. Thus, Leonardo appears as a mouse and keyboard to a connected computer. It also shows up as a virtual (CDC) serial / COM port.
The Yún has built-in Ethernet and Wi-Fi support, a USB-A port, a microSD card slot, 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, microUSB connection, an ICSP header and 3 reset buttons. The Yún is also capable of communicating with the Linux distribution onboard, offering a powerful networked computer with the ease of Arduino. Arduino Hole Dimensions Drawing Arduinos are great, but if you've ever tried to mount one on a baseplate or inside an enclosure, you know it can be a pain. While there are some great enclosures specifically designed for an Arduino, if you just have a regular box that you want to use, you have to measure and mark out the holes yourself The Arduino software includes a serial monitor. This feature allows you to send simple textual data to and from the Arduino board. The RX and TX LEDs flashes when data is being transmitted via the USB connection to the computer. But, this feature is not active when serial communication occur on pins 0 and 1. Arduino UNO (at 16mhz, 5v) 3. Calculating the Arduino Power Consumption. Using the formula Power = Voltage x Current. Power = 5v * 46.5mA = 232.5mW . 4. Let's put Arduino put to SLEEP. Let's take the same Arduino UNO and run the sleep code. The code I have wake up every few seconds upon Watchdog timer timeout and toggle the onboard L LED The Arduino Uno can come with a WiFi module integrated into the board. Online, users have shown that Bluetooth could be added to both the Mega and the Leonardo. Conclusion. Both the Arduino Uno and Arduino Mega are excellent micro-controller boards. In fact, they mirror each other. The Mega is the grown-up version of the Uno
The Arduino Leonardo is a microcontroller board based on the ATmega32u4 ().It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button .The O.G. LilyPad is the LilyPad Arduino. This is basically a purple Arduino Pro 3.3V/8MHz. All of the pins -- 14 digital and six analog -- are arranged around the outer edge of the board. There are also inputs for power at the '+' and '-' pins.
A permanently attached battery on the SimpleSnap also sets it far apart from other LilyPad boards. Just flick the switch to "ON" and the board should start running its sketch. To charge the battery, plug an FTDI Basic into the SimpleSnap. Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments The Arduino Robot is the very first official Arduino on wheels. The robot is equipped with two processors — one for each of its two boards.Flash Space: This is the amount of program memory that the chip has available for your to store your sketch. Not all of this memory is available as a very small portion is taken up by the bootloader (usually between 0.5 and 2KB).Tipo de cable para conectar a la computadora Otra de las diferencias que es importante tomar en cuenta cuando se va a adquirir una tarjeta UNO o Leonardo es el cable USB que se requiere para conectarlas a la computadora. En el caso de la tarjeta UNO se requiere un cable A – B, como el que utilizan la mayoría de las impresoras actualmente. La tarjeta Leonardo requiere un cable A – micro B, como el que se utiliza para la mayoría de los celulares actualmente.
This table shows a quick comparison between the characteristics of all the Arduino and Genuino boards. I'm new to Arduino, this may be a dumb question but can I use a keyboard to be the main input like a series of buttons but only using a USB/PS2 connection, which will use fewer input pins? I know Arduino Leonardo can emulate a keyboard, but can I use a keyboard as an input to the Arduino? Is it possible Adafruit Industries, Unique & fun DIY electronics and kits Adafruit Motor/Stepper/Servo Shield for Arduino v2 Kit [v2.3] ID: 1438 - The original Adafruit Motorshield kit is one of our most beloved kits, which is why we decided to make something even better. We have upgraded the shield kit to make the bestest, easiest way to drive DC and Stepper motors
To make use of the debug capabilities, you need to move outside of the Arduino IDE and into Atmel Studio. Conclusion. If in doubt about the difference between programming and native ports, use the programming port. Keep in mind if you are used to the Uno or other 8-bit Arduino boards, the 32-bit Due and Zero are completely different The Arduino boards on this page all feature the ATmega328 as their main MCU brain. The microcontroller alone makes every board on this page nearly identical in terms of I/O count and memory. Their differences stem from things like programming interfaces, form factors, and operating voltages.Comunicación SPI Otro protocolo de comunicación empleado por las tarjetas UNO y Leonardo es el SPI. Esta abreviatura se refiere a la expresión en inglés Serial Peripheral Interface, que puede traducirse como Interfaz Serial Periférica. La comunicación serial con este protocolo se realiza, en la Tarjeta UNO, por los pines 10, 11, 12, 13, empleados para las líneas SS, MOSI, MISO, SCK, respectivamente. En cuanto a la tarjeta Leonardo, los pines destinados para comunicación SPI se encuentran en el conector ICSP, que es el conector macho de seis pines ubicado cerca de uno de los extremos de la tarjeta. Si se emplea un Shield que utilice este protocolo de comunicación y dicho Shield no cuenta con un conector de seis pines para ICSP, el Shield no funcionará.The RX and TX LEDs on the board will flash when data is being transmitted via the USB-to-serial chip and USB connection to the computer (but not for serial communication on pins 0 and 1).
LilyPads are great for e-texitles -- projects which combine electronics and fabric wizardy. They can be used to make nifty talking aprons, dice gauntlets, or more simple trinkets like light-up firefly jars. Arduino's use Atmega16U2 (Uno & Mega) or FT232 (Nano) for USB/Serial, while $2 clones use CH340g for that purpose. I use FT232 or FT232 modules in my designs as the US distributors do not carry CH340g chips, and I won't design in parts I cannot source from reputable suppliers For Arduino Leonardo, the pins on the ICSP header are not connected to any of the digital I/O pins as they are on the Uno. They are only available on the ICSP connector. This means that if you have a shield that uses SPI, but does NOT have a 6-pin ICSP connector that connects to the Leonardo's 6-pin ICSP header, the shield will not work The smaller form factor and absence of connectors means this board can be more custom-tailored to fit into a project. You can solder wires or connectors directly onto the pins you need. Then again, it has the same pin footprint as the Uno, so it's still shield compatible. 5. Difference between Arduino Leonardo and Arduino Uno. There is a slight difference between these two boards in terms of controller used, number of digital pins, PWM pins, and the pins reserved for SPI communication. Arduino Uno incorporates ATmega328 while Arduino Leonardo comes with ATmega32U4
In order to complete a project, you must know what components are needed to get the job done. If you new to electronics and want to learn the basics, the Uno is the board for you. Sensor Data - The Arduino really took off because it has analog-to-digital input, in other words, you can take in sensor data like light, temperature, sound, or whatever using the low-cost sensors already on the market and get that into the Arduino easily. It also has ready-to-go SPI and I2C for digital sensors. This covers 99% of sensors on the market The Arduino Leonardo is a microcontroller board based on the ATmega32U4. It has 23 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power.
This seems to be a trend, doesn't it? If you're looking for a stripped-down version of the Mega -- no USB-to-serial converter, no connectors -- there's the Mega Pro 5V and 3.3V/8MHz variants.What better time than Arduino Day to take a closer look at the company’s extensive lineup of Atmel powered devices for your next project?The board is equipped 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, microUSB connection, a ICSP header and a reset button. The Micro includes everything needed to support the microcontroller; simply connect it to a computer with a microUSB cable to get started. The Micro even has a form factor that lets the device be easily placed on a breadboard.Let's face it, there are a a lot of different Arduino boards out there. How do you decide which one you need for your project? In this tutorial, we'll take a look at the diverse world of Arduino boards. We'll begin with a tabular overview of the features each board has. Then we'll delve deeper into each board, examining the pros, cons, and example use-cases.The board also has six analog inputs, a 16 MHz quartz crystal, USB connection, power jack, ISCP header and a reset button.
Originally based on the ATmega168, and now equipped with the ATmega328, the Arduino Miniis intended for use on breadboards and projects where space is at a premium.. It is a high performance, low-power AVR RISC-based 8-bit micro-controller.
Arduino Board Size & Pricing Comparison . The Micro comes in, being true to its name, at 0.7 x 1.9 making it one of the smallest microcontroller boards out there. On the opposite side of the spectrum, the Arduino Mega 2560 board dimensions are about 4 x 2.1, making it about 6x bigger than the Micro in terms of area size. Arduino Uno dimensions of 2.7 x 2.1 fall somewhere in. Using the SmartThings Arduino Shield (ThingShield), you can add SmartThings capability to any Arduino compatible board with the R3 pinout, including the Uno, Mega, Duemilanove, and Leonardo Since Leonardo has USB support onboard it doesn't require an external microcontroller for USB connection. Whereas the UNO requires an additional microcontroller to provide the USB capability.You thought the Mega was powerful? The Arduino Due is a revolutionary take on the Arduino platform. It sports an entirely different processor architecture -- ARM instead of AVR. It's a 32-bit processor, clocks in at 84 MHz, and has native USB support. Arduino Uno compatible, D13 pin isolated with a MOSFET of which can also be used as an input. KitTen Stock Arduino Leonardo with a built-in BLE (Bluetooth Low Energy) 4.0. Development environment is MS Visual Studio and C#. Pin compatible with Arduino shields although drivers are required for some shields
PWM: This is the number of digital I/O pins that are capable of producing a Pulse-width modulation. (PWM) signal. A PWM signal is like an analog output; it allows your Arduino to "fake" an analog voltage between zero and the system voltage.. Check them out!
The Arduino AtHeart program was specifically launched for Makers and companies with products based on the open-source board that would like to be clearly identified as supporters of the versatile platform. The program is available for any device that includes a processor that is currently supported by the Arduino IDE, including the following Atmel MCUs: Arduino UNO. The UNO is arguably the most popular Arduino. It is powered by an Atmega328 processor operating at 16MHz, includes 32KB of program memory, 1KB of EEPROM, 2KB of RAM, has 14 digital I/O, 6 analog inputs, and both 5V and 3.3V power rails Teensy vs. Arduino. Before we go into the major differences, let's take just a second to understand the Arduino and what makes it important. Also, if you decide to purchase one of these units, here's a handy parts list: Arduino Uno or Arduino Nano; Teensy 3.6; Breadboard and Wires; The Arduino. So let's get into this The LilyPad Arduino SimpleSnap is an offshoot of the Simple. The layout is the same, the battery-charging functionality is still there, but instead of an array of petals around the board there are snaps.
You can press the upload button on the interface toolbar to activate this feature in the Arduino Software (IDE). Then, the bootloader will have a shorter timeout. This action allows the coordination of lowering the DTR the start of the upload.Just as the Pro Mini took the guts of the Arduino Uno and shrunk them down, the Pro Micro works as a miniature version of the Leonardo. Unlike the Pro Mini, the Pro Micro doesn't require an external board to upload a sketch -- the 32U4 takes care of everything! Arduino Leonardo For this project we are using the Arduino Leonardo, it is a microcontroller board based on the ATmega32u4. It has 20 digital input/output pins (out of which 7 can be used as PWM outputs and 12 as Analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header and a reset button
Arduino UNO (R3) LilyPad Arduino; Red Board; Arduino Mega (R3) Arduino Leonardo; Arduino UNO (R3) The Arduino UNO R3 is a new board and by comparing with the previous Arduino boards it has some additional features. The Arduino UNO uses the Atmega16U2 instead of 8U2 and it allows faster transfer rate & more memory Arduino Leonardo. The Arduino Leonardo is built around the versatile ATmega32U4. This board offers 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, microUSB connection, power jack, an ICSP header and a reset button True to its name, the LilyPad Arduino Simple is an easier-to-use version of the standard LilyPad Arduino. Fewer pins are broken out -- nine digital and four analog -- but the LilyPad Simple has some added functionality too. This board is designed specifically to be powered by a Lithium Polymer battery. There's an on-board JST connector for the battery to plug into, and there's even a special circuit dedicated to charging the battery.
So, go for Leonardo as it is low cost. Then you can harness the USB capability of Leonardo if you want. Step 2: Program the Arduino. On the Arduino there is a built-in LED (digital pin 13). This pin is placed different on the UNO and Leonardo, see picture above. In this tutorial we will make this light up when the Arduino receives a wirelessly signal. Place one of the XBee's on the shield and place the shield on the Arduino As Majenko wrote: the Arduino Yún = Leonardo + Yún shield. You get into a lot of trouble with the Arduino Uno, and the Yún shield has already enough troubles on its own. Maybe the Arduino Mega 2560 can be used when both the hardware and software is changed to use another hardware serial port for the Yún shield
Entradas analógicas y salidas de PW Otras de las diferencias que surgen como consecuencia del microcontrolador en el que están basadas las dos tarjetas es la cantidad de pines que pueden ser configurados como entradas analógicas y salidas de PWM. La tarjeta Arduino UNO cuenta con 6 canales de entrada analógica, en los pines del A0 al A5. La tarjeta Arduino Leonardo cuenta con 12 canales de entrada analógica, los pines del A0 al A5, y los pines 4, 6, 8, 9, 10 y 12, que corresponden a los canales del A6 al A11. La tarjeta Arduino Leonardo cuenta con una salida de PWM mas que la tarjeta UNO, ubicada en el pin 13. El resto de las salidas de PWM se ubican en los mismos pines en ambas tarjetas. Estos pines son el 3, 5, 6, 9, 10 y 11.The Mini boards pack all of the remaining punch of the Arduino Pro into a much smaller footprint. Every pin is still broken out (actually, more pins are broken out), they're just in a very different footprint. The Raspberry Pi vs. Arduino Summary. In summary, the Arduino is more suited for projects that require interaction with devices and sensors. It's a great way to learn the basics of programming and interacting with devices, sensors and other real-world objects. Buy The Arduino Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments. Or more simply, you load on some code and it can read sensors, perform actions based on inputs from buttons, control motors, and accept shields to further expand it's capabilities. Really, you can do almost anything.This popular board — based on the ATmega328 MCU — features 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, USB connection, power jack, an ICSP header and a reset button.
These snaps can be plugged into the mating snaps on a SimpleSnap ProtoBoard, or any size 1/0 snap already sewn into a fabric.The brain of the Mega is an ATmega2560, a fully souped up ATmega328. Aside from the massive processor overhaul, the Mega still shares a lot in common with the Arduino Uno. There's a secondary IC on-board (an ATmega16U2) to convert USB-to-serial to allow USB programming. It runs at the same speed -- 16 MHz. All of the pins are broken out in a way that keeps the board shield-compatible. Because of these similarities, the Mega is a good option for Arduino beginners and experts alike. LoRa Shield is a long range transceiver on a Arduino shield form factor and based on Open source library.The Shield allows the user to send data and reach extremely long ranges at low data-rates.It provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption.. LoRa Shield is based on Semtech SX1276/SX1278 chip, it targets. This Board is recommended for beginners and experts alike. As long as you're OK with having less I/O pins, the extra functionality of the Simple makes it well worth it.
The Yún combines an ATmega32U4 (the same MCU on Leonardos) and an embedded Linux machine running the OpenWRT Linux OS. The two processors are "bridged" together. You program the ATmega32U4, just like you program an Arduino Leonardo, over USB. The 32U4 can send commands to the Linux processor, just as you might send commands to your Linux computer in a terminal. The Arduino does not have a built-in digital-to-analog converter (DAC), but it can pulse-width modulate (PWM) a digital signal to achieve some of the functions of an analog output. The function used to output a PWM signal is analogWrite (pin, value). pin is the pin number used for the PWM output. value is a number proportional to the duty cycle.
Arduino Uno vs Leonardo-difference between Arduino Uno and Leonardo. This page compares Arduino Uno vs Leonardo and mentions tabular difference between Arduino Uno and Leonardo.. Following table mentions comparison between Arduino Uno and Leonardo Have you picked the perfect Arduino for your project? Looking for more Arduino tutorials? Check these out:The boards above -- all with an ATmega328 as the brain -- all require an external FTDI Basic to have code uploaded to them. The LilyPad Arduino USB -- which uses an ATmega32U4 -- has all of the USB functionality on-board. It has a micro-B USB connector, so you just plug the cable in, attach it to your computer, and program away!Programming Interface: This is how you hook up the Arduino board to your computer for programming. Some boards have a USB jack on-board so that all you need to do is plug them into a USB cable. Others have a header available so that you can plug in an FTDI Basic breakout or FTDI Cable. Other boards, like the Mini, break out the serial pins for programming but aren't pin-compatible with the FTDI header. Any Arduino board that has a USB jack on-board also has some other hardware that enables the serial to USB conversion. Some boards, however, don't need additional hardware because their microcontrollers have built-in support for USB. Arduino Leonardo; Arduino Uno (I have only tested with uno) If not in the list, the macro will revert back to digitalWrite(), pinMode() or digitalRead() Installation. Download the repo as zip, extract and place into Arduino IDE libraries folder. Rename digitalWriteFast-master to digitalWriteFast Arduino IDE does not accept dash character.
You can also power the board using a AC-to-DC adapter or connect it to a battery source. If for some reason you do something wrong, the computer chip is easily replaced.The Leonardo is designed to allow software from a connect computer to reset it. This feature eliminates the need to physically press the reset button prior to an upload.
You are in your first semester of engineering school. Your instructor introduces the subject of electronics to the class. She does a good job explain the topic, but you want to get some hands-on training to re-enforce the discussion. Where do you start? Arduino Bootloader Burn Using USBASP. by Nikodem Bartnik April 3, 2020. Replacing the microcontroller is possible on the Arduino Uno only, since you can easily take it off the board and replace it with a new one. This is not possible with the Arduino Leonardo because the microcontroller is soldered to the board. Parts needed
Arduino Uno Pinout Guide. In our last two posts, we focused on the software aspects of the Arduino. We saw that Arduino boards are programmed using a language derived from C and C++ in Arduino's Integrated Development Environment (IDE) and learned a few basic debugging methods.In this post, we'll be taking a closer look at the Arduino hardware, and more specifically, the Arduino Uno pinout RoMeo V2 [R3] is an All-in-One Arduino based robot board, it is especially designed for robotics applications, and extended devices. Romeo benefits from the Arduino open source platform, it is supported by thousands of open source projects, and can easily be expanded with Arduino Shields.The integrated 2 way DC motor driver and Xbee socket allows you to start your project immediatly without. In this article, I'll talk about the Arduino Uno R3 only. It's the most used in the world and the most similar to the Raspberry Pi in term of size and disposition. But you could also check other devices from the same company: Basic devices (Uno, Leonardo, 101 or Esplora
If a sketch running receives one-time configuration or any other data during start-up, ensure that the software that is communicating with the board delays a second after opening the connection and before sending its data. The Arduino Leonardo is awesome. The newest dev from the Arduino team features USB functionality (read: stream Arduino data directly into any windows/mac app!), more pin power (more PWM, more I/O.
Obviously, these boards aren't shield-compatible, but they are breadboard-compatible. You can solder male headers into the Pros, and straddle it across the breadboard's middle strip. The small form-factor also makes them very conducive to embedding into projects (like in the H2O pH Probe).I found that they sell UNO Starter kits and Leonardo Starter kits. There are many different products. My eyes are so busy. I am a greenhand. If I want to buy a stater kit, which one should I buy? UNO or Leonardo? Read about 'The Things Uno based on the Arduino Leonardo with an added Microchip LoRaWAN module' on element14.com. The Things Uno use a long range and low power radio frequency protocol called LoRaWAN and for short range Bluetooth 4.2. The technology allows for thing Arduino Leonardo. The Leonardo is the patriarch of all ATmega32U4 Arduino boards. It shares the same form factor and I/O placement (analog, PWM, I 2 C pins in the same place) as the Arduino Uno, so it remains shield compatible
The winner is the Arduino Uno. The Uno provides enough functionality to get a novice on his/her way to learning electronics and conducting less complicated projects. Trying to decide: Leonardo vs Micro? Aside from being able to use shields and a standard wall wart are there any other benefits from using a Leonardo over a Micro? Looking at their pages at Arduino.cc they look like you get access to the same number of pins
The Arduino board exposes most of the microcontroller's I/O pins for use by other circuits. The Diecimila, Duemilanove, and current Uno provide 14 digital I/O pins, six of which can produce pulse-width modulated signals, and six analog inputs, which can also be used as six digital I/O pins. These pins are on the top of the board, via female 0.1-inch (2.54 mm) headers The board is part of the world’s leading open-system hardware and software ecosystem. The company offers a wide range of software tools, hardware platforms and documentation to allow you to use technology in creative ways.‡The LilyPad Simple Board does have one UART but the pins aren't broken out to pads. Serial communication can be achieved through the FTDI header.The board is based on the ATmega168V (the low-power version of the ATmega168) or the ATmega328V. The LilyPad Arduino was designed and developed by Leah Buechley and SparkFun Electronics. Readers may also want to check out the LilyPad Simple, LilyPad USB and the LilyPad SimpleSnap.The Pros come in two varieties: 5V/16MHz and 3.3V/8MHz. The 5V/16MHz board runs at the same voltage and speed as the Arduino Uno. The 3.3V/8MHz board is unique, though, because it can operate at a lower voltage. A lower operating voltage makes the board easier to power with batteries (LiPos specifically), but it also means the clock speed has to be turned down. The 3.3V/8MHz board runs at half the speed a regular Arduino Uno...but 8MHz is still pretty darn fast for many applications. You can still turn an LED on and off more than a million times per second!
Arduino Uno vs. Leonardo with HumanHardDrive Learn the differences between the Arduino Uno and the Arduino Leonardo as Human Hard Drive reviews each board's processors, connectors, pins, and USB protocols The latest version of the Arduino Uno i.e. Uno Rev. 3 has an Atmega 16U2 programmed as a USB to serial converter instead of the FTDI USB to serial driver chip. Another point worth mentioning is that the ATmega32u4 of the Leonardo is SMD packaged, while the Atmega 328 of the Uno is DIP, meaning one can actually take out the IC from Uno and use.

Leonardo is much younger than Uno, that's why you hear more about Leo. The blog also mentions a few nice Leonardo features:
Arduino Uno communicates with other devices (a computer, another Arduino board, or other micro-controllers) through numerous communication facilities. Available on digital pins 0 (RX) and 1 (TX), the ATmega328 provides UART TTL (5V) serial communication.This article will compare two of the most popular micro-controller boards in the world: Arduino Mega and Uno. Base on the analysis, I will recommend which board best suits the needs of a beginner.
For a beginner, the Uno might be a better choice, except if you either know you’re not planning to buy shields, or if you have plans for fancy USB projects. Input Voltage: This is the suggested input voltage range for the board. The board may be rated for a slightly higher maximum voltage, but this is the safe operating range. A handy thing to keep in mind is that many of the Li-Po batteries that we carry are 3.7V, meaning that any board with an input voltage including 3.7V can be powered directly from one of our Li-Po battery packs.From an practical and average Arduino user perspective the pin functionality will be the same. For the nitty gritty details refer to the datasheet ATmega32u4 for Leonardo and ATmega328 for UNOAs the first Arduino built on a 32-bit ARM core microcontroller, Due boasts 54 digital input/output pins (of which 12 can be used as PWM outputs), 12 analog inputs, 4 UARTs (hardware serial ports), an 84 MHz clock, USB OTG capable connection, 2 DAC (digital to analog), 2 TWI, a power jack, an SPI header, a JTAG header, a reset button and an erase button. The Arduino Uno and Arduino Uno revision 2 both have a LED and resistor connected in series on Arduino pin 13. The revision 3 board buffers this LED/resistor through a unity gain op-amp. This is the spare op-amp that was unused on previous boards
Raspberry Pi and Arduino are quite different boards. Each board has its own advantages and disadvantages. If you want to decide between the two, then it depends on the requirement of your project. Let understand these two boards in detail. Arduino was invented by Massimo Benzi in Italy. Arduino was a simple hardware prototyping tool. [ Connect your Arduino using the USB cable. The square end of the USB cable connects to your Arduino and the flat end connects to a USB port on your computer. Choose Tools→Board→Arduino Uno to find your board in the Arduino menu. You can also find all boards through this menu, such as the Arduino MEGA 2560 and Arduino Leonardo The SainSmart Leonardo R3 is a microcontroller development board based on the ATmega32U4.
