![]() The Nano, however, runs on the ATmega328 MCU, the same chip used in the Uno. The Nano is slightly s maller than the Micro and similarly, it has been designed to fit on a solderless breadboard. This Arduino Micro Pinout is Licensed under a CC Share-Alike, Created by Alberto from Arduino Nano All in all the Micro is a great small-form-factor board for maker projects. A major difference in supplying power to the board is the Micro has done away with the DC barrel jack, so you'll be using the Vin pins or the micro-B USB connector for a Micro based project. The big difference is the physical size of the board, going from 53mm x 68mm to 18mm x 48mm.ĭirectly compared to the Leonardo and Uno, the Arduino Micro is smaller and has less power consumption, the board only uses 29mA. As it runs on the same 32u4 as the Leonardo, it has all the features of the Leonardo (which had everything the Uno did.). This tiny board is designed to fit on a solderless breadboard. This Arduino Leonardo Pinout is licensed as CC Share-Alike, Created by Alberto from Arduino Micro If you're need them, or just want to take a look you can find the datasheet for the 32u4 here. ![]() ![]() ![]() The Leonardo also uses a Micro-B USB cable for connection to your PC, which is a step away from the USB Type-B connection we see on the Uno. If you find yourself needing a couple more IO pins, USB keyboard or mouse recognition as well as all the features of an Uno, then the Leonardo may be just what your project requires. Like we mentioned above the 32u4 the Leonardo runs on, boasts its own USB support, this eliminates the need for the secondary processor chip the ATmega328 relies on for USB data transfer. 12 Analog Input Pins, 10-bit resolution on each pin.This Arduino Uno Pinout is licensed as CC Share-Alike, created by Alberto from Arduino LeonardoĪ board with built-in USB compatibility, more Analog inputs and Static RAM than the Uno? AND you can pick one up for less than the price of a standard Uno? Sounds great to us! Moving away from the ATmega328, the Leonardo features an ATmega32u4 MCU, which adds USB support to the MCU. The Uno also has optional revisions with Wi-Fi enabled, a surface-mounted ATmega328 option and a POE enabled and non-POE enabled Ethernet capable Uno. This particular board is the crowd favorite for experienced Arduino users and n00bz alike, and it's definitely the most popular of all the boards. Most SHIELDs are made for use with the Uno too, this means you get direct plug-n-play compatibility between the controller and the shield. A removable microcontroller unit means if you damage the MCU while you prototype, you can easily replace it. This board is a perfect choice for beginners. With the DC Barrel plug, you'll want to use a 9-12V 2A DC supply such as this one Powered via USB (5V 500mA) or using the Centre positive 5.5mm/2.1mm Barrel Jack connection.20mA maximum current draw per pin, 200mA maximum for ATMega328 package.All the IO pins are connectable via the 0.1" pin headers.6 Analog input Pins, a 10-bit resolution on each pin.14 Digital I/O Pins with internal pull-up resistors (disabled by default but can be enabled with input_pullup command).An ATmega328 8-bit microcontroller at the heart of the Uno provides: Now at revision 3, the Uno has everything you need to get started with maker electronics. Uno literally means one in Italian and is the entry-level Arduino board. The links below will take you to the relevant board with some really informative pinout diagrams linked with each board, if you want a tabulated specifications for easier comparison, you'll find them at the bottom of this article: Rather than telling you guys what to buy, we have put together a handy guide to show you the capabilities of each board. There are a bunch of Arduino boards, they come in different shapes and sizes, with different processing power, digital IO, and other capabilities. We'll discuss the features of each board, provide an informative pinout diagram with tonnes of detail, and toward the end of the article, provide a tabulated version of the information for quick reference. We're going to compare each of the Arduino Boards available to Maker's and Electronics Enthusiats.
