Arduino Buyers Guide #

Introduction #

This is a guide on all the different Arduinos available to help you choose the right board for your project.

Popular Arduino Boards #

Arduino Uno #

The Arduino Uno is the most common Arduino because it has a normal amount of I/O. Also, there is no need to solder.

Arduino Leonardo #

The Leonardo has the same form-factor as the Uno but can be used as an HID device, like a gamepad or "button box" and such.

Arduino Mega 2560 #

The Mega 2560 is extremely common. It has over three times I/O than the Uno. If you need a lot of LEDs, or pins to use, the Mega is a good choice for this.

Arduino Due #

The Due also has a lot of I/O, has more memory than the Mega 2560 which also makes it a great starter board.

Arduino Micro #

The Micro is good to use on a breadboard. It's also compact and has the same chip as the Leonardo.

Arduino Nano #

The Nano has the same chip as the Uno so can be used in a final product. Many times it's easiest to prototype on an Uno, then when all the debugging is done, use the Nano for the final product.

Arduino Zero #

The Zero uses 3.3V instead of the normal 5V. Also it is a 32-bit board so it can process a lot faster.
