• Micro, Arduino Compatible Board

If you know Arduino's you know that it is an open sourced hardware device. This means that reference files and designs are freely provided. This means that high quality boards can be made to the exact same parts, quality, functionality, and compatibility as the official released boards. This is one of those boards 100% compatible with the Arduino IDE and built with the same parts and quality.

The Arduino Micro is a microcontroller board based on the ATmega32U4 (datasheet), developed in conjunction with Adafruit. 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, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a micro USB cable to get started. It has a form factor that enables it to be easily placed on a breadboard.
The Micro board is similar to the Arduino Leonardo in that the ATmega32U4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Arduino Micro to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.
