Arduino Micro
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 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 Micro to appear to a connected computer as a mouse and keyboard,
in addition to a virtual (CDC) serial / COM port. It also has other implications for the behavior of the board;
these are detailed on the getting started page.
