Idea

Arduino Micro with Headers

The Arduino micro is a microcontroller board based on the atmega32u4, developed in conjunction with adafruit. It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analogue 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.
