Arduino Pro Micro
The 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 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 Micro to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.
