Arduino Micro with Headers

The original Arduino Micro is a microcontroller board developed in collaboration with Adafruit and based on the ATmega32U4. It has 20 digital input/output pins, 7 of which can be used as PWM outputs and 12 as analog inputs. It also has a 16 MHz crystal oscillator, a micro USB connection, and a reset button. Everything needed to support the microcontroller is already included, so you can simply connect with a computer over a micro USB cable. It is small enough to be placed on a breadboard and similar to the Arduino Leonardo as it has integrated USB communication and appears as a mouse and keyboard as well as a virtual serial/COM port to a connected computer.
