Arduino Micro without headers

Description

Arduino Micro without headers based on the ATmega32U4, developed in collaboration with Adafruit. The same chip as the Leonardo boards, this one has a built-in USB communication. This allows the Micro to act as a keyboard and/or mouse on a connected computer.

The Arduino Micro has 20 digital input/output pins (7 of which are PWM outputs and 12 of which are 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 plug it into a computer with a micro USB cable and you're good to go. It has a form factor that allows it to be easily placed on a breadboard.
