Arduino Micro with Headers - ATmega32u4 Microcontroller

The tiniest Arduino board is here! The Arduino Micro is a smaller version of the Arduino Leonardo but includes two more analog inputs and a breadboard-friendly build. It’s a perfect board for those just starting to explore the Arduino world.

The Micro is a microcontroller board based on Atmel's ATmega32u4 and has a built-in USB connection, eliminating the need for a secondary processor. This allows the Arduino Micro to appear connected as a peripheral or a virtual CDC serial/COM port. The board has 20 digital I/O pins, a 16 MHz crystal oscillator, an ICSP header and a reset button. Just connect the Micro to your computer with a micro-USB cable and you’re ready to go.
