Micro

The Arduino Micro packs all of the power of the Arduino Leonardo in a 1.9” x 0.7” (48mm x 18mm) size.

You can program it directly via the USB micro connector on one end (or for the advanced users, the 6-pin ISP header).

The Arduino Micro is a microcontroller board based on the ATmega32u4 ( datasheet ), developed in conjunction with Arduino.

Onboard is the processor, crystal, micro USB connection with fuse, Reset button, ISP low-level reprogramming header, ON LED, TX and RX LEDs, a extra user pin #13 LED, and a 3.3V regulator.

This version of the Micro comes with headers pre-soldered on and runs at 5V logic with a 16MHz crystal.

This version of the Micro comes without headers pre-soldered on.

It’s the cutest, tiniest little Arduino yet!

You’ll probably also want to pick up a micro-B USB cable to connect this board to your computer You can use it for basic Arduino sketches as well as USB client projects like making it appear as a mouse or keyboard to your computer!
