It's, again, the cutest and the smallest Arduino! The Arduino Micro embeds all the power of an Arduino Leonardo in a volume barely larger than a pack of 48mm x 18mm Chewing-gum. Arduino Micro is a real 8-bit micro-controller with native USB support, 32K flash memory and 2.5K RAM. You can program it directly through the micro USB connector (or, for advanced users, via 6-pin ICSP connector). The Arduino Micro is a board based on the ATmega32u4 micro-controller (data sheet) resulting from the joint cooperation of and AdaFruit Industries.  

The board includes the processor, the crystal (clock), micro USB connector with fuse, reset button, ISP connector (low-level programming), LED ON, TX & RX (reception and transmission), a user LED connected to pin the #13 and a 3.3V regulator. You will need to get a micro-B USB cable to connect this board to your computer (see the accessory section). 

You can use the Arduino Micro with the sketches Arduino example but also use it for USB projects client projects. It will be possible for example to get your project for a keyboard / mouse from your computer! Although it isn't compatible with shields (because of its shape), the Arduino Micro has all the same pins as a Leonardo.  
Perfect for reducing the size of your project or for using it directly on a breadboard.

This version is delivered with the pre-welded pinHeader and works in 5V logic with a 16MHz crystal.
