Product Description

DESCRIPTION:

• It contains everything needed to support the microcontroller; simply connect it to a computer with
  a micro USB cable to get started. It has a form factor that enables it to be easily placed on a breadboard.
• The Micro is similar to the Arduino Leonardo in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Micro to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port. It also has other implications for the behavior of the board; these are detailed on the getting started page.
