  • The Micro is a microcontroller board based on the Atmega32u4, developed in conjunction with Adafruit.
  • 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 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.
