The Arduino® Micro is a compact and versatile microcontroller board, based on the ATmega32U4. Developed in partnership with Adafruit, it is designed to be easy to integrate into projects, particularly those requiring a small form factor that can fit onto a breadboard.
Key Features
Processor: The ATmega32U4 microcontroller offers built-in USB communication, allowing the board to emulate a mouse or keyboard when connected to a computer, eliminating the need for a secondary processor.
Form Factor: Small and breadboard-friendly, perfect for compact designs.
USB Connectivity: Supports direct USB communication via a micro USB cable.
