Arduino Micro Board

DESCRIPTION: The Arduino Micro is a compact microcontroller board based on the ATmega32U4. Designed for projects requiring USB communication and small form factor integration, it can emulate a keyboard, mouse, or virtual serial port. Its breadboard-friendly design makes it ideal for prototyping, embedded systems, and interactive applications.
 
KEY FEATURES:
Built on ATmega32U4 microcontroller with integrated USB communication
Can emulate keyboard, mouse, and virtual serial/COM port over USB
16 MHz crystal oscillator for stable timing
Micro USB connector for programming and power
ICSP header and onboard reset button for easy control
Small form factor for breadboard compatibility and compact projects
