We have ✅ 1 available of the PI-A000053 in our Sydney warehouse.
The Arduino Micro is the smallest board in the Arduino family, based on the ATmega32U4 with built-in USB. Its compact breadboard-friendly form factor makes it easy to integrate into everyday objects and interactive projects. Like the Leonardo, it can emulate a keyboard, mouse, or other USB HID device.
Developed in conjunction with Adafruit, the Micro has 20 digital I/O pins, 12 analog inputs, 7 PWM channels, and a micro USB connection. Simply plug it into a breadboard and connect to a computer to get started.
Key Features
- Ultra-Compact – 48 × 18 mm breadboard-friendly form factor, just 13g
- Native USB – Built-in USB on the ATmega32U4 enables keyboard, mouse, and HID device emulation
