⚡ Arduino Pro Micro – ATmega32U4 5V/16MHz Mini Microcontroller Board
⭐ Product Description
The Arduino Pro Micro is a compact microcontroller board based on the ATmega32U4, featuring 5V operation and a 16 MHz clock. Its small form factor makes it ideal for space-constrained projects, wearable electronics, robotics, and custom USB devices.
Unlike many other Arduino boards, the Pro Micro can emulate a USB keyboard or mouse thanks to its ATmega32U4 built-in USB functionality, making it perfect for HID projects. It provides 12 digital I/O pins (5 PWM outputs), 9 analog inputs, and comes ready to use with the Arduino IDE.
This board is ideal for makers, students, and engineers who need a lightweight, versatile, and programmable microcontroller for both standard and USB-HID projects.
