About this item

The Pro Micro is a compact Arduino-compatible board featuring the ATmega32U4 microcontroller with built-in USB connectivity, eliminating the need for an external USB interface. Operating at 16MHz and 5V, it offers 12 digital I/O pins, 5 PWM outputs, 9 channels of 10-bit ADC, and hardware serial connections (Rx and Tx). Its small form factor makes it perfect for space-constrained projects. With an onboard voltage regulator, it accepts input voltages up to 12V via the RAW pin (not VCC), providing flexibility in power supply options while delivering familiar Arduino functionality in a tiny, versatile package.
