The Keyestudio PRO MICRO development board features the ATMEGA32U4-MU processor core, fully compatible with Arduino. It offers 18 digital I/O pins (including 5 PWM outputs), 9 analog inputs, a 16 MHz crystal oscillator, and a micro USB port. Operating at 5V, it can be powered via micro USB or a 7-9V DC supply through the RAW pin. Designed for easy integration into interactive projects, the board comes without pre-soldered pin headers, allowing custom configuration. The package includes two yellow 1x12 2.54mm pin headers for flexible physical design.
