Pro Micro (Arduino Board Compatible)
The Pro Micro is an for Arduino compatible microcontroller development board based on the ATmega32U4 IC designed by Sparkfun Electronics. It is based around the for Arduino Leonardo which means you no longer need an addition USB-Serial Interface to program your for Arduino. Just plug in the board, download the addition for Arduino add-on and your ready to start programming!
The board is broken down into 24 individual pins and has 3 indication LEDs, one of which is dedicated to power. It features 4 channels of 10-bit ADC, 5 PWM pins, 12 DIOs as well as hardware serial connections Rx and Tx. This version run on 3.3V at 8 MHz and can also run on 12V supplied to the “RAW” pin.
