This is an ATmega32U4 based microcontroller board, The Pro Micro features an on-board micro-USB connector for instant USB connectivity that also doubles as a power supply! Ideal for small, lightweight projects that require rapid prototyping or in large volumes.
Features
It includes 4 analogue pins with 10-bit ADC (Analogue Digital Conversion) for use with analogue 3.3V sensors,
5 PWM (Pulse Width Modulation) pins good for dimming LED’s,
12 Digital I/O pins for general use
Rx and Tx hardware serial connections.
This Pro Micro contains an on-board USB transceiver, so it doesn’t require any external FTDI boards to be able to connect it to a computer.
