Description:
   
   The Pro Mini is a microcontroller board based on the ATmega328 for . With 14 digital input / output pins (of which 6 can be used as PWM outputs), 8 analog inputs, an on-board resonator, a reset button, and holes for mounting pin headers. Six pin header can be connected to an FTDI cable to provide USB power and communication to the board.
