The Pro Mini Clone is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, an on-board resonator, a reset button, and holes for mounting pin headers. A six pin header can be connected to an FTDI cable or USB-Serial breakout board to provide USB power and communication to the board. There are two versions of the Pro Mini. One runs at 3.3V 8 MHz, the other at 5V 16 MHz.
