DFRduino Pro Mini 8 Mhz (Arduino Pro Mini compatible)

The DFduino Pro Mini (Arduino Pro Mini Compatible)  is a microcontroller board based on the ATmega328.

It is an adance version of offical Arduino Pro Mini. The DFRduino Pro mini has 8 analog inputs compared with offical 6.  The rest bits are exactly the same.

It has 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. A six pin header can be connected to an FTDI cable to provide USB power and communication to the board.

The DFRduino Pro Mini is intended for semi-permanent installation in objects or exhibitions. The board comes without pre-mounted headers, allowing the use of various types of connectors or direct soldering of wires. The pin layout is compatible with the Arduino Mini.
