Introduction
The DFduino Pro Mini (Arduino Pro Mini Compatible) is a microcontroller board based on the ATmega328.
It is an advanced version of official Arduino Pro Mini. The DFRduino Pro mini has 8 analog inputs compared with official 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 Serial Adapter 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.
Note: The board requires FTDI basic board to upload sketches. It can be powered by a mini USB.
