It is a 3.3V DFduino running the 8MHz bootloader (select 'Arduino Duemilanove w/ 328' within the Arduino software).

It is an advanced version of official Arduino Pro Mini. The DFRduino Pro mini has 8 analog inputs compared with official's 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 or DFRobot breakout board 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.

We recommend that you choose one of following items to program and supply power for your Mini pro board.

1. FTDI Basic Breakout 3.3/5V (Arduino Compatible).
2. USB Serial Light Adapter (Arduino Compatible).

Note: Compared with DFduino Pro Mini 8Mhz(Arduino Pro Mini Compatible), this V1.3 one reverses pins of the programming interface.
