The 3.3V DFduino Pro Mini 8Mhz(Arduino Pro Mini Compatible) is a microcontroller board based on the ATmega328.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 the official Arduino Pro Mini. The DFRduino Pro mini has 8 analog inputs compared with the 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 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.
