The 5V DFduino Pro Mini V1.3 is a microcontroller board based on the ATmega328. This Arduino Pro Mini compatible board operates at 5V and runs the 16MHz bootloader. Make sure to 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.

The board features 14 digital input/output pins, with 6 of them capable of being used as PWM outputs. It includes 8 analog inputs, an on-board resonator, a reset button, and mounting holes for pin headers. Additionally, a six-pin header can be connected to an FTDI cable or a 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 the following items to program and supply power for your Mini Pro board.

Note:Compared with DFduino Pro Mini V1.2, this V1.3 reverses the pins of the programming interface.
