The Dfrduino Pro Mini V1.2 (Arduino Pro Mini Compatible) is a microcontroller board based on the ATMega328. It is a 5V Arduino running the 16MHz bootloader (select ‘Arduino Duemilanove w/ 328′ within the Arduino software).
The board is an advanced version of official Arduino Pro Mini. It has has 8 analogue inputs compared with 6 on the official boards. The rest are exactly the same.
It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 8 analogue 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 Arduino 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 to your Pro Mini board.
1. FTDI Basic Breakout 3.3/5V (Arduino Compatible)
2. USB Serial Light Adapter (Arduino Compatible)
