Arduino Pro Mini


Product Description

  • The Arduino Pro Mini is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 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 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 ArduinoMini.
  • Please note that we currently sell two versions of this board, a 5V/16MHz version (HCARDU0059) as pictured above, and a 3.3V/8MHz version (HCARDU0081). 
  • This product is manufactured by Deek-Robot and is derived from the SparkFun(TM) Pro Mini reference design which was released under the Creative commons Attribution-ShareAlike 3.0 licence.
