The Arduino Pro Mini is a microcontroller board based on the ATmega328.
It consists 14 digital input/output pins (of which six can be used as PWM outputs), six 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 Sparkfun breakout board to provide USB power and communication to the board. The Arduino Pro Mini ATMEGA328 is for advanced users who require flexibility, low-cost, and small size. This is a 5V Arduino running the 16MHz bootloader. Arduino Pro Mini does not come with connectors populated so that you can solder in any connector or wire with any orientation you need. Be sure to provide the correct power and use components whose operating voltage matches that of the board.
The board comes without built-in USB circuitry, so an off-board USB-to-TTL serial converter must be used to upload sketches. This can be an FTDI TTL-232R USB – TTL Level Serial Converter Cable for the 5V Arduino Mini Pro), or an FTDI TTL-232R-3V3 USB – TTL Level Serial Converter Cable. One quick way to connect these is by inserting a six-pin 0.1″ male pin header into the end of the FTDI cable or breakout board, and pressing it against the six-hole programming header on the Mini Pro, And the operating temperature is Between -20C to 80C
You can power up the board through USB via the six-pin programming header, or from a regulated 5V (depending on the model) supply applied to the VCC pin or an unregulated supply on the RAW pin.
You can also solder any standard 0.1″ spaced header to the holes on the Arduino Pro Mini. To use every pin requires two 12-pin headers, plus a six-pin header for programming if desired. We can also solder bare wires to the holes.
