The Arduino Pro Mini is SparkFun's minimal design approach to Arduino. It's essentially a 5v Arduino that runs an 16 MHz bootloader on a super small, super thin board. There are no connectors attached - allowing you to add whatever connectors or wire you want without too much trouble. The goal of the Pro Mini isn't to replace the Arduino so much as bring the cost down for more advanced users. The Arduino Uno is still the inimitable board but if you're comfortable working within voltage limitations, don't mind off-board USB, and want to customize your connectors, the Arduino Pro Mini's a great budget purchase. You will need an FTDI friend or FTDI cable to program your Pro Mini, and we also recommend some plain header to solder it for breadboard
DESRCRIPTION:
The Arduino pro mini is a small, complete, .based on the ATmega328P. It has more or less the same functionality of the Arduino Duemilanove, but in a different package. The professional version of the Mini Pro is a microcontroller board. It has 14 digital input/output pins (6 of which can be used as PWM outputs), 8 analog inputs, a 16MHz resonator, a reset button, and mounting hole pin headers.
