We expanded our Aruduino lineup with Sparkfun's "Arduino Pro Mini" This minimal design to Arduino is a 3.3V Arduino runing the 8MHz bootlader (select 'LilyPad' within the Arduino IDE.)

The Arduino Pro does not come with the connectors populated so that you can solder in any connector or wire with any orientation you need for your exact project. We recomend first time Arduino users start with the Arduino Duemilanove It's a great board that will get you up and running quickly. The Arduino Pro series is meant for users that understand the limitations of the 3.3V system voltage, lack of connectors and no USB on board.

The Arduino Pro is designed for low profile use and is recommended to be powered with a LiPO battery for great portability as well. If you need regular DC power a standard jack can be soldered onto the unpopulated pads.

This board connects directly to the FTDI Basic Breakout board for sketch uploading (supports auto-reset) and can be used with a standard FTDI cable but without auto reset.

Features

low profile

ATmega168V running at 8MHz external resonator

USB connection off board

3.3V regulator

Reverse polarity protected

DC input 3.3V up to 12V

Resettable fuse prevents damage to board in case of short

Power select switch acts as on/off switch
