Arduino Pro Mini 328 - 3.3V/8MHz

We expanded our Aruduino lineup with Sparkfun's "Arduino Pro Pro" This minimal design to Arduino is a 3.3V Arduino running the 8MHz bootloader (select 'Arduino Duemilanove w/ 328' within the Arduino software)

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.

Please note: Arduino 0015 supports the ATmega328 but not yet at 8MHz. Please select 'Arduino Duemilanove w/ 328' within the Arduino software but expect your delays to work twice as long (code will run half as fast as the Duemilanove at 16MHz).
