Sparkfun now sells a variation of the Arduino called the “Arduino Pro”. Check out the specifications to see if it’s the right board for your next project. If you are new to micro-controllers, I would start with an Arduino Diecimila since the Pro needs a few thing to get it connected. The Arduino Pro is BYOC, that’s “bring your own connectors”.
It’s blue! It’s skinny! It’s the Arduino Pro! SparkFun’s minimal design approach to Arduino. This is a 3.3V Arduino running the 8MHz bootloader (select ‘LilyPad’ within the Arduino software). The Arduino Pro is very much like the Skinny, but we added a handful of features to become a fully certified Arduino board. The power switch was moved to the side of the board (good idea Limor!) to allow control when a shield is attached.
