Sparkfun just released yet another Arduino variant, the Wii “Wee” –
SparkFun’s minimal design approach to Arduino. This is a 3.3V Arduino running the 8MHz bootloader (select ‘LilyPad’ within the Arduino software). The Wee is not a fully certified Arduino board. We’re working with Arduino.cc towards certification.
We really wanted to minimize the cost of an Arduino. The Wee is like the Arduino Mini (same pin out) but to keep the cost low, we used all SMD components, made it two layer, etc. This board connects directly to the LilyPad USB Link
