SquareWare by Ray’s Hobby offers the same general format as a Lilypad or Flora but uses a PIC microcontroller:
An open-source microcontroller board designed specially for wearable electronics projects. It’s small (1.6″x1.6″) and square! Has 8 general i/o pins and 4 power sink pins suitable for driving high-current load. Comes with built-in USB connector and li-po battery charger.
(You may recall Ray’s Hobby from this year’s MakerFaire Bay Area when they demonstrated their OpenSprinkler control system.)
