Adafruit launches a new platform for the development of wearable devices:
Gemma is a tiny wearable platform board with a lot of might in a 1″ diameter package. Powered by a Attiny85 and programmable with an Arduino IDE over USB, you’ll be able to realize any wearable project!

The interesting thing about GEMMA is not the functionality itself (as it sports only three I/O pins – that seems the highest limitation) but the size.
In fact Gemma is just half the size of Lilypad (1 inch vs 2 inch) and it opens new interesting opportunities with regards to ultra small / lightweight applications. Are you working with wearable devices?

Can the Gemma work with LilyPad Xbee?
