Description Arduino Lilypad Overview The LilyPad Arduino is a microcontroller board designed for wearables and e-textiles. It can be sewn to fabric and similarly mounted power supplies, sensors, and actuators with conductive thread. The board is based on the ATmega168V (the low-power version of the ATmega168) (datasheet) or the ATmega328V (datasheet). The LilyPad Arduino was designed and developed by Leah Buechley and SparkFun Electronics.
