The LilyPad Arduino Simple 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. Unlike the LilyPad Arduino Main Board, the LilyPad Simple has only 9 pins for input/output. Additionally, it has a JST connector and a built in charging circuit for Lithium Polymer batteries. The board is based on the ATmega328.
