Like all LilyPad boards, LilyPad Arduino Simple Snap is also designed for use in wearables and e-textile. The board is based on ATMega328 microcontroller. LilyPad Arduino Simple Snap differs from other members of the LilyPad family by its two new features. The first one is the built in Li-Po battery used in the board and its female snap connectors. Although LilyPad Arduino Simple Snap is out of the washable class due to its built in battery, its female snap connectors make it possible for the board to easily connect and disconnect to a fabric which has male snap connectors. Therefore being washable is not mandatory for this board. The built in battery can be recharged by using an FTDI adapter. Like all LilyPad boards, Simple Snap has an on-off switch, so you can use your board whenever you need.
