LilyPad Arduino USB

The LilyPad Arduino USB Board is a small sewable computer. It can be stitched to fabric and connected to other electronic pieces with conductive thread. This LilyPad board has 11 pins — the silver petal-like tabs that ring the outside of the board. Each of these pins, with the exception of (+) and (-), can control an attached input or output device (like a light, motor, or switch). This board is based on the ATmega328U4 microcontroller. The microcontroller is the black square in the center of the board (top view). You can program this LilyPad board using the Arduino programming environment.
