This main board consisting of an ATmega328 with the Arduino bootloader and a minimum number of external components to keep it as small (and as simple) as possible. Board will run from 2V to 5V. The latest version of the LilyPad supports automatic reset for even easier programming.
This version of the LilyPad now uses the new ATmega328 at 8MHz. Suitable for Arduino Pro Mini 328/8MHz/16MHz. Each LilyPad was creatively designed to have large connecting pads to allow them to be sewn into clothing. Various input, output, power, and sensor boards are available. They're even washable!
