LilyPad Arduino 328 Main Board

Part Number LILYP-398328 Categories , ,

This is LilyPad Arduino – the 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. The back side of the LilyPad is now completely flat! We now use a surface mount programming connector to keep the header from poking through.


LilyPad is a wearable e-textile technology developed by Leah Buechley and cooperatively designed by Leah and SparkFun. 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!

Note: Do not power the LilyPad Arduino with more than 5.5V, or plug the power in backwards as it will destory the board.
