LilyPad 328 Main Board

The LilyPad Arduino 328 Main Board is an Arduino-programmed microcontroller that is easily integrated into e-textiles and wearable projects. It offers the same functionality you find in other Arduino boards in a lightweight, round package designed to minimize snagging and profile, with wide tabs that can be sewn down and connected with conductive thread.

The LilyPad Arduino consists of an ATmega328 with the Arduino bootloader and a minimum number of external components to keep it as small (and as simple) as possible. This board will run from 2V to 5V and offers large pin-out holes that make it easy to sew and connect. Each of these pins, except (+) and (-), can control an attached input or output device (like a light, motor, or switch).

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!
