The Lilypad Arduino is an ATmega32U4 microcontroller board designed for wearables and e-textiles. The Arduino Lilypad can be sewn to fabric and connected to power supplies, sensors, and actuators with conductive thread. It can be programmed with the Arduino IDE, and powered with the USB connection or an external power supply. If an external power supply is used, it must not exceed 5.5V, and the polarity must not be reversed, or the Lilypad will no longer function.
