LilyPad USB ATmega32U4 Board

The LilyPad USB ATmega32U4 Board is a round, sewable Arduino-compatible board for wearable and e-textile projects. The ATmega32U4 has native USB, so you program it straight from the Arduino IDE over micro-USB, and the same port charges a LiPo battery plugged into the on-board JST socket. Large pads let you sew LEDs, sensors and buttons to it with conductive thread.

What's in the Box

• 1 × LilyPad USB ATmega32U4 board

Tip: The board runs at 3.3 V, so do not feed 5 V signals into its pins. Select 'LilyPad Arduino USB' in the Arduino IDE, and turn the switch on when running from a LiPo battery.
