Arduino LilyPad USB ATmega32U4 Microcontroller

• LilyPad wearable e-textile technology with USB
• JST socket to directly connect a Li-Po battery
• On-board power switch to turn on/off
• Batteries rechargeable through the board

The Arduino LilyPad USB ATmega32U4 Microcontroller is a wearable e-textile technology which is creatively designed to have large connecting pads to allow them to be sewn into clothing. It features a JST socket so you can directly connect a Li-Po battery for power and an on-board power switch so you can turn it off when you’re not feeling particularly blinky. These boards were designed to streamline your next sewable project by keeping things simple and giving you more room to work while eliminating the need to sew a power supply.

The board has been updated to create the LilyPad USB by replacing the classic ATMega328 with the new ATMega32U4. The only extra piece of hardware you need to program the LilyPad USB is a micro-USB cable, since the new IC has built-in USB support. The LilyPad USB is also officially supported in the Arduino IDE as of version 1.0.2.
