The LilyPad Simple just got a whole lot… simpler. We’ve updated the Simple board to create the LilyPad USB by replacing the classic ATMega328 with the new ATMega32U4. Not only does that mean that it’s running a variation of the latest and greatest bootloader, but it also means no more FTDI Basic! 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!

## Description

The LilyPad Simple just got a whole lot… simpler. SparkFun have updated the original LilyPad Simple board to create the LilyPad USB by replacing the classic ATMega328 with the new ATMega32U4. Not only does that mean that it’s running a variation of the latest and greatest bootloader, but it also means no more FTDI Basic is needed to program your Lilypad!

That's right! **The only extra piece of hardware you need to program the LilyPad USB is [a micro-USB cable](https://core-electronics.com.au/micro-usb-cable.html)**. 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!

Just like the LilyPad Simple, this board features a JST socket ([read more on JST here](https://core-electronics.com.au/tutorials/what-is-a-jst-connector.html)) so you can directly connect any of [our 3.7V Li-Po batteries](https://core-electronics.com.au/power-batteries/liion-lipoly.html) for power. There's also an onboard 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 LiPo battery is even rechargeable through the board, no more special external LiPo chargers required, just connect your board to a USB power source!

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:** A portion of this sale is given back to Dr. Leah Buechley for continued development and education of e-textiles and also to Arduino LLC to help fund continued development of new tools and new IDE features.

**Dimensions:**

- 50mm outer diameter
- Thin 0.8mm PCB
