This is LilyPad Arduino - the main board consisting of an ATmega328V with the Arduino bootloader and a minimum number of external components to keep it as small (and as simple) as possible. The Arduino LilyPad can be powered via the USB connection or with an external power supply. Board will run from 2V to 5V. The back side of the LilyPad is now completely flat! We now use a surface mount programming connector to keep the header from poking through.

 This version of the LilyPad now uses the new ATmega328 at 8MHz. Arduino 0016 supports the Arduino Pro Mini 328/8MHz. Use this setting when using this new LilyPad 328.

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! Wash at your own risk - we do ;). We recommend washing projects by hand with a mild detergent. Drip dry. Make sure you remove your power supply first!

The Arduino LilyPad can be programmed with the Arduino software. *Note*, the Arduino LilyPad should only be programmed with software versions 10.0 or higher.

We also recommend this FTDI Basic Breakout 3.3V or the FTDI Basic Breakout 5V serial to USB adapter to program the Lilypad. 

Warning:
Don't power the LilyPad Arduino with more than 5.5 volts, or plug the power in backwards: you'll kill it.
