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!
