The new Arduino prototyping kit allows you to build and program your own circuits using the fully functional and production-ready Arduino prototyping board.

The BlinkM packs an ATiny85 micro controller, which allows it to be flashed with the Arduino bootloader thanks to the people over at the [High-Low Tech group at MIT].

[Walter]’s device was based upon the Arduino Leonardo. Starting with the Caterina bootloader, modifications were made to enable the device to be locked and unlocked for programming.
