The new version of this kit adds extras of the small components to help you out if you misplace a super tiny resistor. It also has small corrections to the manual and better instructions. This is a kit of loose components that go along with the . This is considered an intermediate kit for people who have soldered before and wish to learn how to solder surface mount components. This kit does not include a programmer or a battery. You will need an external programmer to program the firmware onto the ATmega328. All parts are listed below.
