The Build - 2 - Parts and Tools

1.) Microduino Core + ATmega 644PA / ATmega1284P, 8mhz, 3.3v - http://www.microduino.cc

this one is a bit tricky to find. They don't sell the 3.3v 8mhz version yet, but its fairly simple to mod one to 8mhz. You'll need this for low power.

2.) 3.3v Voltage regulator - http://www.pololu.com
