Disclosure: This project operates the ATmega328-P-PU outside the published ATmel specifications: According to ATmel, the 328P requires slightly over 3.3V to reliably start the oscillator at 16MHz and to otherwise perform acceptably.  Lab testing here at SofKinetics has shown that the ‘board-duino’ 328P-PU can withstand below freezing and above 130F temperatures and that the 16MHz crystal …
