OpenEVSE II

I sat down today and sketched out a new design for OpenEVSE. I call it OpenEVSE II. It's completely compatible with the existing OpenEVSE firmware. It is designed as two boards - the first is an HV + Relay board that has the AC power supply, two 30A relays and the AC test functionality. You connect the AC power and J1772 cables to QD terminals in the tops of the relays. The board itself has a 4x2 DIP header that connects via a cable to the controller / display board, which is a semi-backpack board (it's slightly larger than the 16x2 LCD that's it's sandwiched to).

Here are the schematics:

The design isn't yet proven, so don't be in a hurry to go build one just yet... But I hope to have it ready shortly.
