Well it took a few hours this afternoon but here's my PCB. A little larger than some of the others on here, but I wanted to build in a linear regulator. It would be possible to use the same pads for a diode regulator if preferred.

The only thing I could not easily fit on a single side was a resistor divider for input voltage monitoring (this could be encoded in the transponder output, like I presume the AMB ones do). I'd prefer to keep it on one side for now and add features later if required.

The only different things are a status LED, two mounting holes and strain relief hole for the input cable.

The ICD header is directly compatible with the PICKit3.

Thanks again to Howard for all his work on this, I'm looking forward to building some boards.
