Looks like a 2-layer board?

Since discontinuing it, I've put up the ExpressPCB design files, too, as was also always the plan. If one were interested in trying to revive the board availability, one would be welcome to as far as I'm concerned. One attempting that should ask ppl and Morsel, too, however.

Yes.

 

Definitely no good for hand-etching in its current state. We knew we were going to make professionally-etched PCBs from the start, so we took full advantage of the tighter margins that affords.

yeah, looked a bit tight for that.  The expressPCB 'standard' process isn't completely cost prohibitive but I'd loose the silkscreen and the solder mask... if I did it I'll let you know so I can send something  your way.

The first several rounds of PPA prototype PCBs were made on that process. Of the three of us involved in the PPA development, I'm pretty sure I assembled and tested more prototype boards than the others, so I feel comfortable assuring you that that silk and mask are very much optional with the PPA. Nice, but not actually necessary for a design with this component density.
