Well, this first spin didn't quite go as smoothly as hoped... the stand-alone works just fine but by using net-ties rather than 0R jumpers, I missed the fact that in the ASIC configuration, I'd have conflicts driving the LED FETs... ah well, only making 6 at most, so a little rework will do the trick to getting some in time for supercon.

The awesome news is that it can work.  This is a pico used in place of the badge, to provide power, select a project and clock it... yay!
