I built one of the v0.2 TRR power boards today. It all went together pretty well, although I do think that the QD terminals for the hot and out lines are uncomfortably close to each other and the triac heat sinks. The v0.3 boards will have a bit more room around them.
These boards definitely are an upgrade from the prototype board. I'll be installing this one in my oven in exchange for the prototype tomorrow.
