Re: Prog Rock board voltages

I did, and got +5.3V, and +3.7V, at the locations specified. Are these within spec?  And, if not, what needs correcting?
Hans has said before that the voltages are somewhat higher than nominal. I'm not sure about measuring resistances when fitted, other paths might be involved. If you use the formula for the regulator it comes out at around 5.15V. The 3V3 also calculates at around 3.6 so your readings are as expected.
