Yes, I have 5.0 volts measured with a calibrated digital VOM. Using pins 2 &6. The inline measures 5.01 90% of the time as the lowest point.

I see the same thing on my system. It boots, and runs fine, no extra heat. I have a usb power line monitor, and it never goes below 5.1vdc and never more than .27amps.. so I don't know. I have tried several 5volt power units and I get the same thing on each one. maybe the low volt sense is off. Wish...
