Yes, Ludwig, I forgot about the possible effect of the A/D input.
the voltage difference 3.3V - 3.0V = 0.3V looks like from a protection
But the measurement he stated at Q111 was 10.6V and 3.3V on ADC_3V3, so the difference would be?
5.3V - 3.3V = 2.0V, which I don't think would happen from the A/D input.??
Or maybe I misunderstood his measurements.
