Silvester and I are wondering whether it is OK or even productive to feed +5V into the 5V terminal on the 4-pin Grove connector - it's not too clear from the above whether this is something you do or you avoid doing, but the destructions I copied from the (not yet final) manual for the M5StickCplus version of your loader seem to suggest that this is a connection that should be made. (Post #195).

Could you clarify what the actual position is in that respect?

In your second image above you show that the cable loom for your Atom modules intentionally has the +5V wire removed at the module end, and the M5Stick cable looks like it is coming out of the 8-pin end of the module via a proto-hat. Silvester reckons it is actually OK to feed +5V into the 5V - in terminal there but not into the 5V terminal on the 4-pin Grove connector, which looking at the schematic is an output only?
