HV is reference high voltage, LV is reference low voltage, and the hv and lv 1-4 are the 4 bi directional channels. I was hoping to give this a shot, at least until the other unit arrives which may be a while. Tx and Rx and ground are fed from the 497 to the high side channels and tx, rx, ground and 3.3v from the wemos d1 mini to the low side. The 3.3v and ground from the wemos go to the low reference voltage to tell it what to step down to. So here's my question: For the high side, I have ground coming from the hand controller and that would be going to reference. Now I can either draw 12v from the aux port or an external power supply to feed into the high reference, but what exactly do I do with the ground from the external power supply or aux? I already have the ground coming from the 497
