It looks like DigiKey is out of stock of the MangOH reds, we have 3 MangOH units that get very hot when we connect power to them and 2 units that are fine (but now deployed on boats for testing).
We had done one modification to each of the MangOHs where we had removed R371 and placed a 0ohm resistor at R382. We haven’t appeared to have any problems with that modification - we had done this several months ago on all of the units. However, over the past couple of weeks we have found 3 of our 5 units drop off and they now each read 1.7V on the 3.3V RPI lines and get extremely hot as soon as power is connected.
Anyways, does anyone know where there’s still stock of MangOH red units?
