So, I built my first HM this week. I got everything put together, Rpi Zero W hooked up and was playing with it last night. No issues. Today I finished wiring my servo/fan and plugged it into the HM. I plugged the HM in and it started to boot up but then the LCD went blank and the LEDs seemed to indicate an issue. If I unplug the Rpi the heatermeter works fine, including the fan and servo. When I plug the Rpi into a UsB power source with or without a microsd card it gets burning hot to the touch almost immediately and doesn't respond. The HM and RPi were in the 3d printed case the whole time. Did I somehow fry this thing? Is there something I can check for? I have a Rpi 3b+ I could try but I'm afraid to plug it in. Any tips would be appreciated.
This site seems to indicate my GPIO is somehow messed up.
Pi Zero W Overheat
I've been testing the voltages on my HM via the GPIO. My 5v lines are solid. The 3v3 lines are not 3.3v though. They seem to climb from 0-100mv and then start over. There is another 3.3v lead on the board near the probes and it has a solid 3.3v as well. Is that an actual problem? EDIT: The 3.3v doesn't seem to be an issue. I think that would be 3.3v FROM the Raspberry pie, which we're probably not using.
