So far so good with the third Pi. Been running on 12V for the last hour or so with no issue. I think my second Pi just suddenly died (first I obviously fried). Just need to troubleshoot my damper now - he’s getting the voltage out the CAT5 keystone - may be a bad solder joint on the servo...

I thought the same thing. Installed the image on a new SD card and got no activity lights. Nothing booted. Then as you said, I tired connecting the Pi via the USB to my computer (non power port) and the BCM device didn't show up.

The readings above are from just the baseboard only on 12V. I'm fairly certain the first Pi I matted incorrectly when not paying attention which fried it via 12V. That Pi gets quite warm on the main chip. What's weird about the second Pi - it worked by powering the whole HM via the USB...

I re-read the SCK at more fine grain setting on the multimeter and I do see if toggling at a very low voltage (.01-.02). I also re-read everything on a fine grain setting: -MIS = sometimes floating around .04, sometimes constant .01 -TXD = about .17 -RXD = 3.3 -SCK = toggling around .01 -5V =...

With baseboard only on 12v - I did not see anything other than 5 and 3.3. (on the Pi connector) Am I suppose to be seeing something on SCK and MIS? Or are you just saying that's the only PIN actually connected.

Yes I tested the Pi two 5V and G25 (3.3) points and they came back normal. For what it’s worth when powering the Pi via USB. The LCD lights up and works as expected.

Im at a lose, I fried another Pi Zero. I tested the baseboard/LCD only on 12V and all my 5, 3 and 12V points. They all came back good. I matted the Pi to the HM and powered the Pi via USB. The HM came up great, every probe worked great, and no issues reported in the GUI. When I tried the...

Thanks for the info! I'll test some more on my board about the voltage. I'm 99% sure this is just me being stupid. I likely had a bad reading from my multi-meter/wrong setting and I likely matted the Pi on the wrong pins which cause it to fry. I don't think there is anything wrong with my...

Thanks for the quick reply. Concerning, the 100k resistor - is the required even if using the thermoristor? The instructions made it sound like it was 10K for Thermoristor or 100k for thermocouple (not both) Opps, looks like the solder side didn't upload, here it is...

Hi I recently completed my HM 4.3.4. I connect my Pi Zero W to it yesterday both with 12v and USB. It booted right up. Today, I was starting to work with it again and it fried my Pi Zero. I then check the 5V points and I'm getting 10v. On my 3V points Im getting 6V. Any help of where to...
