Smoke and burning smell after connecting ethernet cable
Hi,
I have recently encountered an issue with my heater meter 4.3 raspberry pi zero W setup. It was working fine with my micro damper setup however I wanted to test it with just using a fan so I soldered up an Ethernet cable to a 5.5mm dc power jack. I plugged this in and was trying to test the fan in manual mode however i noticed the ethernet cable getting hot and there was a nasty smell and smoke coming from the heatermeter.
I quickly disconnected the ethernet cable and tested the unit again with my micro damper but noticed that the fan in voltage mode would only come on at 100%. I then decided that i would leave it alone and come back to it later before i made things worse.
When I did come back to it I tried testing the output volatage on the microdamper jack and the fan output was showing 12V on 5% output. I then went to reconfigure the output to pulse mode and found I could no longer access the web interface raspberry pi was getting hot. At this point it seemed everything was going wrong so I stopped again and decided to write up the issue and ask for help here...
I have ordered a new pi zero W but I am wary of plugging it in in case it suffers the same fate as the first.
I have a soldering iron and multi-meter so should be able to solve the issue.
Any help or advice would be much appreciated.
Cheers
Tim
