I am hoping to get some Insite into what to do next..... the situation:
I installed the (new) mini buck converter backwards. Plugged in the heater meter and it fried my pi zero. Now I am getting 0v at the plug, I have been able to get 1-3v at the 12v pin on the buck converter but no voltage anywhere else
What I have tried so far
Replaced both base board diodes
Replaced Q3
Replaced the power jack
I have another HM that the power supply works ok
My next step will be to replace the MOSFET
Any suggestions would be appreciated
