My OpenMV Cam H7 was working fine but once, I plugged 5v in 3.3v pin (or I used + and - instead … Not sure really what I’ve done!) And then my camera stopped working and when I powered it up, the LED doesn’t shine and it doesn’t work at all. Could you please give me some help? How can I fix it?
5v into the 3.3v pin would definitely destroy the main processor and camera sensor.
Reversing the power wouldn’t normally do that on Vin since we have diode power protection.
If you reversed the power on the 3.3v pin would break the system even more than 5v unreversed because the voltages would add to 8.3v.
