Hi Adrian,
Thank you. I tested to power directly 12V without the power module and the 12V led won't turn on. I used the multimeter in continuty mode and I got a few things which I cannot really understand:
- "OL" between 12V and GND solder.
- "0" between B200 sides.
- "OL" and "-OL" between D1 sides.
I didn't do much more research as I frankly don't really know how to find where the problem is.
I didn't connect anything else into the HAT. I just connected it to the rpi. May it be that I powered it reversed? (I don't remember if I did, but I cannot find any other cause, apart from the 5V charging while power module installed).
Edit: the B200 fuse doesn't get hot now. It seems caput.
Edit 2: I just read another thread in which Sailoog explains the connection of the power switch. I didn't connect the switch. If this is the problem I will love to discover that I'm just another electronic idiot and that the problem may be solved. Let me update you soon, lol.
Edit 3: Problem solved. I think that the problem was that I didn't connect the switch. Lol. Sorry for the inconvenience and thank you so much. Cheers.
