[Solved] Hat Not Working, Forum not working, pulling my hair out
Connect 12V DC to the HAT (round connector) and 5V DC to the raspberry (micro USB connector).
NOTE: Make sure you switch on the both power sources at the same time to avoid software trouble.
i just wanted to report back. I ended up buying a second fabscan Hat and I couldn't get it to work either. So I called watterott, mailed my pictures and described my attempts and they agreed to attempt to fix the hats for me.
I sent both Hat's to them and they flashed the bootloader and reworked the soldering, both of them are working now.
Superb Support, very Happy now.
If anyone needs a working Hat, I've got a spare one now, PM me.
