Oops, I connected a 24V power supply to the SATA Hat and I think I blew the diode on the hat. (see photo) Not sure if it is a diode, which way should it be orientated. Stupid idiot for creating the magic smoke, I hope I can repair it. I tried booting the Orange Pi I had already connected to it (because the original NanoPi M4 is missing... Fortunately the OrangePi is OK.
Any advice on where to look if the diode in question does not fix it.
Cheers,
James
