[SOLVED] Anyone recommends diagnostic POST cards?

[Rodion15]

I'm a Computer Repair technician.

I sometimes think..."what about those POST cards"...I heard there's USB POST cards too?... I guess they're mostly PCI Express nowadays. I wonder if they may be useful to troubleshoot dead motherboard issues or when putting together PCs...

I'd welcome any advice on this...

I got a KQSW4 4 Bits Diagnostic USB Test Card from Aliexpress.
Link on Amazon but it isn't available.
