WiFi cards come in M.2 2230 format with an E key on the slot, The X570 ITX build I’m planning for my 5950X will likely sport these slots. I am hoping that it will be a possible setup to put something there for PCIe 4.0 x1 or x2 . This would be really awesome since with two additional regular M.2, it may be possible to attach 3 PCIe devices in total, this is far beyond what I would have imagined ITX to be capable of!
The question is does anyone know if these desktop gaming oriented boards will actually work with these? I’ve seen adapter products that people successfully use with various laptops but i’d be most likely trying to run a NIC or HBA off it in fringe scenarios. Even if limited to PCIe 3.0 x2, that’s 2GB/s, would not be shabby.
