Agreed, why not attach it to the internal USB bus? Maybe it’s a sourcing / business deal thing. I’m theorizing most laptop manufacturers have made a deal with m.2 pcie wifi producers and not the usb WiFi producers.

The FPGA has a PCIe endpoint peripheral. Making that available opens up a lot of possibilities.

The M.2 connector provides PCIe, SATA and USB 3. Many WWAN devices on M.2 are for example just USB devices.
