Hello, I just got the EM9191 working via PCIe using these two adapter boards. I figured I would post the info here in case it helps anyone out…
Ableconn PEX-MP117 Mini PCI-E to PCI-E Adapter Card
Ableconn MPEX-134B Mini PCIe Adapter with M.2 Key B Slot
I had to drill an extra little hole in the M.2 to Mini PCIe adapter, in order to fasten it in with a screw considering the adapter does not come with a mounting hole for a 3052 card. But that was extremely simple and straight forward.
