Hello. Since few (if any) computers have an open M.2 slot supporting modules 30mm wide by 52mm length, I want to select a “PCIeMiniCard-to-M.2 B-Key” adapter for using the PCIe lane in a full size mPCIe slot to link to a standard host computer. (I don’t want to use USB to link to the host because standard PCIe Mini Card slots only support USB 2, which would limit the bandwidth to perhaps 400Mbit/s.)
Please share recommendations for which mPCIe to M.2 adapters have been successfully used with Em9190 or Em9191.
Section 3.4 of the AirPrime EM919X-EM7690 Product Technical Specification says “Host support for PCIe 3.0 signals is required when PCIe is selected as host interface.” If attempting to use a host which supports PCIe Gen 2 but not PCIe 3.0, would the Em9190 or Em9191 fail to link to the host computer, or what would be the problem? (Is it planned that a future Em919x firmware upgrade will allow support for hosts which support PCIe Gen 2 but not PCIe 3.0?)
