  • 2x miniPCIe slots with PCIe3.0 2lane interface for Wi-Fi NIC

Where real lane is one minipci slot?

Hi，

There are 2 lanes in total. The standard minipcie socket only has 1 lane pcie. BPI-R4 uses 4 additional PINs as the second line, which is not standard.

You mean per mpcie socket 2 lanes,right? One per standard and then the 4 additional pins for second…so total of 4 (both slots).

In real-world usage, roughly equivalent to PCIe 3.0 x0.6.

Thanks for the answers. I was interested in this question in connection with the choice of a minipci - pcie adapter.

Where can I find a pinout diagram for mini pci BPI-R4 with extra 4 pin lanes?

There may be recommendations for a common PCIE adapter that does not require modification.
