    21362136 - FSA for VeniceFLEX / Catalina here: [wiki:FSA#GW16FB0FSAM.2B-KeyAdapter]
    2137  - GW16147 Mini-PCIe to B-Key M.2 Adapter pulls pin 20 low by default, there is no GPIO control
     2137 - GW16147 Mini-PCIe to B-Key M.2 Adapter floats pin 20 by default, there is no GPIO control. There is an optional 0-ohm resistor that is not loaded, R60 to connect pin 20 to ground.

    2596 On the GW16140 M.2 adapter, Pin 22 is not connected, and pin 20 is tied to ground.
     2596On the GW16140 M.2 adapter, Pin 22 is not connected, and pin 20 is floating, with an optional resistor R60 to tie it to ground.
