Mini PCIe and mSATA share the same form factor and have similar electrical
pinout assignments on their connectors. There’s no clear mechanism to
distinguish if a mSATA drive or a Mini PCIe device is plugged into the socket
until recently that SATA I/O issued an ECN change (ECN #045) to redefine
pin-43 on mSATA connector as “no connect” instead of “return current path”
(or GND). When mSATA drive is inserted, its pin-43 is “no connect”, and the
respective pin on the socket is being pulled-up to logic 1. When a Mini PCIe
device is inserted, its pin-43 forces the respective pin on the socket to ground,
or logic 0.
SW2 is for switching mSATA drive and Mini PCIe device:
