2.4.11 CN4 : Mini PCIe 1/ mSATA
SW2
CN4
Mini PCIe and mSATA share the same form factor and similar electrical pinout
assignments on their connectors. There is 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 an
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.
SW2-1 is for switching mSATA drive and Mini PCIe device.
