GETTING TO KNOW YOUR IPC-R1ix
Both mSATA and Mini PCIe share the same form-factor and similar electrical
pin-out assignments on their connectors. There was no clear mechanism to
distinguish if a mSATA drive or a Mini PCIe device is plugged into the socket
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.

drive and Mini PCIe device.
