In a datasheet of a embedded device (this one in my case) what does it mean that the PCIe bus is conneceted to a socket that says "Full-size Mini-PCIe (colay mSATA)"

    \$\begingroup\$ 1) the included link doesn't work. 2) "colay" doesn't seem to be a proper word, maybe it is an abbreviation. 3) maybe the "Full-size Mini-PCIe" connector also has pins for a SATA interface (for an mSATA SSD). Some of my Dell notebooks have this, the PCIe slot supports mini PCIe cards but also mSATA SSDs. \$\endgroup\$ – Bimpelrekkie Oct 31 '19 at 13:21
  • \$\begingroup\$ 1) Link updated, thanks 2) I know, it doesn't show up in any dictionary that I could get, but if you google "colay mSATA" many datasheets appear 3) Ok, that was my suspicion but I haven't seen it in the real world, I'll do some tests whenever I get the board \$\endgroup\$ – Sanjo Nov 5 '19 at 9:37

Mini-PCIe and mSATA are two different standards but which use the same physical connector. However they are not intercompatible by default.

As far as I can tell, "colay" is probably an abbreviation for co-layout, or co-support, indicating that the slot simultaneously support both the Mini-PCIe and mSATA standards allowing both types of cards to be plugged in.

This is confirmed by reading the link you post to. In the table under "Internal I/O", it says "Mini-PCIe: 1 (full size, support mSATA)"
