It’s is M.2, but not the M/B+M key most M2 SSDs use but rather a A+E meant for WIFI/Bluetooth. According to this video it’s essentially 2 PCI Express x1 lanes and USB 2.0. The video goes on to explain some possible alternative uses:
A gigabit ethernet adapter
2x SATA ports for a standard SATA drive
Coral tensor processor
SD card reader
2x USB A-type ports
Some type of SIM card adapter (video wasn’t quite sure on it either)
A PCI Express x16 slot that only functionally works as a x1
So while does this slot has it’s uses, it’s not meant to be used for M.2 drives but rather WIFI.
