Looks like one to me. Remember that M.2 is a form factor. You can have an M.2 slot that does not support SSD storage for example. I have one that is only intended to work with wifi adapters.
Based on the wifi designation on the board I’ll bet it only works with wifi cards.
M.2 is a form-factor. It talks about the shape only, it says nothing about what the device you are using can do. Many boards have restrictions on supported devices for the physical slot.
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.
