Is this B key or M key?

[sber]

Just bought a ​INTEL® SSD 660P SERIES

(1.0TB, M.2 80mm PCIe* 3.0 x4, 3D2, QLC)

I have a motherboard which is compatible with M.2_1 and M.2_2 sockets type 2280, with M key. It doesn't say anything about B key compatibility.

Is this Intel SSD compatible with my motherboard? Is it M key?​

Yes, it's a NVMe​ PCIe x4 Type M device, so it must be used in a socket supporting Type M or Type B+M.
