Seeed Odyssey M.2 PCIe clarification

Does the M.2 B-key support both 2242/2280 M.2 interfaces ?

in some places it says both M.2 are PCIe (2280) but in others it refers to the B-key as SATA (2242).

in the tech specs it lists

“M.2(Key B, 2242/2280): SATA III, USB2.0, UIM”

was hoping someone could confirm the B-key slot does support 2280 (PCIe) ?

thanks,

@Trinkner Odyssey J41*5 only support SATA SSD in B key solt.
