"DIR-853_A1" and "REV1.0" is silkscreened on the board in the FCC photos.

A single MediaTek MT7615DN chip serves both 2x2:2 radios.

The identifier on each of the two Qorvo RFFM4552 5GHz RF FEMs is different

which likely just means that they came from a slightly different batch.
They are: CF75 and CFBF
