OPPO Digital A103

OPPO Wireless Adapter

This device is assumed to be using RT5370 based on the chip size and Ralink logo.

"2052500318 Rev:1.1" is silkscreened on the board. "PW-DN427" is referenced on the label design FCC docs. This would seem to imply that the device is a newer model Proware PW-DN427.
