Panda Wireless PAU0B

Overview
"BL-R7610RA1 V1.0" is silkscreened on the board in the FCC photos.

The MediaTek chip model is photoshopped out of the detailed FCC internal photo of the chip but it is very likely a MT7610U.

The FCC entry also covers the Panda Wireless IGU0B which supposedly just has a different color.
