A standard A13 based, Q8 style device with separate UART pads.
This motherboard seems to have been used in several rebadges, and will come with different batteries, different cameras, and perhaps different Wifi modules and last but not last, this form factor is used in A23 and A33 tablet.
Identification
The back of the PCB reads Q8-V12., but google reveals that there are highly similar PCBs where a different name is silkscreened on the backside.
For the Point Of View Mobii 703, you will find, in android, under Settings->About Tablet:
- Model Number: POV_TAB_P703(V1.0)
- Build Number: nuclear_evb-eng 4.1.1 JRO03C 201311126 test-keys
The Build string is not helpful, as "nuclear_evb" just means A13 evaluation board.
To properly identify this device, open up the case, detach the motherboard, and look at the printing on the other side.
