No driver in sunxi-3.4, patch can be found on our mailinglist.

Adding a serial port

Wexler TAB 7200 UART pads.

Device disassembly

Careful insert your plastic tool in the space between the USB HOST port and the back cover. Then, gently move the tool towards the camera, and you should soon hear the clips popping. Move the plastic tool from edge to edge, until the back cover comes off.

Locating the UART

There are some small pads on the bottom of the board, near the SoC. Solder on some wires according to our UART howto.
