= Tips, Tricks, Caveats =

FEL mode
There is an extra button on the PCB which can be pushed via small hole on the device's right side, in the middle before the grill. Push it during power up and it will enter into FEL mode.

Camera
Some of the early models have OmniVision OV5640 camera. More recent models come with the Samsung S5K4EC, for which no driver is currently available.

= Adding a serial port (voids warranty) =

Device disassembly
The device is held together with three smalls screws and some plastic clips. Unscrew the three screws (one is under the QC label, this is slightly bigger then the rest), and a bit slide the bottom cover to the right (towards the two screw hole). This will unclip the plastics and you can easily detach them.

The PCB held in place by two screws on the top casing.

Locating the UART
The UART pads can be found between the SoC and USB OTG connector. Just solder on some wires according to our UART howto. Be careful though, as the pads are tiny.
