FAQ

If touch screen is out of work please make sure you connect the Display’s MicroUSB Port to your device (PC, Raspberry Pi, Beagle bone black etc.)
Note:

We are not sure it can work at android system due to it dose not test in android OS yet.

If you find that the screen is blur when you connect it to your device, please check the FPC cable on the back of driver board,
it may loose when it was shipping to you.
Just pull out the block of the FPC cable and put the FPC wires into it and make sure it fasten tightly and retry it again.
Please take care of this cabin cable; it’s connected to the board and sends the touch screen data to the chip on the board.
