 This guide is tested with the LCD-15.6TS (with ETT5003U controller), distributed by Olimex LTD. The setup included LCD-OLinuXino-15.6-FHD and A20-OLinuXino-MICRO.
-Important: for the hardware connection you would need to provide 12V to the controller via the touchscreen display using the 4-pin molex connector (yellow wire = 12V input; black wires = GND). A free USB port is also required. The powering to the touchscreen is deliver through a standard 4-pin molex connector.

 Establish the hardware connections and set the LCD properly (if using our displays remember to execute change_display.sh). Then in order to get the touchscreen working under the official Linux image do the following:
