All Dingchang's Android boards with Vbyone are equipped with a backlight interface, which is used to supply backlightpower for Vbyone 4K screens. The 12V power supply current does not exceed 1.5A,and the backlight enable voltage is 3.3V.
If other voltages are required,please add an IO level conversion circuit. It should be noted that when using alarge screen of more than 19 inches or a screen with a backlight power of morethan 20W, the backlight power supply should be taken from another power board.
