LVDS Voltage Selection (JP1 and JP2)

The board supports voltage selection for flat panel displays. Use these jumpers to set
LVDS connector (CN8) pin 1~6 VCCM to +3.3V, +5V or +12V. To prevent hardware
damage, before connecting please make sure that input voltage of flat panel is correct.

Auto Power On (JP4)

If this jumper is enabled for power input, the system will be automatically power on
without pressing soft power button. If this jumper is disabled for power input, it is
necessary to manually press soft power button to power on the system.

LVDS Brightness Control Mode Setting (JP5)

This jumper enables you to select PWM or voltage control mode for inverter connector
(CN10). These two control modes are for adjusting the brightness of LVDS panel.
