PICO121 AMD G-Series Embedded SoC Pico-ITX Board
Board and Pin Assignments 13
2.4.1 LVDS +12V Voltage Selection (JP1) (Optional)
The board supports voltage selection for flat panel displays. Use JP1 to set LVDS
connector (CN8) pin 1~6 VCCM to +12V. To prevent hardware damage, before
connecting please make sure that the input voltage of flat panel is correct.
2.4.2 Auto Power On (JP2)
If this jumper is enabled for AC power input, the system will be automatically power on
without pressing soft power button. If this jumper is disabled for AC power input, it is
necessary to manually press soft power button to power on the system.
Note
This function is similar to the feature of power on after power failure,
which is controlled by hardware circuitry instead of BIOS.
2.4.3 LVDS +3.3V/+5V Voltage Selection (JP3)
The board supports voltage selection for flat panel displays. Use JP3 to set LVDS
connector (CN8) pin 1~6 VCCM to +3.3V or +5V. To prevent hardware damage, before
connecting please make sure that the input voltage of flat panel is correct.
2.4.4 LVDS Brightness Control Mode Setting (JP4)
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.
