Product Usage Instructions

Connect the panel power by setting the PNL_PWR1 jumper to the
desired voltage level (1-2 for +3V, 2-3 for +5V).
Adjust the backlight volume by using the BLT_VOL1 jumper, which
has various control signals.
Connect a speaker to the SPEAKER1 header. The pin configuration
for the speaker is as follows:
Pin Signal Name
1 SPK L-
2 SPK L+
3 SPK R+
4 SPK R-
Connect a CPU fan to the CPU_FAN1 connector, which provides
+12V power.
Connect SATA devices by using the SATA_PWR1 connector for power
and the SATA3_0 connector for data.
Connect a MIPI device to the MIPI1 connector, which has various
signal pins for data transmission.
Install DDR4 memory modules into the DDR4_A1 slot (supports
DDR4 only).
Connect a VGA display to the VGA1 connector.
Connect front panel audio devices to the HD_AUDIO1 header,
which has various signal pins for audio input and output.
Adjust the voltage level for backlight power control by setting
the BLT_PWM2 jumper to 1-2 for 3V level (
