Mainboard Precautions

Power Indicator Light

• When powered only through TYPE-C without connecting other mainboard power sources, at least two lights, 3.3V and 5V, should be on.
• After connecting the mainboard power source, the mainboard power light should illuminate 3.3V, 5V, and VCC.

Troubleshooting

Notice

• In the absence of any external devices (drivers, limit switches, 12864, etc.)
• When powered only through TYPE-C, the 3.3V light should remain constantly lit.

• If the 5V light does not illuminate after connecting the mainboard power and driver power, contact customer service for assistance.

Driver

• The mainboard supports external drivers Wiring and Configuration Tutorial

Limit Switch Port

• Pay attention to the wiring sequence. For three-wire limit switches, if the 5V, GND, and S are connected incorrectly, it may cause damage to the mainboard.
• If using a two-wire connection, connect S and GND directly.
• PL08 and other proximity switches require an external diode on the signal port to reduce the voltage to below 3.3V.
