Troubleshooting

Important Notes

• When there are no external devices connected (drivers, limit switches, 12864, etc.)
• Powering only via TYPE-C should at least keep the 3.3V indicator constantly lit.

• If the 5V light does not turn on after connecting both the motherboard power and driver power, please contact customer service for support.

Drivers

• The motherboard supports external drivers. Wiring and Configuration Tutorial

Limit Switch Ports

• Please pay attention to the wiring order. For three-wire limit switches, ensure correct connections for 5V, GND, and S. Incorrect wiring may cause damage to the motherboard.
• For two-wire limit switches, simply connect S and GND.
• PL08 and other proximity switches require an external diode on the signal port to reduce the voltage below 3.3V.
