Motherboard Notes

Power Indicator Lights

• At least two lights (3.3V and 5V) should illuminate when only powered via TYPE-C without connecting other motherboard power sources
• After connecting the motherboard power, the lights for 3.3V, 5V, and VCC should illuminate

Troubleshooting

Note

• Without any external devices connected (drivers, limit switches, 12864 displays, etc.)
• Only when powered via TYPE-C, the 3.3V light should remain steadily on

• If the 5V light does not illuminate after connecting the motherboard power and driver power, please contact customer support

Drivers

• The motherboard supports external drivers Wiring and Configuration Guide

Limit Switch Ports

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