Motherboard Precautions

Power Indicator Light​

Loading...
  • When powered only via TYPE-C without connecting other motherboard power sources, at least two lights should be on: 3.3V and 5V.
  • After connecting the motherboard power supply, the motherboard power indicator lights should show 3.3V, 5V, and VCC.

Troubleshooting​

Note
  • When no external devices are connected (drivers, limit switches, 12864 display, etc.)
  • When powered only via TYPE-C, the 3.3V light should remain constantly on.
  • If the 5V light does not illuminate after connecting the motherboard power supply and driver power supply, please contact customer service for after-sales 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, be careful with the 5V, GND, and S wires. Incorrect wiring may damage the motherboard.
  • For two-wire limit switches, simply connect S and GND.
  • For PL08 and other proximity switches, an external diode must be connected at the signal port to reduce the voltage to below 3.3V.
