Mainboard Precautions

Power Indicator Light​

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

Troubleshooting​

Important Notes
  • Under conditions with no external devices connected (drivers, limit switches, 12864, etc.)
  • When powered only via TYPE-C, at least the 3.3V light should be constantly on.
  • If the 5V light does not turn on after connecting the mainboard power supply and driver power supply, please contact customer service for after-sales support.

Drivers​

  • The mainboard supports external drivers. Wiring and Configuration Tutorial

Limit Switch Ports​

  • Please pay attention to the wiring order. For three-wire limit switches, note the connections for 5V, GND, and S. Incorrect wiring may cause damage to the mainboard.
  • 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 to below 3.3V.
