Motherboard Precautions

Power Indicator​

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
  • Under the condition of no external devices connected (drivers, endstops, 12864, etc.)
  • When powered only via TYPE-C, at least the 3.3V light should remain on
  • If the 5V light does not illuminate after connecting the motherboard power and driver power, please contact customer service for after-sales support

Driver​

  • The motherboard supports external drivers. Wiring and Configuration Tutorial

Endstop Ports​

  • Pay attention to the wiring sequence. For three-wire endstops, note the 5V, GND, and S pins; incorrect connection may damage the motherboard
  • For two-wire endstops, connect directly to S and GND
  • For PL08 and other proximity switches, an external diode must be added at the signal port to reduce the voltage to below 3.3V
