  • When powered only through TYPE-C without connecting other mainboard power, at least two lights should be on: 3.3V and 5V
  • After connecting the mainboard power, the mainboard power indicator lights should be on: 3.3V, 5V, 12V

Troubleshooting​

NOTICE
  • With no external devices connected (drivers, endstops, 12864, etc.)
  • Powered only through TYPE-C, at least 3.3V and 5V LEDs should remain on
  • If 3.3V and 5V are not on, please check the mainboard 5V jumper
  • If the issue persists after replacing the jumper, and Type-C power supply is confirmed to be normal, please contact customer service
  • If one of the 3.3V or 5V lights is blinking, it indicates a chip short circuit, and you need to contact customer service
