Mainboard Notes

Power Indicator Light

• Only through TYPE-C power supply and not connecting other mainboard power supplies, at least two lights 3.3V and 5V should be on
• After connecting the mainboard power supply, the mainboard power light should be on 3.3V, 5V, and VCC

Troubleshooting

Notice

• Without any external devices (drivers, limit switches, 12864, etc.)
• Only through TYPE-C power supply, at least 3.3V and 5V LEDs should be constantly lit

• If no lights are lit, it indicates a short circuit, please contact customer service
• If one of 3.3V or 5V is flashing, it indicates a short circuit, please contact customer service

Limit Switch Port

• Please note the wiring order, three-wire limit switches need to pay attention to 5V, GND, S. If connected incorrectly, it may cause damage to the mainboard
• For two-wire connections, directly connect S and GND
• PL08 and other proximity switches need to be connected with a diode on the signal port to reduce the voltage below 3.3V

Firmware

• Due to button issues, the tutorial has been updated to use Katapult firmware for firmware burning
• It is recommended to use a computer to flash the Katapult firmware and then use the Katapult firmware to burn Klipper
• BL Programming
