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 lit
• After connecting the mainboard power supply, the mainboard power light should light up 3.3V, 5V, and VCC

Problem Solving

Notes

• In the absence of any external devices (drivers, limit switches, 12864, etc.)
• Only through TYPE-C power supply, 3.3V will be constantly lit

• If the 5V light does not light up after connecting the mainboard power supply and the driver power supply, please contact customer service

Driver

• The mainboard supports an external driver Wiring and Configuration Tutorial

Limit Switch Port

• Please pay attention to the wiring order. For three-wire limit switches, note that 5V, GND, and S must not be connected incorrectly, as this may cause damage to the mainboard.
• If it is a two-wire connection, just connect S and GND directly
• PL08 and other proximity switches need to have a diode connected to the signal port to reduce the voltage below 3.3V
