Mainboard Precautions

Power Indicator Light

  • Only through TYPE-C power supply and not connected to 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, 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 always lit
  • If the 5V light does not light up after connecting the mainboard power supply and 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, S must be connected correctly, otherwise it 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 be connected with a diode on the signal port to reduce the voltage below 3.3V
