  • Switch can turn to P3 chain side to enable P3 HUB75 output.
  • To drive one panel, connect P1 Port to your panel HUB "IN"
  • Supply Power at least 3-5A 5V to LED panel.
  • Double check your panel specifications, we only support for our type panels. Different panel specification may need revise the code.
