Quick Setup

• You can leave the RTC and battery for beginning, it not necessary to drive the RGB matrix panel.
• 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.
