Installation

Connect the Arduino to the LED‑Matrix

The matrix has connections on two corners — use the "IN" connection, not "OUT"

Recommended cable length: approx. 8cm

Connections:

  • V+ → VCC
  • V− → GND
  • IN → Pin 6 on Arduino
  1. Press in heat-set inserts with a soldering iron (at approx. 200°C)
  2. If a smaller Arduino was used, simply glue it to the bottom with a small dot of superglue and insert screws
  3. In SimHub, click on Arduino, add a new one, select COM port, upload, and finally go to the RGB Matrix section and choose how you want to use this display
