Wiring RGB LED (PDB V0)

Wiring instructions will be demonstrated using images and GIFs for clearer visualization of the process.

Introduction

The RGB LEDS communicate using a modified SPI type that is unidirectional. The power for the LEDs is supplied by the PDB, and the SCL SDA lines attach to a SPI port on the MR-CANHUBK344

RGB LED wiring

You need to have mounted first the LED lights and covers. This step has been explained in this section: #assemble-led-light-and-covers

First, we'll show hot to connect the LEDs cables from the LEDs panels to the PDB and the MR-CANHUBK344.

Cables needed for the connection

• Use the 4-pin cable with a protective covering to connect from the front to the rear LED assembly ends.

• Connect the rear LED to the PDB (Power Distribution Board) and the MR-CANHUBK344.

The following image shows the LED lights setup with the left side representing the rear and the right side indicating the front of the car.

The remaining pin is this one:

That must be connected on the following pin of the MR-CANHUBK344:

If you have correctly followed these steps the wiring setup of the LEDs cables should be finished.
