Steering Servo connection

Steering Servo PWM cable connection

This connection between the Steering servo and the PDB is pre-wired on the lower chassis but is shown here for reference.

Note that the PWM control signals are only passed through the PDB and XDHP connector and actually originate at the MR- CANHUBK344. +5V Power for the servo does get injected by the PDB though.

The image illustrates how a servo motor is connected to the PDB (Power Distribution Board). It shows three distinct wires: the red wire is +5V positive voltage supply, the brown wire is the ground connection, and the yellow wire carries the control RC-PWM signal from the microcontroller (MR-CANHUBK344).

As shown in the images, the correct orientation of the Servo wire is with the Yellow wire toward the short edge of the PDB. The Servo will NOT be damaged if this connection is reversed, it will simply fail to move.
