RC Trailer Control Module – Slave Electronics Board

Trailer Control Module – RC Model Slave Controller

Lighting, Servo & Motor Control for RC Trailers

The Build Your RC Trailer Control Module is a dedicated RC trailer control module designed to control trailer lighting, servo functions, and motorized accessories. This compact electronics board operates as a slave controller that works together with the Build Your RC control board.

When connected to the master control board, the trailer module receives commands and executes lighting effects, servo movements, and motor control functions. This creates a clean and modular electronics architecture for advanced RC model trailer systems.

The module is ideal for builders who want to add realistic lighting systems, servo functions, and motor control to scale trailers, robotics platforms, or custom electronics builds.
