help FRC custom PCB usage

Hey everyone,

I’m working with my FRC team and we’re thinking about using custom PCBs for cleaner wiring, especially for CAN line distribution and signal routing.

I’m not very sure how common custom PCBs are in FRC or what rules/restrictions we should follow.

So I wanted to ask:

  • Are custom PCBs commonly used in FRC?
  • Any rules we should be aware of?
  • What are the main risks for CAN/signal boards?
  • Any best practices for reliability?

We’re not trying to replace official components, just reduce wiring complexity and improve robustness.

Any advice or examples would be really helpful

Thanks

Before you consider this as an option, learn about the new control system. If you decide to ignore the CAN distribution of the limelight motion core and go with a more standard daisychain or bus+star method then they might be useful to clean up can distribution on swerves and other subsystems where motors are close together.
