I'm a little confused on how to lay out CANBus wiring in a project I am working on. Everything I read talks about the CANBus having 'stubs' that need to be less than a certain length. I don't know how this works in practice.
I want my individual modules (PCB's) to have a 2 x 4 way PCB to wire connectors (5V, GND, CAN-H and CAN-L) in parallel to allow the daisy chaining of the CANBus. I don't see how this would achieve the design as per above diagram. The above diagram tells me I would need two main bus wores that run around the project with 'stubs' somehow connected to these bus wires. I would then only have a single 4 way connector on each PCB that would connect to the 120 Ohm terminated CANBus. How should this be done? Can I daisy chain from each PCB with 2 x 4 way connectors?
