I am designing a CAN bus for a light electric vehicle, likely using an Arduino CAN bus shield or similar.
Using a single D-sub cable it's obvious that two devices could be connected together. The system I'm designing will have multiple CAN nodes and so I'm curious of the best way to achieve this.
I think the best option is to use a simple D-sub splitter. This will keep the branch from the main CAN bus line less than 30 cm as per specifications and thus minimising interference.
The only other answer I can think of is to hack the board a little and wire up another connecter in parallel to the existing one.
Will using a simple splitter cause me any issues? If so, can I solve them? If not, is there another easy way I can use these boards to interface with a CAN bus with multiple devices using D-sub cabling?
