I'm currently in the process of designing a wired network for home automation and have chosen CAN. I've been prototyping with the Seeed Studio shields, but for my full implementation I'll be using custom circuit boards with the same CAN controller and transceiver. My questions relate not to these chips but to general implementation of the bus in hardware.
I've been reading through documentation form Schneider Electric (here). My plan is to have simple PCBs for the taps with terminal blocks for CANH, CANL, and GND and another simple set of PCBs for bus termination. The CANH and CANL wires will be a twisted wire pair of 22 AWG hookup wire from Adafruit and will be bundled up with the ground cable in plastic spiral wire wrap.
At start the bus should only be about 10 feet long with three devices, but I'm hoping for this to be extensible. I'm aware that as I add length to the bus I may have to reduce my baud rate due to capacitance.
Is anyone here experienced with CAN bus at all and can point out any details I'm not accounting for? I'd hate to twisted together 10 feet of wire and find out I did something terribly wrong!
