HI,
I have created artwork in Eagle for a CANbus board that will work with any SPI interface as a slave device.
The board is double sided, uses DIP ICs and is intended to allow you to duplicate it for many nodes.
Aside from the RS-485 signals, there is a route provided to allow one node to be the source of another node's power. Each node has it's own regulated power and this can in turn be used to provide the ZX-24 with regulated +5 or alternatively the ZX-24 could use unregulated 9 volts.
Anyway, it is yours for the asking. If someone wants to have a profession board manufacture do a run, I would like to add my quantity to the order.

I went ahead and had 25 of these CANbus controller boards made in China. I just got them back and assembled a half dozen. They are quite stable and work well with any microprocessor that can provide Shiftin and Shiftout commands for the SPI interface.I will sell the for $5 each plus postage. This is not a real business, I just merely want to recoup my cost and have other to talk with about using CANbus.
My intended purpose is home automation. You can have 60 nodes and distances of 5000 feet.
