CAN Bus Shield Revision... Looking for Ideas

What about place for optional 2 x RJ45 connectors? For Model Railroading, NMRA (the powerful US Model Railroading Association) is setting NMRAnet features for a standardized bus based on a CAN-bus with OpenLCB protocols and specs, including 2 RJ45 connectors in each board.

I will keep this in mind. I have a few railfans friends.

But main feature to be incorporated, as you pointed before, should be the possibility to piggiback on an Arduino two or more Shields using SPI transmission (that is, your CAN Shield plus another other shield), thus allowing Arduino to have two different SS pins to able / dissable one or the other shield according to which one should communicate with Arduino at a due moment.

You can do that with the library on my github as well as use more than one CAN shield on the same Arduino. I had a CAN-Shield setup with an Ethernet shield a few days ago. Was taking received CAN data, encapsulating it inside a UDP packet, and sent it to of my Linux boxes. I made a Perl script to listen to the UDP port and display it on the console. I also have a breadboard with two MCP2515s connected to an ATmega328 that has been transferring data on one CAN bus to the other. Its been running for a good week or more now.
