The “N” in CAN stands for network, after all. The trick is to create a device ID for each desired CANSerial interface, which is done in his library using the usual Arduino setup step.

In the middle are options like this, which handle the CAN interface and are controlled via SPI (such as from an Arduino or Raspberry Pi).

An Arduino can interface with them but the code is a bit tricky and to get a webpage of it starts costing alot. You can get a standalone server here but I have no idea how well they work.

The new IXXAT USB-to-CAN V2 interface connects over USB 2.0 at 480 Mbps, enabling very high data throughput with minimum latency and lower power consumption.

You can’t screw up Arduino’s new DIY electronics kit The $87 Plug and Make Kit includes an Arduino microcomputer, electronic components, and tutorials for building several IoT devices.

An Arduino is a microcontroller — a single board designed to control something and perform a specific task. Unlike a Raspberry Pi, you won't find anything resembling an operating system here ...
