The Seeed Studio CAN-Bus Shield is a module based on the CAN MCP2515 controller and the MCP2551 transceiver. This card module can be simply plugged into an Arduino module to allow it to communicate via the CAN bus or ODB-II. This Shield has a micro-SD card reader communicating via the SPI bus. The CAN bus is an industrial bus commonly used because it allows long-distance communication without compromising on communication speed and its reliability.
