CAN-BUS is a common industrial bus because of its long travel distance, medium communication speed and high reliability.
It is commonly found on modern machine tools and as an automotive diagnostic bus. This CAN-BUS Shield adopts MCP2515 CAN Bus controller with SPI interface and MCP2551 CAN transceiver to give your Arduino/Seeeduino CAN-BUS capibility. With an OBD-II converter cable added on and the OBD-II library imported, We should ready to build an onboard diagnostic device or data logger.
