Seeed Studio CAN-BUS Shield V1.2

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 capability. With an OBD-II converter cable added on and the OBD-II library imported, you are ready to build an onboard diagnostic device or data logger.

The CAN-BUS shield V1.2 is the latest version with very considerable functions update. The changeable chip select pin provides an alternative pin to communication with the chip. An on board screw terminal makes it very convenient to connect CAN-H and CAN_L directly. Just like other Arduino compatible shield, we integrated the Arduino Uno headers on the shield so that you can plug the shield into Arduino Uno directly. And as an expansion board, 2 grove port is added to the board to offer more possibility with the hundreds of Grove modules.
