Introduction: 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 ceiver to give your FOR Arduino/FOR Seeeduino CAN-BUS capibility. 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.<br><br>Features: Implements CAN V2.0B at up to 1 Mb/s SPI Interface up to 10 MHz Ariduino/ Freaduino Completely compatible Standard (11 bit) and extended (29 bit) data and remote frames Industrial standard 9 pin sub-D connector Two receive buffers with prioritized message storage Operating voltage: DC5-12V Material: Plastic colour: black<br><br>Package Contents: 1 x Expansion Board 5 x rows of pins<br><br>Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
