The CAN-BUS is a popular choice for industrial systems due to its long range, moderate communication speed, and reliable performance. It is often used in modern machine tools, such as for automotive diagnostics.

This CAN Bus Shield allows you to add CAN Bus capabilities to your Arduino projects using the MCP2515 controller with an SPI interface and the MCP2551 transceiver. By attaching an OBD-II converter cable and importing the OBD-II library, you can easily build an onboard diagnostic device or data logger.

Note: The headers on this product may need to be soldered by the user upon arrival. If you are unsure how to do this, you can contact info@longan-labs.cc after placing your order and we will solder the headers for you before shipping.

We have just released a new CANBed with an aluminum alloy case. If your product needs a casing, we recommend you check out this new product.

Application Ideas

  • ● Automotive diagnostic tool: By using the OBD-II converter cable and library, you can build an onboard diagnostic device that can read and interpret a variety of diagnostic information from your vehicle.
  • ● Data logger: With the ability to communicate with other devices using the CAN Bus protocol, you could use the CAN Bus Shield to build a data logger that can collect and store data from various sensors or devices.
  • ● Industrial control system: The CAN Bus Shield's compatibility with CAN 2.0 protocols makes it a suitable choice for use in industrial control systems where it can be used to communicate with and control various industrial equipment.
  • ● IoT device: By combining the CAN Bus Shield with other sensors and connectivity options, you could build an IoT device that can collect and transmit data over the CAN Bus protocol.
  • ● Home automation system: By connecting various home automation devices to the CAN Bus, you could build a home automation system that can be controlled using the CAN Bus Shield and an Arduino.
