MCP2515 CAN Bus Shield Board w/ SPI & Sub-D Connector

Description

The MCP2515 CAN Bus Shield is an essential expansion module designed to bring Controller Area Network (CAN) capabilities to your Arduino or Freaduino development board. Leveraging the MCP2515 CAN controller, which communicates via a high-speed SPI interface (up to 10 MHz), and the MCP2551 CAN transceiver, this shield enables reliable data exchange over a common industrial bus, critical for applications requiring long travel distance, medium communication speed, and high reliability.

This shield fully supports CAN V1.2 B at speeds up to 1 Mb/s, handling both standard (11-bit) and extended (29-bit) data and remote frames, making it versatile for various protocols. Its industrial-standard 9-pin sub-D connector ensures secure and robust physical connections, commonly found in modern machine tools and as the automotive diagnostic bus (OBD-II). By integrating this shield with an OBD-II converter cable and the appropriate library, developers can readily build onboard diagnostic devices or powerful data loggers for vehicle monitoring and analysis.
