Introduction: CAN-BUS is a widely used industrial communication bus known for its long transmission distance, medium communication speed, and high reliability. It is commonly used in modern machine tools and as an automotive diagnostic bus. This CAN-BUS Shield features the MCP2515 CAN Bus controller with SPI interface and the MCP2551 CAN transceiver, enabling CAN-BUS functionality for Arduino and Seeeduino platforms. When paired with an OBD-II converter cable and the OBD-II library, it supports development of onboard diagnostic devices or data loggers. Features: - Compliant with CAN V2.0B protocol, up to 1 Mbps - SPI interface up to 10 MHz - Fully compatible with Arduino and Seeeduino - Supports 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: DC 5–12 V - Housing material: Plastic - Color: Black Package Includes: - 1 × Expansion Board - 5 × Rows of pins Note: The actual product color may vary slightly due to monitor settings and lighting conditions.
