Introduction: CAN-BUS is a widely used industrial communication bus known for its long transmission distance, medium data rate, and high reliability. It is commonly used in modern machinery and automotive diagnostic systems. This CAN-BUS Shield features the MCP2515 CAN controller with SPI interface and the MCP2551 CAN transceiver, enabling CAN-BUS functionality for Arduino and Seeeduino boards. When paired with an OBD-II converter cable and compatible OBD-II library, it supports development of onboard diagnostic tools or vehicle data loggers. Features: - Complies with CAN V2.0B standard, supporting data rates up to 1 Mbps - SPI interface compatible up to 10 MHz - Fully compatible with Arduino and Seeeduino platforms - Supports both standard (11-bit) and extended (29-bit) data and remote frames - Equipped with industrial-standard 9-pin sub-D connector - Includes two prioritized receive buffers - Operating voltage: DC 5–12 V - Housing material: Plastic - Color: Black Package Contents: - 1 × CAN-BUS Shield Expansion Board - 5 × Rows of header pins Note: Actual product color may vary slightly due to screen settings and lighting conditions.
