Introduction: CAN-BUS is a widely used industrial communication bus known for its long transmission distance, moderate data rate, and high reliability. It is commonly used in modern machine tools and automotive diagnostic systems. This CAN-BUS Shield features the MCP2515 CAN controller with SPI interface and the MCP2551 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 tools or vehicle data loggers. Features: - Compliant with CAN V2.0B protocol, supporting data rates up to 1 Mbps - SPI interface compatible up to 10 MHz - Fully compatible with Arduino and compatible boards - Supports standard (11-bit) and extended (29-bit) data and remote frames - Equipped with industry-standard 9-pin sub-D connector - Two prioritized receive buffers - Operating voltage: DC 5–12 V - Housing material: Plastic - Color: Black Package Includes: - 1 × CAN-BUS Shield expansion board - 5 × rows of header pins Note: Colors may vary slightly due to lighting conditions and screen settings. Dimensions are subject to a tolerance of ±1–3 cm.
