The Arduino CAN BUS (OBD) Shield with the MCP2515 controller is an expansion board that lets your Arduino read and send messages over a CAN bus network. It plugs straight onto compatible Arduino boards and is a popular choice for car diagnostics (OBD), automation electronics, robotics, and student or hobby projects that need reliable serial communication between devices.
Key features
- Built around the well-known MCP2515 CAN controller for standard CAN bus communication.
- Designed as an Arduino shield, so it stacks onto compatible Arduino boards with minimal wiring.
- Suitable for OBD and general CAN network reading and message sending.
- Works well with widely available open-source CAN libraries and example sketches.
Typical uses
- Reading vehicle data and building DIY OBD diagnostic tools.
- Automation, robotics, and sensor networks that share a single CAN bus.
- Electronics learning, prototyping, and graduation projects.
How to choose / tips
- Confirm your Arduino board is compatible with shield-style stacking before ordering.
- Pick a tested CAN library that matches the MCP2515 to speed up your setup.
- Double-check your CAN bus wiring and node settings for stable communication.
