CAN-Bus Shield Expansion Board for Arduino
High-Speed Automotive and Industrial CAN Networking for Microcontrollers
The CAN-Bus Shield Expansion Board adds reliable, industrial-grade Controller Area Network (CAN) communication capabilities directly to your Arduino platform. Built using the industry-standard MCP2515 CAN controller alongside an MCP2551 (or TJA1050) transceiver, this shield enables your microcontroller to send, receive, and process data on CAN networks at speeds up to 1 Mb/s. It plugs seamlessly onto Arduino Uno and Mega form factors, utilizing a high-speed SPI interface to leave remaining GPIO pins open for your sensors, displays, and actuators.
Ideal for automotive diagnostics, industrial automation, and robotics, this expansion board allows developers to read OBD-II vehicle telemetry—such as RPM, speed, engine temperature, and diagnostic trouble codes (DTCs)—or link multiple microcontrollers into a robust, noise-tolerant local network. Equipped with onboard screw terminals for easy CAN-H and CAN-L bus connections, a built-in DB9 interface, and an integrated micro-SD card slot for offline data logging, this shield provides a complete, plug-and-play hardware solution for prototyping vehicle networks and industrial control systems.
