Arduino MKR CAN Bus Shield AFX00005

The Arduino MKR CAN Bus Shield adds CAN 2.0B connectivity to any MKR family board, enabling direct communication with automotive and industrial CAN networks. Based on the Microchip MCP2515 controller and MCP2551 transceiver, it delivers reliable data exchange at up to 1 Mbit/s through a 3-pin screw terminal. The shield includes a jumper-selectable 120 Ohm termination resistor and LED indicators for power, TX, and RX, making it a practical choice for diagnostics, robotics, and IoT projects.

Highlights

• CAN 2.0B protocol support at up to 1 Mbit/s
• Stackable MKR form factor with SPI host interface
• Selectable 120 Ohm termination via jumper
• LED indicators for power and CAN activity
• Compatible with the Arduino CAN Library

In daily use

Connect the shield to your MKR board, wire CAN H, CAN L, and GND to the bus, and configure the termination jumper if needed. The Arduino CAN Library provides ready-made examples for sending and receiving frames, so you can focus on your application logic rather than low-level protocol details.
