Green Arduino shield board with 9-pin D-sub connector and SD card slot

Seeed Studio

Seeed Studio CAN FD Shield for Arduino

SKU CH-W626-NK5VT

Arduino-compatible shield adds CAN-FD and CAN 2.0 connectivity with industrial 9-pin sub-D, high-speed SPI and selectable OBD-II pinouts

  • TypeSensors
  • CAN-FD and CAN 2.0 support for vehicle diagnostics up to 5 Mb/s
  • Industrial 9-pin sub-D connector fits standard CAN equipment
  • 10 MHz SPI interface enables fast data logging
  • Selectable OBD-II or standard pinouts with adjustable CS and INT pins
  • Built-in SD card slot stores logged data directly on the shield

Arduino CAN-FD extension board

This shield adds CAN-BUS capability to Arduino boards using the MCP2517FD controller and SIT1042T transceiver. It supports both CAN-FD and CAN 2.0 protocols for vehicle diagnostics and industrial monitoring. An onboard SD card slot enables direct data logging without external storage.

Industrial 9-pin sub-D and SPI

The industrial-standard 9-pin sub-D connector fits existing CAN cabling in automotive and factory environments. Selectable OBD-II and standard CAN pinouts let one board serve both vehicle and machine networks. The 10 MHz SPI interface provides headroom for high-rate message streams, while adjustable chip-select and INT pins prevent conflicts with other shields.

CE and FCC certified operation

The board carries CE and FCC certification for electromagnetic compatibility in regulated installations. Power is drawn from the Arduino host through the standard pin headers, keeping wiring simple. An optional aluminum alloy case is available for mechanical protection in harsh cabinets or vehicle compartments.

Questions about this item

Will the shield's 10 MHz SPI interface work with my older Arduino Uno?

Yes, the 10 MHz SPI bus is fully compatible with the Arduino Uno's hardware SPI pins and clock capabilities.

How can I confirm the MCP2517FD controller and SIT1042T transceiver are communicating correctly after wiring?

Run a standard CAN-FD loopback sketch; successful transmission and reception of frames at up to 5 Mb/s proves the link is healthy.

Does the box include the industrial 9-pin sub-D cable and an aluminum case, or must I buy them separately?

The shield ships with the board and pin headers only; the sub-D cable and aluminum alloy case are optional extras.
