2-Channel CAN FD HAT for Raspberry Pi

This 2-Channel CAN bus expansion HAT adds CAN 2.0 and CAN FD support to Raspberry Pi boards via the 40-pin GPIO header. It uses the MCP2517FD controller and MCP2562FD transceiver for higher data throughput. The board suits automotive devices and industrial automation where reliable CAN communication is required.

SPI interface with 120 Ω termination and isolation

Communication runs over SPI with selectable 3.3 V or 5 V logic levels set by jumper. A 120 Ω terminal resistor is configured by jumper for bus termination. Onboard electrical isolation up to 5 kV plus 500 W lightning surge, ESD and short-circuit protection limit exposure to transients. Breakout SPI control pins allow connection to other host boards such as STM32 or Arduino.

40-pin GPIO stack with jumper configuration

The HAT mounts directly on the standard Raspberry Pi 40-pin GPIO extension header. Two jumpers select operating voltage and termination, so incorrect jumper placement can prevent communication. Users must enable the SPI interface in the Raspberry Pi OS and install the appropriate kernel driver or library. No driver is included, so software setup is required before use.

Questions about this item

Which version should I choose, the 3.3V or 5V operating voltage?

The board includes an onboard voltage translator with a jumper that lets you select either 3.3V or 5V operation to match your Raspberry Pi or host controller.

What does the 500W surge protection actually stop in a real installation?

The 500W lightning surge protection clamps transient voltage spikes on the CAN lines, shielding the Raspberry Pi and connected nodes from damage during electrical disturbances.

How does the SPI interface limit the CAN FD throughput on this HAT?

The MCP2517FD controller connects via SPI, so the practical CAN FD data rate is bounded by the SPI clock speed you configure on the Raspberry Pi or host board.
