The 2-Channel CAN bus expansion HAT, designed for Raspberry Pi, supports two CAN FD (CAN with Flexible Data-Rate) ports with a data rate of up to 8Mbps. It features multi onboard protection circuits, high anti-interference capability to assure reliable operation and make it suitable for applications in the field of automotive devices and industrial automation.

The CAN FD HAT adds CAN Bus capabilities to your Raspberry Pi, not only the original CAN 2.0 protocol, but also the CAN FD extension, with up to 8Mbps data rate, and higher data throughput.

Thanks to multiple onboard protection circuits, include 500W lighting surge, ESD, short circuit protection, and electrical isolation, it makes the communication safer and more reliable.

To support automotive and industrial applications more effectively, the board's power supply accepts an input range of 8 to 26 VDC.


  • Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards
  • Supports both traditional CAN2.0 and CAN FD protocols, up to 8Mbps data rate
  • Breakout SPI control pins, for connecting with host control boards like STM32/Arduino
  • Onboard electrical isolation, up to 5KV isolated voltage, high anti-interference capability, stable operation
  • Onboard lighting proof, ESD, short circuit protection, more safe communication
  • Onboard voltage translator, select 3.3V/5V operating voltage by jumper
  • Onboard 120Ω terminal resistor, configured by jumper


  • CAN Bus controller: MCP2517FD
  • CAN Bus transceiver: MCP2562FD
  • Communication interface: SPI (two channels independent SPI by default, swith to one channel SPI by soldering)
  • Power supply: external power input terminal, or Raspberry Pi
  • Power input terminal voltage: 8~26 VDC
  • Operating voltage: 5VDC
  • Logic level: 3.3 VDC/5 VDC
  • Dimensions: 65.0 x 56.5 mm
