This is a 2-Channel CAN bus expansion HAT designed for Raspberry Pi, supports CAN FD (CAN with Flexible Data-Rate), the speed is higher than the traditional 1Mbps of CAN2.0, features multi onboard protection circuits, high anti-interference capability, and stable operation. It suits for fields such as automotive devices or industrial automation.


  • 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
  • Comes with development resources and manual (examples for Raspberry Pi/Arduino)


  • CAN controller: MCP2517FD
  • CAN 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: DC 8~26V
  • Operating voltage: 5V
  • Logic level: 3.3V/5V
  • Dimensions: 65.0 x 56.5 mm
