Waveshare RS485 CAN HAT for Raspberry Pi

The RS485 CAN HAT will enable your Pi to communicate with other devices (e.g. the Huvud Controller Board) via RS485/CAN over long distances.


  • Raspberry Pi connectivity, compatible with Raspberry Pi Zero/Zero W/Zero WH/2B/3B/3B+/4B
  • CAN function, onboard CAN controller MCP2515 via SPI interface, onboard transceiver SN65HVD230
  • RS485 function, controlled via UART, half-duplex communication, supports automatic TX/RX control without programming, onboard transceiver SP3485
  • Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltages and transient spike voltages in the circuit for the RS485 transceiver
  • Reserved control pins, allows to work with other controller boards
  • Comes with development resources and manual (examples in wiringPi/python)


  • Operating voltage: 3.3V
  • CAN controller: MCP2515
  • CAN transceiver: SN65HVD230
  • 485 transceiver: SP3485
  • Dimension: 65mm x 30mm
  • Mounting hole size: 3.0mm
