The RS485 CAN HAT will enable your Raspberry Pi to communicate with other devices stably in long-distance via RS485/CAN functions.


  • Standard Raspberry Pi 40-pin GPIO header
  • 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 voltage and transient spike voltage in the circuit for RS485 transceiving, lightning-proof & anti-electrostatic
  • Reserved control pins, allows working with other control 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
