Waveshare Rs485 Can Hat For Raspberry Pi

Yes, this board support both RS485 and CAN, bidirectional communication. You can use both the standards/protocols at the same time because each of them uses different peripherals for communication. CAN controller uses SPI while RS485 uses UART from Raspberry Pi.


  1. Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards
  2. CAN function, onboard CAN controller MCP2515 via SPI interface, onboard transceiver SN65HVD230
  3. RS485 function, controlled via UART, half-duplex communication, supports automatic TX/RX control without programming, onboard transceiver SP3485
  4. Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit for RS485 transceiving, lightning-proof & anti-electrostatic
  5. Reserved control pins, allows working with other control boards
  6. Comes with development resources and manual (examples in wiringPi/python)
