Product Description

RS485 expansion board(Raspberry Pi 4B/3B+/Zero W)

Product parameter:

  • CAN controller: MCP2515
  • Working voltage: 3.3V
  • CAN transceiver: SIT65HVD230DR
  • Fixed screw hole diameter: 3.0mm
  • 485 transceiver: SP3485
  • Product size: 65 x 30mm

Features:

  • Based on Raspberry Pi 40pinGPIO interface, it is suitable for Raspberry Pi series motherboards
  • With CAN function, CAN controller MCP2515 with SPI interface and transceiver SIT65HVD230DR are used
  • With RS485 function, UART control, half-duplex communication, automatic switching of transceiver status without program control, and SP3485 transceiver
  • On-board TVS (transient voltage suppression tube) and RS485 communication can effectively suppress surge voltage and transient peak voltage in the circuit, and prevent lightning and static electricity
  • Reserve control interface for other controllers to control
