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
