Product Description
Raspberry Pi RS485 CAN expansion board UART communication module onboard TVS supports automatic switching of transceiver statusFeatures:
Based on Raspberry Pi 40PIN GPIO interface, suitable for Raspberry Pi series motherboards
Equipped with CAN function, using SPI interface CAN controller MCP2515, with transceiver SIT65HVD230DR
It has RS485 function, uses UART control, half-duplex communication, supports automatic switching of transceiver status without program control, and the transceiver is SP3485
The 120Ω terminal resistor of the onboard RS485 and CAN interface can be enabled by setting the DIP switch.
Onboard TVS (transient voltage suppressor), RS485 communication can effectively suppress surge voltages and transient peak voltages in the circuit, and protect against lightning and static electricity
Reserved control interface to facilitate control by other controllers
Provide complete supporting information manual (providing wiringPi and Python routines)
