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