RS485 CAN HAT for Raspberry Pi 4B/3B+/3B/2B/B+/A+/Zero/Zero W/WH, with standard Raspberry Pi 40PIN GPIO extension 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 suppress surge voltage and transient spike voltage in the circuit for RS485 transceiving, lightningproof & anti-electrostatic
Reserved control pins, allows to work with other control boards, comes with development resources and manual (examples in wiringPi/python)
