OverviewThe RS485 CAN HAT will enables your Pi to communicate with other devices stably in long-distance via RS485/CAN functions. Features Standard Raspberry Pi 40PIN GPIO extension header, compatible with Raspberry Pi Zero/Zero W/Zero WH/2B/3B/3B+/4B and later versions CAN function, onboard CAN controller MCP2515 via SPI interface, with transceiver SIT65HVD230DR RS485 function, controlled via UART, half-duplex communication, supports automatic TX/RX control without programming, onboard transceiver SP3485Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit for RS485 transceiving, llgthningproof & anti-electrostaticReserved control pins, allows to work with other control boards Comes with development resources and manual (examples in wiringPi/python)
