Waveshare RS485 CAN HAT for Raspberry Pi

Waveshare RS485 CAN HAT for Raspberry PiThe Waveshare RS485 CAN HAT for Raspberry Pi will enable your Pi to communicate with other devices (e.g. the Huvud Controller Board) via RS485/CAN over long distances.FeaturesRaspberry Pi connectivity, compatible with Raspberry Pi Zero/Zero W/Zero WH/2B/3B/3B /4BCAN function, onboard CAN controller MCP2515 via SPI interface, onboard transceiver SN65HVD230RS485 function, controlled via UART, half-duplex communication, supports automatic TX/RX control without programming, onboard transceiver SP3485Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltages and transient spike voltages in the circuit for the RS485 transceiverReserved control pins, allows to work with other controller boardsComes with development resources and manual (examples in wiringPi/python)SpecificationsOperating voltage: 3.3VCAN controller: MCP2515CAN transceiver: SN65HVD230485 transceiver: SP3485Dimension: 65mm x 30mmMounting hole size: 3.0mmPinout:PINRaspberry Pi (BCM)DESCRIPTION3V33V33.3V PowerGNDGNDGroundSCKP11 / SCLKSPI clock inputMOSIP10 / MOSISPI data inputMISOP9 / MISOSPI data outputCSP8 / CE0SPI chip selectionINTP25InterruptRXDP15 / RXDRS485 UART receiveTXDP14 / TXDRS485 UART transmitRSEP4RS485 TX/RX control (auto control by default, some soldering is required to enable manual control), high for TX, low for RXMore Resources in the Waveshare wikiPackage ContentRS485 CAN HATRPi screws pack (2pcs)
