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 Specifications CAN controller: MCP2515 CAN transceiver: SN65HVD230 485 transceiver: SP3485 Mounting hole size: 3.0mm Operating Voltage: 3.3V Mounting hole size: 3.0mm Dimensions: 65mm x 30mm Pinouts PIN Raspberry Pi (BCM) DESCRIPTION 3V3 3V3 3.3V Power GND GND Ground SCK P11 / SCLK SPI clock input MOSI P10 / MOSI SPI data input MISO P9 / MISO SPI data output CS P8 / CE0 SPI chip selection INT P25 Interrupt RXD P15 / RXD RS485 UART receive TXD P14 / TXD RS485 UART transmit RSE P4 RS485 TX/RX control (auto control by default, some soldering is required to enable manual control), high for TX, low for RX Specs and Docs PDF DatasheetPDF Datasheet:99tech.com.au/m/rpi-hat-rs485-can_datasheet.pdf PDF SchematicsPDF Schematics:99tech.com.au/m/rpi-hat-rs485-can_schematic.pdf Package Includes 1 x Raspberry Pi Hat2 x Screws [mx_insert-post-ebay slug="ebay-t-default"] SKU: RPI1-001 Categories: Pi Hats & Plates, Raspberry Pi, Serial Comms Modules Tags: can-bus, raspberry, rs485
