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 * Comes with development resources and manual (examples in wiringPi/python) Resources * Product Wiki Specifications * Operating voltage: 3.3V * CAN controller: MCP2515 * CAN transceiver: SN65HVD230 * 485 transceiver: SP3485 * Dimension: 65mm x 30mm * Mounting hole size: 3.0mm Pinouts PIN RPI (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**), high for TX, low for RX **some soldering is required to enable manual control https://elecena.pl/product/22719105/rs485-can-hat-for-raspberry-pi 2023-03-07 https://elecena.pl/product/22719105/rs485-can-hat-for-raspberry-pi 2023-12-27 https://elecena.pl/product/22719105/rs485-can-hat-for-raspberry-pi 2024-09-19 https://elecena.pl/product/22719105/rs485-can-hat-for-raspberry-pi 2024-11-29 https://elecena.pl/product/22719105/rs485-can-hat-for-raspberry-pi 2024-11-30 https://elecena.pl/product/22719105/rs485-can-hat-for-raspberry-pi 2025-08-05 https://elecena.pl/product/22719105/rs485-can-hat-for-raspberry-pi 2025-11-28 https://elecena.pl/product/22719105/rs485-can-hat-for-raspberry-pi 2025-11-29
