Product Description

The CAN Bus Plus RS485 CAN HAT adds serial networking options to your Raspberry Pi Zero/Zero W/Zero WH/2B/3B/3B+.

The onboard CAN Bus port utilizes the Microchip MCP2515 CAN controller, accessible per SPI interface, in combination with the SN65HVD230 CAN transceiver.

The RS485 port is controlled via the RPi's UART using the SP3485 transceiver.

The combination of CAN Bus and RS485 capabilities supports applications such as connecting a CAN Bus network with a Modbus device or a CAN-to-Modbus gateway. The RS485 port can also be used to monitor (listen-only) SAE J1708 data traffic and convert it to Controller Area Network.

Features

  • Raspberry Pi connectivity, compatible with Raspberry Pi Zero/Zero W/Zero WH/2B/3B/3B+
  • CAN function, onboard CAN controller MCP2515 via SPI interface, with transceiver SN65HVD230
  • RS485 function, controlled via UART, half-duplex communication, with transceiver SP3485
