RS485 CAN HAT expands Raspberry Pi with two common industrial differential communication buses. The CAN interface uses MCP2515 controller over SPI for reliable vehicle and industrial CAN communication. RS485 supports Modbus and long-distance wired transmission with auto direction control. Built-in protection circuits improve stability in noisy factory environments. Terminal blocks simplify wiring to sensors, PLCs and motor drivers. It is widely used for industrial data acquisition, Modbus RTU networks, automotive CAN monitoring and remote sensor nodes. Raspberry Pi board is not included.
