Isolated Dual RS-485 (Modbus) Industrial HAT++ for Raspberry Pi
Datasheet Schematic 3D Model Layout
Modbus over RS-485 enables robust long-distance multi-drop communication and is a well-established, future-proof industrial communication standard.
This HAT provides two fully independent, galvanically isolated RS-485 interfaces with automatic direction detection and, as part of the BE-IIS HAT++ ecosystem, is stackable with other HATs from the portfolio for seamless system expansion and simplified system integration.
