Industrial Shields GateBerry Raspberry Pi-Based Industrial Gateway

The GateBerry gateway is fully compatible with all Raspberry Pi 4 models, including the 1GB, 2GB, 4GB, and 8GB variants. It is designed to host the Raspberry Pi 4 compute module within its industrial enclosure, providing the necessary power regulation and interface connections. Ensure you use a Raspberry Pi 4, as earlier models may not fit or have compatible pinouts for the carrier board.

The RS-485 and CAN interfaces are accessible via the Linux serial ports (e.g., /dev/ttyAMA0 for UART). Configuration involves enabling the appropriate overlays in the Raspberry Pi OS config.txt file and setting the correct baud rates using terminal commands or Python scripts. For CAN bus, you'll need to load the CAN kernel module and configure the bit timing using the ip link set command. Detailed wiring and software setup guides are provided in the Industrial Shields documentation.

The GateBerry runs a standard Linux distribution (Raspberry Pi OS), supporting open-source platforms like Node-RED for visual programming, Mosquitto MQTT broker for messaging, and Python/C++ for custom applications. It can function as a Modbus TCP gateway, a data logger to cloud services (AWS IoT, Azure), or a local edge controller. The absence of licensing fees allows full customization for industrial automation, SCADA, and remote monitoring projects.

The gateway requires a 12–24V DC power supply and consumes between 20W (minimum) and 30W (maximum), including the Raspberry Pi and interface circuits. The integrated uninterruptible power supply (UPS) uses a supercapacitor or battery backup to provide temporary power during main supply interruptions, allowing for a graceful shutdown or continued operation for a short duration. This protects data integrity and prevents filesystem corruption in critical 24/7 industrial environments.
