Technicians often use these units as centralized hubs for collecting data from disparate machines, normalizing the signals into a format that higher-level ERP systems can consume. The platform natively supports serial communication, making it an excellent choice for Modbus RTU setups used in industrial sensor networks.

It can also serve as a gateway, translating between legacy serial devices and modern MQTT or HTTP APIs. Its low power consumption also means it can run continuously for years with minimal operational overhead, reducing the total cost of ownership significantly.
Protocol Use Case Benefit Modbus Reading sensors and controlling PLCs Industry standard for reliable data exchange MQTT Sending data to cloud brokers Lightweight messaging for IoT applications OPC UA Enterprise-level data integration Secure and platform-agnostic interoperability Building a Reliable Edge Device Reliability is non-negotiable in industrial settings where downtime equals lost revenue. General-purpose input/output (GPIO) pins provide direct access to machinery, allowing the board to read switch states, control relays, and drive actuators with precision.
