How It Works

The Air780E board connects to a compatible 4G cellular network through a SIM card and antenna. A host microcontroller or onboard processor communicates with the cellular module through the available serial interface.

Once connected to the network, the board can transmit and receive information over the cellular network, allowing a device to communicate with a remote server or IoT platform even when Wi-Fi is unavailable.

For example, a sensor system can collect temperature data and use the Air780E to send the readings to a remote server. Similarly, a GPS-enabled tracking device can periodically transmit its location over the cellular network.

Typical Applications

4G IoT devices
GPS tracking systems
Vehicle and asset tracking
Smart agriculture
Remote sensor monitoring
Industrial monitoring
Remote equipment monitoring
Smart-home systems
Security and alarm systems
Telemetry and data logging
Remote notification systems
Robotics and automation projects

Advantages

The Air780E Mini development board makes 4G Cat.1 connectivity easier to incorporate into prototypes and electronic products. Its compact size is useful where PCB space is limited, while the cellular connection allows devices to operate over a wide geographical area rather than being restricted to a local Wi-Fi network.
