DF Robot Air780EU 4G CAT1 IoT Module - USB & Serial

The DF Robot Gravity: Air780EU 4G CAT1 IoT Communication Module brings reliable 4G connectivity to IoT projects in regions including Europe, the Middle East, Russia, Thailand, and Africa. Supporting LTE-FDD bands B1/B3/B7/B8/B20/B28, this module provides up to 10Mbps downlink and 5Mbps uplink speeds, making it an ideal choice for applications requiring remote monitoring, control, and data exchange. It incorporates multiple network protocols—such as TCP, UDP, HTTP, and MQTT—simplifying complex communication setups into a straightforward UART interface with AT command support, thereby speeding up development while minimizing programming demands.

Efficient power management features include a low sleep mode current of 0.6mA, making it perfect for battery-sensitive applications. When reporting data at 5-minute intervals, a 500mA battery can sustain the module for up to 36 days, offering long-lasting operation for IoT deployments. A built-in USB network card (Type-C interface) enables plug-and-play compatibility with PCs, Raspberry Pi, and other development boards without requiring drivers, adding flexibility and ease of use. The module is ideal for a range of IoT applications, including agriculture, environmental monitoring, remote control, and smart home systems.
