DFR AIR780EU 4G CAT1 IoT Communication Module LTE UART USB-C SMA

The DFR AIR780EU 4G CAT1 IoT Communication Module is a compact, high-performance cellular communication solution designed to add reliable 4G LTE connectivity to embedded systems and IoT devices. Based on the AIR780EU CAT1 platform, this versatile module supports LTE-FDD frequency bands B1, B3, B7, B8, B20, and B28, making it suitable for deployment across Europe, the Middle East, Africa, Russia, Thailand, and many other regions.

Designed to simplify IoT development, the module features a standard UART interface with AT command control, allowing developers to integrate cellular communication into virtually any microcontroller project without the complexity of implementing low-level networking protocols. It includes comprehensive support for TCP, UDP, PPP, HTTP, HTTPS, MQTT, NTP, NDIS, and NITZ, enabling rapid development of cloud-connected applications.

The AIR780EU supports download speeds of up to 10Mbps and upload speeds of up to 5Mbps, making it ideal for telemetry, industrial automation, smart agriculture, environmental monitoring, remote control systems, payment terminals, asset tracking, and smart building applications.

For maximum flexibility, the module includes both a USB Type-C interface and a Gravity UART connector. The USB interface functions as a driver-free 4G network adapter on supported platforms including PCs, Raspberry Pi, LattePanda, and UNIHIKER, allowing developers to quickly add LTE connectivity without additional drivers.

Power efficiency is another key advantage of the AIR780EU. Its ultra-low power sleep mode draws as little as 0.6mA, while UART wake-up and periodic interrupt wake-up functions significantly extend battery life in remote deployments. Combined with support for both 3.3V and 5V logic levels and a wide 5V-12V supply range, the module integrates easily into a wide variety of embedded systems.

Complete with a Nano SIM card slot, SMA antenna connector, and supplied LTE antenna, the DFR AIR780EU provides a professional, ready-to-deploy solution for engineers, makers, and industrial designers requiring dependable 4G IoT communications.
