Gravity: Air780E 4G IoT CAT1 Communication Module For China, India, SEA (Raspberry Pi / LattePanda Compatible)

The Air780E is a state-of-the-art 4G CAT1 communication module designed to operate seamlessly within the LTE-FDD B1/B3/B5/B8 and LTE-TDD B34/B38/B39/B40/B41 frequency bands. With high-speed connectivity, streamlined network integration, and efficient power management, the Air780E is an ideal choice for IoT projects and development boards.

The Air780E communication module supports a maximum communication rate of up to 10Mbps (downlink) and up to 5Mbps (uplink). It comes integrated with a rich set of network protocols including TCP/UDP/PPP/HTTP/NITZ/NDIS/NTP/HTTPS/MQTT, and employs a standard serial port for data transmission and reception. This converts the previously complex communication methods into simple serial port programming, significantly reducing software development costs and facilitating rapid IoT project development.

Additionally, the module features a low power consumption mode of 0.6mA during sleep mode, UART serial port data wake-up, and periodic interrupt wake-up. If data is reported every 5 minutes, a 500mA battery can last up to 26 days in PRO mode and 36 days in STD mode, greatly benefiting IoT projects sensitive to power consumption.

The Air780E module includes a built-in USB network card function, using a TYPE-C interface for connection. Through practical testing, this series of modules supports driver-free USB network card functionality on PC, Raspberry Pi, UNIHIKER, and LattePanda, allowing for the rapid addition of 4G communication capabilities to your development boards. Additionally, the onboard UART communication interface and AT command usage facilitate easy connections to various MCU or development boards for swift development of projects based on 4G communication networks.
