Product Description
The DFRobot Gravity: CAT1 A7670G Global 4G IoT Communication Module is a cellular modem module for wireless data communication over 4G CAT1 networks. The module is based on the A7670G and supports a manufacturer-specified maximum downlink rate of 10 Mbps and uplink rate of 5 Mbps. With support for LTE-FDD, LTE-TDD, and GSM, it is intended for deployment across global regions and a wide range of operator networks.
For integration into embedded and single-board computer applications, the module provides both UART and USB interfaces. UART enables connection to microcontrollers, while USB allows operation as a 4G network card on compatible systems such as LattePanda and other computing platforms. Network functions including TCP/IP, IPv4, Multi-PDP, FTP, FTPS, HTTP, HTTPS, and DNS are accessible through AT commands. The module also integrates microphone and audio power amplifier circuitry, enabling not only data transmission but also voice calling and SMS functions.
