M5Stack COM.LTE Data Module (A7600C CAT1 4G LTE)

Description

The M5Stack COM.LTE-DATA module is a compact, stackable cellular communication solution designed for low-power IoT applications. It integrates the A7600C LTE CAT1 modem, delivering stable data transmission across LTE, 3G, and 2G networks with support for essential TCP/IP protocols, including IPv4/IPv6, FTP/FTPS, HTTP/HTTPS, and DNS. Its architecture prioritizes energy efficiency, making it ideal for battery-powered remote sensing and telemetry systems.

The module features a dedicated external power supply input (5V-12V DC) and a user-configurable DIP switch for mapping its UART interface to non-conflicting GPIO pins on M5Stack host controllers. This design ensures reliable serial communication at 115200bps for AT command control while maintaining compatibility with the M5Stack ecosystem. The inclusion of an SMA antenna connector and dual status LEDs provides robust RF performance and immediate operational feedback for field deployments.
