Gravity: CAT1 A7670G Global 4G IoT Communication Module (Compatible with Arduino / LattePanda)

The Gravity CAT1 A7670G 4G Communication Module provides reliable global cellular connectivity with data rates up to 10Mbps downlink and 5Mbps uplink. Compatible with both Arduino microcontrollers and LattePanda single-board computers, it is ideal for makers, students, and engineers developing remote IoT projects. It supports high-speed data transmission, voice calls, and SMS messaging across international networks.

LattePanda and SBC network integration

The module functions as a 4G USB network card for single-board computers such as the LattePanda 3 Delta, offering driver support across Windows, Linux, and Android. It provides reliable broadband connectivity for remote compute tasks without requiring extra networking shields.

Onboard audio and hardware interfaces

Equipped with an onboard microphone, audio power amplifier circuit, and dedicated speaker output, the module supports two-way voice calls alongside data transmission. It also includes a push-lock SIM slot, IPEX antenna connector, and status LEDs for power and network monitoring.

Simple Arduino UART connectivity

Using the standard Gravity PH2.0-4P interface, the module connects directly to Arduino Uno and other 3.3V or 5V development boards via UART. Control is managed through standard AT commands, allowing developers to exchange data without low-level protocol programming.

Global multi-band cellular support

The integrated A7670G chipset operates across a broad range of LTE-TDD, LTE-FDD, and quad-band GSM frequencies. This comprehensive band coverage ensures network compatibility across local and global mobile operators for mobile tracking and logistics.

Embedded IoT communication protocols

Built-in hardware protocol stacks support TCP/IP, IPv4, Multi-PDP, FTP, FTPS, HTTP, HTTPS, and DNS for direct cloud communication. The module also features comprehensive SMS capabilities, supporting Text, PDU, MT, MO, and CB modes.
