Gravity: High-Speed CAT4 SIM7600G-H Global 4G Communication and GNSS Positioning Module (150Mbps/50Mbps)

The Gravity SIM7600G-H is a high-speed 4G CAT4 communication and GNSS positioning module delivering downlink speeds up to 150Mbps and uplink speeds up to 50Mbps. Designed for global cellular networks, it suits students, hobbyists, and engineers building mobile IoT nodes, logistics trackers, and remote monitoring systems.

Global multi-band coverage and GNSS

The module supports worldwide LTE-FDD, LTE-TDD, WCDMA, and GSM frequency bands alongside GPS, GLONASS, and BD satellite navigation. An integrated microphone and audio amplifier circuit also enable voice calling and SMS functionality across MT, MO, CB, Text, and PDU modes.

LattePanda USB network card integration

The module connects to single-board computers such as the LattePanda 3 Delta via USB to function as a dedicated 4G network card. Driver support is available across mainstream operating systems including Windows, Linux, and Android.

Raspberry Pi cellular expansion

Easily pair the SIM7600G-H with single-board computers like the Raspberry Pi 5 to provide broadband internet access in off-grid deployments. This makes it straightforward to handle high-bandwidth data transfers, SMS messaging, and telemetry.

Comprehensive hardware and protocol architecture

Controlled via standard AT commands, the module integrates network protocols including TCP/IP, IPV4, Multi-PDP, FTP, FTPS, HTTP, HTTPS, and DNS. Onboard hardware includes IPEX antenna connectors for cellular and GNSS, status indicator LEDs, and a push-lock SIM card slot.

Arduino microcontroller interfacing

Featuring a standard Gravity PH2.0-4P UART interface with 3.3V to 5V logic compatibility, the board connects seamlessly to microcontrollers like the Arduino UNO. Embedded projects can easily send sensor data, receive SMS alerts, and read satellite coordinates.
