Gravity: CAT1 A7670G Global 4G IoT Communication Module

The A7670G is an integrated wireless communication module featuring 4G CAT1 (with an uplinkspeed of 5Mbps and a downlink speed of 10Mbps). It extensively supports multiple bands,including LTE-FDD, LTE-TDD, and GSM, making it suitable for global regions and most operators’networks. The module is compatible with Raspberry Pi, Arduino, and LattePanda single-board computers, and can be used as a 4G network card.

The specific bands areas follows:

LTE-TDD: B38/B39/B40/B41

LTE-FDD: B1/B2/B3/B4/B5/B7/B8/B12/B13/B18/B19/B20/B25/B26/B28/B66

GSM: 850/900/1800/1900MHz

Additionally, the A7670G module integrates support for various network protocols includingTCP/IP, IPV4, Multi-PDP, FTP, FTPS, HTTP, HTTPS, DNS, and more. This allows for complex networkcommunications using AT commands without the need to learn or understand the underlyingnetwork protocols, offering strong compatibility and ease of use.

The A7670G communication module comes equipped with both UART and USB interfaces. It canconnect to other MCUs or main controllers via UART or to computers, Raspberry Pi, etc., as a USBnetwork card through the USB interface. It supports mainstream operating system drivers(Windows, Linux, Android, and other USB drivers).

Furthermore, the A7670G module includes a microphone and audio power amplifier circuit,enabling it not only to function for data transmission but also for making calls and sending textmessages.

The CAT1 SIM7600G 4G Communication Module can be connected to single-board computers like Raspberry Pi, LattePanda, etc., and can be used as a 4G network card for SBCs.
