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

The A7670G is an integrated wireless communication module featuring 4G CAT1 (with an uplink speed 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 are as 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 including TCP/IP, IPV4, Multi-PDP, FTP, FTPS, HTTP, HTTPS, DNS, and more. This allows for complex network communications using AT commands without the need to learn or understand the underlying network protocols, offering strong compatibility and ease of use.

The A7670G communication module comes equipped with both UART and USB interfaces. It can connect to other MCUs or main controllers via UART or to computers, Raspberry Pi, etc., as a USB network 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 text messages.

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.
