The A7670G-H 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-H 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 SIM series wireless communication modules offer multiple products to choose from. This series of 4G products is differentiated by communication rates and satellite positioning capabilities. Click here to check the selection guide of 4G communication modules.
