SIMA7670C 4G/LTE GSM Board (LM39302) V1.1

The SIM A7670xx 4G LTE Board is a Cat-1 Module which supports wireless communication modes of LTE-TDD/LTE-FDD. It supports maximum 10Mbps downlink rate and 5Mbps uplink rate. This board features a serial interface and is based on the SIMCOM A7670xx LTE modem. The serial interface allows for simple communication with a computer or laptop via a USB to Serial adapter or TTL converter. AT instructions are used to communicate with the A7670xx.

This ADIY SIM A7670xx 4G LTE Board has onboard UART Logic Level Conversion, and Vdd needs to be connected to host reference voltage. It has a UFL connector, which allows connection of any antenna with this board. Apart from this, the module is very compact in size. It can be easily embedded in any customized PCB and it can also be mounted using screws.

This module has sleep mode power consumption of <10mA, allowing the board to be powered by a small Li-ion Battery. LM39302R is used to step down the input voltage, which effectively allows input voltage as low as 9V.

The SIM A7670xx 4G LTE Board supports multiple built-in network protocols like HTTP, HTTPS, FTP, FTPS etc., supports drivers for main operation systems (USB driver for Windows, Linux and Android etc.) and software function, AT commands are compatible withSIM7500/SIM7600 series modules.
