ESP32S3 4G LTE CAT1 SIM7670G
It is becoming increasingly clear that the 2G GSM/GPRS is on the verge of, or has already reached, the end of its lifespan in many countries and regions, including Australia and Canada. However, there are still some projects that require remote wireless communication or access to the Internet, such as remote environmental monitoring. Given the investment required and the inherent risks, the LTE 4G is currently the most viable solution for many cases，until we finally find a better way such as 5G/ Starlink in the distant future.
We have already implemented the Maduino Zero 4G LTE module, which is based on SIMCOM7600(CAT4). Our new ESP32S3 4G LTE(SIM7670G) module offers additional features:
1. Lower Price: This module is based on the SIM7670G 4G module, CAT1, which offers a more affordable price point. The CAT1 is well-suited for IoT applications such as remote sensor monitoring.
2. With ESP32S3 controller, it features WiFi/Bluetooth, which can be used for local application setting (with phone), making it ideal for applications such as shared bike.
This ESP32S3 4G LTE module utilizes the SIM7670G CAT1 module to assist makers in establishing seamless WiFi/Bluetooth/4G connections. Additionally, this module provides comprehensive 4G access to your computer/PI, as well as telephone/SMS functionality.
ESP32S3 4G LTE SIM7670G module Details
1.As IoT applications 4G access to the Internet:
For IoT applications, that run based on MCU such as Arduino/ STM32, the controller communicates with A7670 with AT commands, to create an Internet connection. This is mode fits most of the simple applications. Makerfabs ESP32S3 4G LTE module is based on controller ESP32S3, it communicate with A7670 with AT command, to add ESP32S3 the function of 4G LTE connection;
2. 4G access for CPU such as PC/Raspberry Pi...
For platforms with operating systems such as PC/ Raspberry Pi, with the right driver installed, ESP32S3 4G LTE module can be directly 4G node. Connect the SIM7670G USB to PC and install the driver, to add your PC 4G connection ability immediately;
There are 3 version of Makerfabs 4G LTE products, please select the right version depends on your usage location/4G LTE provider:
