Waveshare ESP32-S3 A7670E 4G Development Board, LTE Cat-1 / 2G / WiFi / Bluetooth / Telephone Call / SMS / GNSS Positioning Support, Suitable For 4G Portable WiFi, Onboard Camera / Speaker / Antenna

The ESP32-S3-A7670E-4G (the development board) is a multifunctional, high-performance microcontroller development board designed by Waveshare. It integrates an A7670E 4G communication module, a universal OV camera interface, a TF card slot, RGB lights, an 18650 battery slot, a battery voltage measurement IC, a solar charging interface, and other peripherals. It employs the ESP32-S3R2, a system-level chip (SoC) that integrates low-power Wi-Fi and BLE5.0. Additionally, it comes with an external 16MB Flash and 2MB PSRAM. The SoC incorporates a hardware encryption accelerator, RNG, HMAC, and digital signature modules, meeting the security requirements of the Internet of Things (IoT).

The A7670E 4G communication module provides mobile network capabilities, enabling functionalities like portable Wi-Fi and IoT data transmission when combined with the ESP32-S3R2. Its various low-power operating modes cater to power consumption demands in IoT, mobile devices, outdoor monitoring, smart home applications, and other scenarios.
