Waveshare has launched two new ESP32-S3 modules: the ESP32-S3-SIM7670G-4G and the ESP32-S3-A7670E-4G. Both support 4G, GNSS, Wi-Fi, Bluetooth, and solar charging, and have a holder to put in an 18650 battery. The main difference is in their cell network support. The SIM7670G model works with a wide range of 4G networks while The A7670E model supports both 4G and 2G networks.

Previously, we’ve explored several LTE-based modules, including the SparkFun LTE Stick, Project Walter, and PicoCell 4G If you’re interested in this topic, feel free to check out those discussions for more insights.

The ESP32-S3-A7670E-4G board is powered by the ESP32-S3R2 chip with a dual-core processor at 240MHz, 512KB SRAM, 384KB ROM, 2MB PSRAM, and 16MB Flash, and supports 4G and 2G networking, along with GNSS positioning capabilities for GPS, BeiDou, and GLONASS, facilitated by a GNSS IPEX1 connector.

The board also includes an OV2640 camera (1600×1200 resolution, 15fps), microphone and speaker for calls, USB Type-C, MicroSD slot, RGB LED, and DIP switches for controlling the camera, USB, and 4G module.

The board has a built-in IC for charging lithium batteries, managing power, and measuring battery capacity. It also includes safety circuits and supports both USB and solar charging, with the ability to measure battery capacity in real-time.
