Overview
The LILYGO T-SIM7670G S3 is an advanced cellular IoT development board built around the ESP32-S3-WROOM-1 module featuring 16 MB flash and 8 MB OPI PSRAM. It pairs with the SIM7670G LTE Cat-1 modem to deliver reliable cellular connectivity with integrated GPS/GNSS positioning. The board includes a MicroSD card slot, solar charging input (5–6V), USB-C programming port (500 mA max charge), onboard battery management, and a dedicated board LED. The ESP32-S3 provides USB CDC on boot capability, eliminating the need for a separate USB bridge chip. All standard interfaces—I2C, SPI, UART, and SDIO—are accessible through the GPIO headers for peripheral expansion.
