Overview
The LILYGO T-SIM7080G S3 is a powerful IoT development board combining the ESP32-S3 dual-core processor with the SIMCom SIM7080G multi-band NB-IoT/LTE-M module, enabling global cellular connectivity for low-power IoT deployments. The board features 16MB of flash memory and 8MB of PSRAM, providing ample resources for complex embedded applications.
The SIM7080G module supports NB-IoT and LTE-M (Cat-M1) networks across multiple frequency bands, making it suitable for worldwide deployment in smart city, asset tracking, and industrial monitoring applications. An integrated GNSS receiver provides location services without needing a separate GPS module.
Designed with power efficiency in mind, the T-SIM7080G S3 supports 18650 lithium battery operation with onboard charging circuitry. The ESP32-S3's ultra-low-power modes combined with NB-IoT's inherently low power consumption make this board ideal for battery-operated remote sensors that need to send periodic data updates over cellular networks.
The board exposes sufficient GPIO pins for connecting external sensors and peripherals, while the USB-C port supports both programming and charging. Compatible with Arduino IDE, ESP-IDF, and MicroPython development environments.
