Feb 9, 2023 — by Giorgio Mendoza 730 views

LILYGO has introduced a compact embedded board based on the ESP32-S3 SoC with Wi-Fi/BL5.0 and the SIM7080G module for CAT-M and NB-IoT connectivity. The T-SIM7080G offers flexible peripherals such as an SD card slot, a SIM card slot, camera support, an 18650 battery holder and a connector for solar input.

The T-SIM7080G features the ESP32-S3 module just as their T-TWR Walkie Talkie module launched last month.

    We from QuickSpot know the LILYGO products. They are complete with a charger but quite large and lack certification and longevity. Therefore we are building Walter: https://linuxgizmos.com/open-source-esp32-module-supports-5g-and-gps-connectivity/
