LilyGo T-SIM7080G-S3 with NB-IoT Cat-M and GPS

The LilyGo T-SIM7080G-S3 combines an ESP32-S3 (16 MB flash, 8 MB PSRAM, Wi-Fi and Bluetooth LE) with the SIMCom SIM7080G cellular modem for LTE-M (Cat-M) and NB-IoT and with GNSS positioning via GPS, GLONASS, BeiDou and Galileo. A power management chip charges an 18650 cell in the holder on the back, optionally also via a solar cell with 4.4 to 6 V. The 18650 cell is not included. Programming is done via USB-C, and a camera connector is available.

Switzerland: The SIM7080G modem only works with LTE-M (Cat-M) and NB-IoT, not with 2G, 3G or regular 4G LTE. Before use, check with the mobile provider whether the SIM card supports LTE-M or NB-IoT.

Important: Insert the SIM card before switching on. Cellular and GPS positioning do not work at the same time. The solar cell only charges the 18650 cell; without a cell it does not power the board.
