LilyGo T-SIM7000G 16MB SIM Development Board ESP32

This development board combines the powerful ESP32 microcontroller with the SIM7000G module for LTE-Cat-M1, NB-IoT, and GSM communication, making it suitable for energy-efficient, standalone IoT projects. Thanks to the dual-core processor and 8 MB PSRAM, the board provides ample computing power for demanding tasks, while 2.4 GHz Wi-Fi and Bluetooth 4.2 enable local wireless connectivity. The power supply is optionally through a USB-C port, a 18650 Li-Ion battery, or a 2-pin solar charging socket, with integrated charging and protection circuits safely recharging the battery.
