ESP32-WROVER is a powerful, generic WiFi-BT-BLE MCU module that targets a wide variety of applications, ranging from low-power sensor networks to the most demanding tasks. The board is also equipped with a GSM/GPRS module, SIM868, or Multi-Ban CAT-M and NB-IoT 4g Module, SIM7080G, for communication of data to cloud if WiFi is unavailable. Both of them also offer GNSS (GPS) functionality. This module is suitable both for IoT applications, due to its rich connectivity, and for industrial applications, as it can accept supply voltages in the range +9VDC ÷ + 24VDC. Inside the system, a LiPo 2000mAh backup battery allows the working of the module also in absence of a direct power supply.
