Development board with the ESP-WROOM-02 WiFi module

Description

Development board with WiFi ESP-WROOM-02 module. The board has a USB-UART converter with the CP2102 system and a microUSB connector for communication with the ESP module. A Li-Ion battery placed on the bottom of the PCB was used for power supply. The battery is charged via a microUSB connector, and the charging process is controlled by a built-in circuit. On the edge of the board, the ESP module pins are also led out, which allows you to connect additional sensors. Thanks to its small dimensions, the set is perfect for applications in the field of IoT and mobile devices.
