FireBeetle 2 ESP32-S3-U - WiFi, Bluetooth - OV2640 Camera - DFRobot DFR0975

The FireBeetle 2 Board ESP32-S3-U (N16R8) module is a board based on the popular ESP32 microcontroller. This system has the ability to communicate wirelessly, via WiFi and Bluetooth . The clock speed of both processor cores is up to 240 MHz. The user can use up to 8 MB of PSRAM and 16 MB of Flash memory. The module also has space for GDI and CAM connectors, to which the OV2640 camera is connected. Power can be supplied via the USB Type-C connector or a dedicated pin. The dedicated ETA6003 system also allows you to charge lithium-ion batteries. Thanks to separate systems powering the processor and the camera, image interference can be minimized.
