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

The FireBeetle 2 Board ESP32-S3-U (N16R8) module is a board based on the popular ESP32 microcontroller, capable of communicating via WiFi and Bluetooth . The wireless interface antenna is located on an external module connected to the SMA socket. The clock speed of both processor cores is up to 240 MHz, and the user has 8 MB PSRAM and 16 MB Flash memory at their disposal. The board also has GDI connectors for connecting a display and a CAM to which the OV2640 camera is connected. Power can be supplied via the USB Type-C connector, which, thanks to the ETA6003 chip, also allows you to charge lithium-ion batteries. Thanks to separate systems powering the processor and the camera, image interference can be minimized.
