FireBeetle 2 ESP32-S3-U CAM AIoT microcontroller with camera

The FireBeetle 2 Board ESP32-S3-U from DFRobot carries the ESP32-S3-WROOM-1U-N16R8 module with two Xtensa LX7 cores up to 240 MHz, 16 MB flash and 8 MB PSRAM. Instead of an antenna on the board, the module has a connector for the supplied external antenna. A camera is included, according to DFRobot an OV2640 with 2 megapixels or an OV3660, it plugs into the camera connector with its own power supply. In addition there is a GDI connector for DFRobot displays, a charging circuit for a lithium battery, 2.4 GHz Wi-Fi and Bluetooth 5 (LE). It is programmed with Arduino IDE, ESP-IDF or MicroPython.

According to DFRobot, FireBeetle 2 and the first FireBeetle series are not compatible in pins and size, nor are the expansion boards.
