Product description: 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.

Main features of FireBeetle 2 Board

  • The ESP32-S3-U microcontroller - equipped with a fast Xtensa processor and up to 16 MB Flash memory, is an ideal base for many projects.
  • OV2640 camera - a camera connected to the CSI connector with a resolution of 2 Mpx and a viewing angle of 68°, is a great system for beginners in the field of image recognition.
  • Wireless communication - a built-in module equipped with 2.4 GHz WiFi and Bluetooth 5, with an external antenna, allows easy communication with other devices.
  • The battery charging module - ETA6003 - is designed for use with Li-Ion batteries and allows charging from a USB port with a maximum current of 1 A.
  • Many popular interfaces - including I2C, SPI, UART, PWM, ADC, GPIO - facilitate integration with sensors, actuators and other microcontrollers.
  • A dedicated power supply system - AXP313A - ensures proper power supply to the processor and camera, while limiting image interference.
