FireBeetle 2 ESP32-S3 /  ESP32-S3-U is a high-performance main controller built around the ESP32-S3-WROOM-1-N16R8 /  ESP32-S3-WROOM-1U-N16R8 module. ESP32-S3-WROOM-1-N16R8 /  ESP32-S3-WROOM-1U-N16R8 comes with 16MB Flash and 8MB PSRAM for storing more data. The acceleration for neural network computing and signal processing workloads provided by the ESP32-S3 chip makes the module an ideal choice for a wide variety of applications, such as speech recognition, image recognition, and so on.

• FireBeetle 2 ESP32-S3 /  ESP32-S3-U offers an onboard camera interface for easy connection with a camera. Also, an independent camera power supply circuit is designed, which helps reduce interference from other signals to the camera. The board comes with an OV2640 camera that offers 2 megapixels, 68° FOV, and up to 1600*1200 resolution. Besides, its onboard, easy-to-connect GDI greatly saves the trouble of wiring for using with a screen. Meanwhile, the controller integrates a power management function, which allows users to charge a Li-ion battery and turn the hardware on/off.
  
• In addition, FireBeetle 2 ESP32-S3 /  ESP32-S3-U supports WiFi and Bluetooth 5 (LE) dual-mode communication, which reduces the difficulty of networking. Meanwhile, both Bluetooth Mesh protocol and Espressif WiFi Mesh are supported for more stable communication and a larger coverage area. With the support of Matter protocol, the microcontroller can be used to develop industrial standard smart home devices for a wider range of IoT and AIoT (Artificial Intelligence of Things)scenarios.
  

FireBeetle 2 ESP32-S3 / ESP32-S3-U can be programmed by Arduino IDE, ESP-IDF, and MicroPython. Both C and Python are supported.
