Seeed Studio XIAO ESP32 S3 Sense with Camera

The Seeed Studio XIAO ESP32S3 Sense is a user-friendly development board based on the powerful ESP32-S3R8 SoC Xtensa processor. It offers support for fast 2.4GHz WiFi and energy-efficient Bluetooth BLE 5.0 in dual mode. The board is equipped with a high-resolution OV2640 camera sensor that delivers crisp images with a resolution of 1600x1200 pixels. In addition, it has a digital microphone for voice recognition applications. There is plenty of room for programming and data processing, thanks to 8MB PSRAM and 8MB FLASH directly on the chip and an additional SD card slot. This expands the possibilities for use in embedded machine learning scenarios. The XIAO ESP32S3 Sense maintains the characteristic compact design and the elegant single-sided assembly of the Seeed Studio XIOA series. It also has a practical lithium battery charge management function. With its versatility and extensive range of functions, the XIAO ESP32S3 Sense is perfect for projects that require a combination of wireless connectivity, image processing, voice recognition and support for embedded machine learning.
