Seeed Studio XIAO ESP32S3 Sense – 2.4GHz Wi-Fi, BLE 5.0, OV2640 camera sensor, digital microphone, battery charge supported, rich Interface, IoT, embedded ML

The Seeed Studio XIAO ESP32S3 Sense is centered around the highly integrated Xtensa processor ESP32-S3R8 SoC, offering support for 2.4GHz WiFi and low-power Bluetooth® BLE 5.0 dual-mode functionality, catering to a wide range of wireless applications. Additionally, it boasts lithium battery charge management capabilities.

Distinguished as the enhanced iteration of the Seeed Studio XIAO ESP32S3, this board is equipped with a plug-in OV2640 camera sensor capable of displaying images at a full resolution of 1600*1200 pixels. Moreover, its base is compatible with the OV5640 sensor, accommodating resolutions of up to 2592*1944 pixels. The inclusion of a digital microphone further enhances the board’s functionality, enabling voice sensing and audio recognition capabilities.

Featuring a robust system-on-chip (SoC) and integrated sensors, this development board incorporates 8MB of PSRAM and 8MB of FLASH on the chip, alongside an additional SD card slot supporting up to 32GB of FAT memory. These specifications not only provide ample programming space but also unlock a plethora of possibilities for embedded machine learning scenarios.

Note: Due to small size heating issue will be generated but will not affect the working of the product.
To avoid excessive heating, you can use external heatsink.
