XIAO ESP32S3 Sense

Hardware

This board is based on the ESP32-S3 with 8MB of flash, WiFi and BLE support. It has an USB-C port for programming and debugging, integrated battery charging and an U.FL external antenna connector. It is based on a standard XIAO 14 pin pinout.

ESP32-S3 is a low-power MCU-based system on a chip (SoC) with integrated 2.4 GHz Wi-Fi and Bluetooth® Low Energy (Bluetooth LE). It consists of high-performance dual-core microprocessor (Xtensa® 32-bit LX7), a low power coprocessor, a Wi-Fi baseband, a Bluetooth LE baseband, RF module, and numerous peripherals.

Additionally, Sense variant integrates a OV2640 camera sensor, microphone and sdcard slot.
