Seeed Studio XIAO ESP32S3
Seeed Studio XIAO ESP32S3 is a compact, high-performance ESP32-S3 development board built for smart homes, IoT, wearables, and robotics. It features a dual-core Xtensa® LX7 processor up to 240 MHz, Wi-Fi 2.4 GHz, and Bluetooth 5.0 LE, combined with 8 MB Flash and 8 MB PSRAM for demanding applications.
Designed for both prototyping and production, it supports integrated battery charging, ultra-low-power operation (down to ~14 µA deep sleep), and flexible antenna options via an onboard PCB antenna and U.FL connector for extended range or enclosed installs. Programming is supported via Arduino and MicroPython, with fully open-source hardware resources.
