Features of the Seeed Studio XIAO ESP32S3 Development Board

The Seeed Studio XIAO Series are tiny development boards with a thumb-sized size and a comparable hardware architecture. The Seeed Studio XIAO ESP32S3 uses a 240MHz Xtensa 32-bit LX7 dual-core processor, allowing WiFi and Bluetooth 5.0 wireless connectivities, deep sleep mode with power consumption as low as 14 μA, and lithium battery charging management. It serves as the ideal option for robotics, smart homes, wireless wearable technology, and the Internet of Things. The 32-bit RISC-V-based XIAO ESP32C3 was introduced last year.

The XIAO ESP32S3 is designed to easily handle a variety of challenging multitasking assignments thanks to its powerful Xtensa 32-bit LX7 dual-core processor, 8MB PSRAM, and 8MB Flash memory.


  • Powerful MCU Board: Include the ESP32S3 32-bit, dual-core, Xtensa CPU, mounted multiple development ports, and it also supported by Arduino/MicroPython
  • Outstanding RF performance: Supports 2.4GHz WiFi and BLE 5.0 dual wireless communication, and when linked to a U.FL antenna, supports remote communication of up to 100 meters.
  • Extensive Power Design: Lithium batteries have the ability to manage their charge, and four power consumption models are available. These models enable deep sleep mode, which has a power consumption as low as 14 μA.
  • Thumb-sized Compact Design: 21 x 17.5mm, adopting the traditional XIAO form factor, appropriate for applications with limited space, such as wearable devices.
