Seeed Studio XIAO ESP32-S3 - Soldered
Seeed Studio XIAO ESP32-S3 is a dual-core Wi-Fi and Bluetooth development board built around the ESP32-S3 chip, packed into the classic 21 x 17.8mm XIAO form factor. It runs a Xtensa LX7 dual-core 32-bit processor at up to 240 MHz and is supported by Arduino and MicroPython, giving it plenty of headroom for more demanding IoT and wireless projects.
Solder-Free for Instant Creation
This version comes with headers already soldered on, so there's no soldering iron required. Just unbox it and plug straight into a breadboard, ideal for rapid prototyping, workshops, and beginner-friendly builds.
Wi-Fi and Bluetooth with Long Range
The board includes a complete 2.4GHz Wi-Fi subsystem alongside Bluetooth Low Energy 5.0, and supports communication over 100m or more when connected to a U.FL antenna. Power management offers four modes, with deep sleep consumption as low as 14 μA, plus built-in lithium battery charge management for portable projects.
Thumb-Sized and Production-Ready
At 21 x 17.8mm, it keeps the classic XIAO footprint with single-sided component mounting, and its breadboard-friendly SMD design with no components on the back makes it easy to work with on the bench or integrate into a finished product.
