Seeed Studio XIAO ESP32S3

The Seeed Studio XIAO ESP32S3 is a powerful, compact development board built around the ESP32-S3R8 SoC, designed for edge AI, IoT, and wearable applications. Despite its thumb-sized form factor, it delivers high performance with rich wireless connectivity and extended memory, making it ideal for space-constrained, intelligent projects.

This version does not have the headers soldered on. If you prefer, we also stock a version that already has them soldered on already.
