XIAO ESP32S3 unsoldered

The Seeed Studio XIAO ESP32S3 is a thumb-sized development board built around the ESP32-S3 dual-core processor, with 2.4 GHz Wi-Fi and Bluetooth 5 LE. It packs 8 MB PSRAM and 8 MB flash into a 21 × 17.8 mm board, making it a strong choice for wearables, IoT sensors and small AI projects. This version is supplied unsoldered, so you can fit headers or solder it straight onto your own PCB.
