## Description

Meet EdgeS3\[D\], a compact modular and re-usable ESP32-S3 module that lets you pick the perfect radio setup for every build. Switch between the onboard high-gain antenna and an external 2.4GHz antenna over u.FL in firmware, then get back to prototyping.

Ideal for battery-powered IoT nodes and dense embedded designs, EdgeS3\[D\] blends dual-core processing, ultra low deep sleep current, and an M.2 B-Key edge connector to drop straight into carrier boards with clean, reliable I/O.
