Overview
********

ESP32-S2-Saola is a small-sized ESP32-S2 based development board produced by Espressif.
Most of the I/O pins are broken out to the pin headers on both sides for easy interfacing.
Developers can either connect peripherals with jumper wires or mount ESP32-S2-Saola on a breadboard.
For more information, check `ESP32-S3-DevKitC`_.
