 Overview
 --------
 
-ESP32-DevKitC is a small-sized ESP32-based development board produced by `Espressif <https://espressif.com>`_. Most of the I/O pins are broken out to the pin headers on both sides for easy interfacing. Developers can connect these pins to peripherals as needed. Standard headers also make development easy and convenient when using a breadboard.
