## Overview

<table>
<tr><td>

The ESP32-S31-Korvo-1 V1.1 is a multimedia development board based on the ESP32-S31 chip. It features a dual-microphone array and supports speech recognition as well as near- and far-field wake-up. The board also integrates peripherals such as LCD, camera, and microSD, and supports JPEG-based video streaming for low-cost, low-power, connected audio/video and graphical UI product development.

> [!WARNING]
> The MCLK pin on ESP32-S31 is unconnected. Recommended sampling rate is 16kHz for audio!
