Software Installation
Note: This example assumes you are using the latest version of the Arduino IDE on your desktop. If this is your first time using Arduino, please review the following tutorials.
Arduino Board Definitions and Driver
We'll assume that you installed the necessary board files and drivers for your development board. In this case, we used the IoT RedBoard - ESP32 which uses the CH340 USB-to-serial converter. If you are using a Processor Board, make sure to check out its hookup guide for your Processor Board.

How to install CH340 drivers (if you need them) on Windows, Mac OS X, and Linux.
Installing the Arduino Library
We'll be using the WM8960 audio codec and connecting to the differential microphone input pins. The SparkFun Arduino library can be downloaded with the Arduino library manager by searching 'SparkFun Audio Codec Breakout WM8960' or you can grab the zip here from the GitHub repository to manually install.
