## Using the AI Thinker ESP32 Audio Kit as SD Player
2+
3+
I found some cheap [AI Thinker ESP32 Audio Kit V2.2](https://docs.ai-thinker.com/en/esp32-audio-kit) on AliExpress and because I was tired of all the wires I had to connect to implement my different scenarios that are possible with my [Arduino Audio Tools Library](https://github.com/pschatzmann/arduino-audio-tools), I thought it to be a good idea to buy this board.

You dont need to bother about any wires because everything is on one nice board. Just just need to install the dependencies
8+
To access the files we use the SD library.
9+
10+
This example is using the indexed version which creates an index file on the sd.

### Note

The log level has been set to Info to help you to identify any problems. Please change it to AudioLogger::Warning to get the best sound quality!

8+
9+
In this example we use the SDMMC library which is provided by the ESP32. On the Audiokit all the pins must be on the on position!

This example is using the indexed version which creates an index file on the sd.
