### ESP32-A1S ### ESP32-A1S
Works with [ESP32-A1S](https://docs.ai-thinker.com/esp32-a1s) module that includes audio codec and headset output. You still need to use a demo board like [this](https://www.aliexpress.com/item/4000765857347.html?spm=2114.12010615.8148356.11.5d963cd0j669ns) or an external amplifier if you want direct speaker connection.
