ESP32-A1S Audio Kit Media Player

Hi Omri,
I’ve started working with the A1S but it’s a bit of a nightmare for lack of documentation.
Could you share some code so I can figure out how to access the LED’s, switches and audio parts? Anything could help a lot.
Best regards

I just got my board and thank you so much for the Yaml code, providing all the details. This helped me A LOT setting things up.

Since there are microphones on the board, I was wondering if you can do a wake word detection on the device and then use HA as a server to receive the audio streams, decode them and send back the reply? Anyone tried this already?

Has anyone tried Resonate with this yet?

if anyone is interested how it can work with the new dac_audio stack
here is my working config
