@me-no-dev does this do PCM over i2s in stereo? Thanks

Hello.
Have the script on the ESP8266 on it and connected the VS1053.
Data stream is running, sound comes from the VS1053.
What must be the pinout between the ESP and the VS1053?
I connected so:

Thanks

preciso de ajuda, como enviar a musica que está tocando no meu smartphone para o esp? Por favor me ajudem.

Hello also possible the other way around send audio from Esp32 to PC??
