  • ESP32-audioI2S

    Play mp3 files from SD via I2S

  • ULPSoundESP32

    If you got TF card reader, you could use https://github.com/elshnkhll/ULPSoundESP32/blob/master/SD/sd.ino . I made it to work with LILYGO® TTGO T5 V2.2 ESP32 2.9" EPaper Plus. Borrowed from https://github.com/bitluni/ULPSoundESP32 which uses ULP to free up main processor and has version without a card reader, using just a plane sound data file.
