ES8311

The es8311 platform allows your ESPHome devices to use the ES8311 low power mono audio codec. This allows the playback of audio via the microcontroller from a range of sources via Speaker or Media Player.

The I²C bus is required in your configuration as this is used to communicate with the ES8311.

  - platform: es8311

Configuration variables

Section titled “Configuration variables”
  • bits_per_sample (Optional, enum): The bit depth of the audio samples. One of 16bit, 24bit, or 32bit. Defaults to 16bit.
  • sample_rate (Optional, positive integer): I2S sample rate. Defaults to 16000.
  • use_mclk (Optional, bool): Use the MCLK signal to control the clock. Defaults to True.
  • use_microphone (Optional, bool): Configure the codec’s ADC to use PDM microphone input instead of analog. Defaults to False.
  • mic_gain (Optional, enum): The gain applied to the ADC microphones. One of 0DB, 6DB, 12DB, 18DB, 24DB, 30DB, 36DB, 42DB. Defaults to 42DB.
  • address (Optional, int): The I²C address of the driver. Defaults to 0x18.
  • i2c_id (Optional): The ID of the I²C bus the ES8311 is connected to.
  • All other options from Audio DAC.
