Select the DAC codec connected to the board. Both options use I2S STD TX
|
|
to send PCM and I2C to configure the codec:
|
|
|
|
- ES8311: low-power mono ADC/DAC codec used on boards such as ESP-BOX
|
|
and ESP32-S3-Korvo-2.
|
|
- ES8389: stereo ADC/DAC codec used on boards such as ESP32-S31-Korvo-1.
