I2S in ESP32-A1S module?

Postby allex1978 » Wed Aug 07, 2019 10:10 pm

Hi,
Does the ESP32-A1S modle have an external I2S bus pins? Can I somehow disable AC101 pins and use them as I2S, or SPI or etc. I want to use ESP-ADF with external DAC and MEMS microphones. Is it possible?

Hi
do you not have third party / reference from this modul?
