I have researched this a lot, but haven't found anything on which I can trust.
I want to use a particular ESP board to play audio. To play audio, I2S support is required. But, I know that not every ESP board break out the I2S pins from the chip. According to me, buying an ESP32 only to use the I2S would be a waste of money. So, my question is, if I just want to use I2S, which board is would be suitable? Please provide some references if you can.

Few months ago I tested successfully I2S with this library, I used the default pins:

bck_io_num = 26  
ws_io_num = 25  
data_out_num = 22  

which are available on many boards such as Lolin D32.

  • Can we use any pin for the I2S? – Puspam Mar 11 at 20:17
  • I don't think so, those pins should be internally wired to the I2S peripheral (but I'm not sure) – fabiuz7 Mar 11 at 20:28
  • You have to use the dedicated I2S pins. – Majenko Mar 12 at 1:21
