dears, I want to use Nano ESP32 to drive a I2S audio device, but I can find lots of instructions of Espressif ESP32. In the document of Nano ESP32 I cannot find a clear description whether it has I2S inteface or not.
The bad case is to buy a Espressif ESP32, but I would hope, Nano also has. Could anyone confirm? thanks.
In the end, if Nano also has I2S, which pins to connect?
Yes it has two I2S interfaces.
See this page:-
https://docs.arduino.cc/hardware/nano-esp32/
Click on the EPS documentation link. Then download the data sheet.
Then search the data sheet for "I2S".
It is a bit tricky to get at because it is part of the ESP32 matrix.
From the datasheet:
There are no specific pins assigned for I2S, this can be used by any free GPIO
See the datasheet chapter 8.2
thank you Mike, topic solved and closed.
thank you b707.
