Hello, the nano comes with an i2s port, but does it comes with audio codec，thank you！
Jetson Nano provides I2S port to external Audio (optional). If customer needs audio I/O, a audio codec should be added to their design.
Well, the way I understand it is that the nano itself does not have audio encoding and decoding capabilities, which need to be implemented according to the capabilities of the project，ok?
