Respeaker 2 mic need ports on 40 pin header used

can someone tell me all the ports on the 40 pin header that the product uses?

Was looking for exactly the same information and ran across the following: 2-mic and 4-mic linear array GPIO pins. I also added some information which may or may not be of use to you. Good luck with your project! :slight_smile:

Thank you very much :slight_smile:
