[Seeking Help] Looking for the Schematic Diagram of the Microphone Array

  • Hi guys, I' m a college student and am working on my project using ultrasonic beacons to navagate robots.
    This project requires a microphone array similar to the one provided by the KENDRYTE.
    However, in my case it is required to use band-pass filters to distinguish soundwaves of two different frequencies generated by two separate beacons. So I need to construct the microphone array myself.
    It would be great help to refer to the schematic diagram of the array but it cannot be directly derived. After contacting a personel of KENDRYTE, he/she instructed me to post here for help. So here I am.
    Any related help will be considered valuable. Thank you all.
