    • 2 way audio using I2S

      I am working on a project where I am trying to do 2 way audio for a drone. I saw a forum post from a while back that suggested using a USB microphone for this application. Unfortunately the due to the small scale of the solution I am looking for (sub 30g for microphone and speaker) this is not a viable option. As such I am wanting to use MEMS devices and was hoping to use the I2S protocol that is mentioned briefly on the website in port J5. I am looking for some information on the viability of the solution as well as how many I2S hookups there are as ideally I would like to run a speaker and at least one microphone but ideally two. Additionally, my radio that is hooked into port J3 physically covers the J5 port so I am wondering if the I2S pins are exposed anywhere else on the board or if there are other hookup options available for I2S.
