Additional Microphones for ReSpeaker Core v2

Post by miguel.karpf » Thu Sep 27, 2018 10:38 pm

Hello,

for my project I need to expand the ReSpeaker Core v2 by at least two additional SMD microphones, around 2m away.
Since I want as few additional components as possible I think I2S or I2C is the way to go.
I do not need all of the microphones at the same time. (Either my added ones or the original installed)

As far as I see the I2S are not accessible from external.

Is there a way to achieve this?

Thanks,

Miguel
