Connecting an external microphone

Post by benisjammin » Tue Jan 24, 2017 2:30 am


I bought a board without a microphone as I have a microphone designed specifically for my project. I would like to connect this microphone to the Audio Injector. It requires a bias voltage between 2 and 3.6 V. Is it possible to connect this to the microphone to the board? I can see from the CODEC data sheet that it should be possible but it isn't immediately obvious how to connect the microphone to the board.

Many thanks in advance
