Stethoscope using nrf5340-audio

[Vivek]

We are developing digital stethoscope and would like to use nrf5340-audio DK as starting point. We need to first get the microphone out on the headphones jack in the DK and also to transfer the microphone voice data over bluetooth to our BLE headphones (5.3).

Is there any application reference or guidance on this so that we move on to our custom board as fast as possible?

Regards

Hi,

All our kits have all the schematics and hardware files available for reference if that is what you are looking for. 

We also have just the recommended ref design from the product specification\Datasheet
