https://devzone.nordicsemi.com/f/nordic-q-a/5622/digital-mems-microphone-interface-with-nrf51822I&#39;m looking to integrate a digital (PDM/I2S) MEMS microphone into my nRF51822-based design. I&#39;d like some pointers to reference designs or other information -- the ones that seem relevant on the Nordic site (nRF6929) are locked :( Has anyone had successen-USTelligent Community 13Mon, 23 Feb 2015 12:57:35 GMThttps://devzone.nordicsemi.com/thread/19693?ContentTypeID=1Mon, 23 Feb 2015 12:57:35 GMT137ad170-7792-4731-bb38-c0d22fbe4515:afc6661e-ebe8-4dd2-9fc0-f625084ccf90Asbj&#248;rn<p>Not the technical answer you are looking for, but the reference design is something that requires a product key as it&#39;s something we want to keep a little closer to our chests. If you could send me a PM with where you are located I could put you in contact with our local sales force where you are to assist you on that matter.</p><div style="clear:both;"></div>
