https://devzone.nordicsemi.com/f/nordic-q-a/21313/how-can-i-sample-audio-and-send-data-via-ble-on-nrf52Hi, my setup is: nRF52 DK PCA1040 v1.0.1; Adafruit MAX9814 electret microphone amplifier; My project concerns about: Sampling audio from the board with SAADC. A starting point could be, for example, 1s audio record every 15 secondsen-USTelligent Community 13Wed, 12 Apr 2017 11:50:11 GMThttps://devzone.nordicsemi.com/thread/83498?ContentTypeID=1Wed, 12 Apr 2017 11:50:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d9eac51f-ec02-43ef-8c16-6278cb3397b8endnode<p>Right, power consumption can be bigger. It seems to have easier integration (at least I2S worked in nRF5 SDK for me) but if power consumption in the main criteria then you are probably going right way. Good luck!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/83497?ContentTypeID=1Wed, 12 Apr 2017 10:21:17 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2d0362a2-e433-40af-b898-7a6bcb7a4f13stefano.luna<p>I prefer to stay with the SAADC beacuse i think it consumes less energy, as i could read here <a href="https://devzone.nordicsemi.com/question/112256/nrf52-microphone-saadc-pdm-or-i2s/.">devzone.nordicsemi.com/.../.</a></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/83496?ContentTypeID=1Wed, 12 Apr 2017 09:45:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c226c916-f3ac-44f2-bca7-db20a3e13e3bendnode<p>Slightly off-topic question: why to bother with such mic and ADC when nRF52 has I2S and PDM? Wouldn&#39;t be easier to use microphone compatible with these?</p><div style="clear:both;"></div>
