Microphone options for nRF9061 DK

[nrao32]

Is there any analog to digital input on the nRF9061 SiP / DK? I essentially need to plug in a microphone to this, so I looked at a couple of options -- ADC, the DMIC interface through Zephyr (which I have yet to learn how to use), or one of the fancier ones using I2S (which I know nothing about, nor whether the nRF9061 supports it). I come from the cloud / software side of the world, so I'm learning as I go for a passion project of mine. Anyone have any recommendations for which microphone I could buy for the easiest integration and how to plug it in pin-wise to the nRF9061 DK? I was looking at the sample code in Bus Fault in DMIC Driver on NRF9160 After Upgrading to SDK Version 2.5.0 - Nordic Q&A - Nordic DevZone - Nordic DevZone as an option if I can find a compatible PDM mic, or maybe a simpler analog mic. Basically, I am a complete noob and looking for guidance as to how to plug a mic into this.

Hi.

Is there any analog to digital input on the nRF9061 SiP / DK?

Yes, there are inputs to the SAADC. You'll find the AIN0-AIN7 inputs together with GPIOs P0.13-P0.20, the ones marked with the function "Analog input" in the nRF9161's pin assignments list.

or one of the fancier ones using I2S (which I know nothing about, nor whether the nRF9061 supports it).

There is I2S support on the nRF9161. There is PDM support as well.

Anyone have any recommendations for which microphone I could buy for the easiest integration and how to plug it in pin-wise to the nRF9061 DK?

I don't have a specific microphone to recommend you but in general, a PDM microphone should be the easiest to set up.

Best regards,
