M5 Stack SPK-Kit with I2S Microphone?

sparkydave · November 23, 2023, 2:18am

I have a couple of M5 Stack SPK-Kit’s which I’d like to try connecting I2S microphones to so I can use them as Voice Assistants. According to their website it should be possible.

Has anyone done this before?

Not sure if this helps you as you probably know or have already seen it already… but for what it is worth

Thanks Blacky, I’ll have a look into it. I guess where I was confused is that with the SPK-Kit, the GPIO of the Atom Lite are almost all directly plugged into the speaker control unit. Hopefully I can work something out based on this however.
