Networked microphone for voice assistant

Is there a premade networked microphone that I can use for the voice assistant? I was going to get a few and put them around for coverage. My odroid is to far away to be useful at all with a USB microphone.

Not sure about pre-made options but fitting a microphone to an ESP32 is super easy. There’s a full tutorial on Github.

You can just use the microphone without the LED’s and speaker if you don’t want those.
