New Raspberry Pi 4-Microphone HAT

I just saw an article about a new 4-microphone array designed for Raspberry Pi. Looks like it will be a good fit for the AI components of HomeAssistant!

ReSpeaker

Any thoughts on this product?

I saw that as well - I thought it might be a good fit for a Google Home on a RPi… good price too!

Anyone get it working? I can’t see to get it to recognize or light up. Thought it would go well with the Snips integration

greetings HA’s geeks
first i want to say that am a total noob and i need enlightenment

lately I was researching on how to add microphones for google assistant so that i can cover all the house
i saw that the respeaker module( microphone module for raspberry) was a good choice

do i need the google assistant product so i could use the respeakers? or i can connect to the google server through the rspberry pi ?
can anyone direct me to a link or teach me on how to connect it ?

for example i need four or five of those microphones modules
i am guessing that the wiring process needs an some kind of amplifier so that it will avoid the voltage drop (the respeaker is mounted on the ceiling or on the wall and the raspberry pi is in another room on the server rack )

i really cant find a full guide for this topic ?
is it applicable to use 5 respeakers or normal usb microphones on one google assistant module ?
