KEYESTUDIO ReSpeaker 2-Mic Pi HAT V1.0 for Raspberry Pi 4/4B, Raspberry Pi 3 3B+/2 2B

First I thought the 3.5mm output wasn't working, but found that the volume is initially set to 0%. I'm running headless with Raspberry Pi OS 12 so I used command line wpctl status to identify the sink, then wpctl set-default and wpctl set-volume to raise the volume level. Hope this is helpful. Works great and the price is low so I ordered three of these hats. Excellent.

Not much to say here. Works as expected.

Works perfectly with excellent reception of voice commands for my home assistant.

Following the guide i got it working with home assistant and an openai/elevenlabs api integration allow ky smart home to truly be smart and unique

I bought this to attempt to create a locally functioning voice activated smart device using the Wyoming protocol with Home Assistant. It seems to be working. For the price, this hat is a good buy and functions as advertised on a raspberrypi zero 2w. Make sure you follow all the instructions for downloading and installing the drivers.

This has built in amp with speaker output (no speaker provided). The mic works great. I use it with SNIPS and get plenty of sound with a $6 speaker. The GROVE connectors are a definite plus. I use the I2c to control a servo board.

Bought this card based on the reviews and tried to make it work with Raspberry Pi Zero. Followed the documentation on Seedstudio diligently for this product for Raspberry Pi. It just does not work as documented. Every step is a hurdle. Takes lots of research and workarounds. Starting to feel it's just a waste of time trying to make it work. Either the library is outdated and has not kept up with later versions of OS or just bad documentation. Either way, not a pleasant experience. Will try for another couple of days and if it does not work, will return. Definitely DO NOT RECOMMEND.

I got mine working but only after a lot of adjustments. They include instructions on installing the drivers, but the instructions only work if you are using specific kernels. I set up a cross compiler and was able to get the drivers installed using a hand-rolled kernel. I also ran into an issue that their suggestion for modifying the boot file didn't work if either of the lines being added already existed in the boot file but were commented out. (luckily I checked the file and saw one of the lines it was trying to add was already there and thus the script didn't try to add it -- but it was commented out so it wouldn't have worked)After setting up the self-compiled kernel and getting the drivers compiled and the boot files modified, it recognized the shield and the module loaded fine and works like a champ. Then I went to plug in a grove device.The so-called 'grove' connectors aren't. They are bigger, wider and the pins inside are wider spacing and bigger diameter. I had some pcb grove connectors on hand already so I pulled the pins out of the plastic housing, pulled the plastic part of the board's 'so-called grove' connectors off and used long nose pliers to carefully decrease the spacing in the existing pins then force shoved them through the holes on the back of an actual grove connector which seems to work with a little extra 'push' on the grove device's connector to get it onto the larger diameter pins.
