    Works well
    Using to add microphone + headphones to Pi Zero. Works well. Couple annoyances... First, the HAT comes with a 2x20 header jack presoldered, so cannot be installed on bottom on Pi Zero, thus is not useable with Pi Zero official case. Second, the speaker connector is not common -- would be nice to see screw terminal blocks, into which any speaker wires can be inserted. Third, would love to see a .deb file which distributes drivers, rather than the install.sh script which takes ~10 minutes to compile + install.

    Perfect for a voice assistant !
    That card is just perfect to use on Raspberry PI 3+ ou 0 W fos building your own non intrusive voice assistant based on SNIPS !
    Have these cards on around 10 raspberry in my house setup with SNIPS and interacting with my Home assistant system and it works really great.
    Stable, good voice recognition without any complicated setup on card.
    Allows you easily to plug either wired speaker on jack or headset or external speaker.
    Perfect product for cheap, efficient and fully private voice assistant home made.

    I'm using this product to add microphones to Pi Zeros and Pis - quality is great for the price - highly recommended. I had one problem - a consistent pulsing noise: it turned out to be interference from the power supply/USB cable.
