Review on 🔊 RASPIAUDIO Audio DAC HAT Sound Card (Audio Speaker MIC) for Raspberry Pi Zero/A+/B+: Pi 3/4 Model B - Superior Quality Compared to USB by Chris Morgan

Structure error noticed immediately after viewing. Its pins protrude from below directly opposite the metal cooler. It's a crazy design to short out your board. I had to send it back immediately. I'm still brave enough to try and use it by installing it very carefully, but the worst is yet to come. There is a button at the top to check if my Raspberry Pi malfunctions after pressing the button and eventually burns out :( I believe the pins actually touched the cooler when I pressed and that blew my Pi led to a short circuit, not to say the mic is of poor quality which I found on a one off test and it's not easy to find installation instructions, I just lost my Pi mind you!
