RPI Audio Amplifier 2x80W Peak Output Class D HiFi AMP Pro Hat Featuring 192KHz/24bit MA12070P Support Volumio, MoOde, Raspbian,and LibreELEC for Raspberry Pi 5 4 3 B+ Pi Zero

Worked for 4 days. Stopped outputting sound. Checked my project logs and ALSA can no longer communicate with the device. Tried everything. The other 1-star reviews were right

This amplifier sounds great, very clear. It's not super powerful but plenty for some small bluetooth/network bookshelf speakers or a soundbar type application. I ran this on a Rpi Zero w 2 using Volumio, and pumped music through it for several days in a row and the IC never even got warm. The supporting documentation from github was pretty good as well. As a seasoned EE, i can tell the make puts a lot of attention into their layout and it looks professional. Overall I'm very happy with the purchase and it will allow me to do the testing I need.

As others have reported, this device stopped working after a few months.

Attached this hat to my pi4 and fresh installed a new raspbian OS with no audio cables attached. Left the pi to do it's update for 5 min or so and hear fizzling & crackling. I come back to the capacitor leaking fluid and immediately shut off power.This pi was only powered by the pi itself and not with any other connection to other power, speakers, or DC jack. Will return and buy something else for an audio hat.

Tested this board with Raspberry Pi Zero W with Moode installed.Using this board to drive a couple outdoor speakers. It works well so far, not sure if it really has a 80w x 80w peak capacity but I don't really have a need to test it.All I know it is able to get the speakers as loud as I need them and the sound quality is great to my ears. 5 stars is also for the fact that this seems to be a nicely designed product at a decent price - screw terminals are pretty good (lots of cheap products will use the inferior spring kind that really suck), and the board provides 5V power to the Raspberry Pi off of its own supply.

I got this today and attached to my Pi following the instructions per the QR link to the manufacturer’s Git Hub site. I followed the instructions implicitly. Taking note that the main chip was subject to damage if the dc port was powered when plugging in the supply. My power supply was powered off and I then connected the dc jack to the amp and then powered up the power supply to power the device. It immediately smoked the processor. I used a 18V supply so as not to be near the maximum limit. Not very impressive. I am returning it tomorrow. If you closely read the manufacturer’s GitHub they admit that the device is very delicate and easily damaged and are working on a fix.

Was using this off and on for a media center project i was doing with one of my old 3Bs unfortunately after about 3 months of use the amp is no longer working. Was working well prior for roughly an hour of playback at a time but now its just dead and looking for an alternative plug and play type of product.

So far so good. Hopefully there won’t be any quality issues like others have experienced. A couple of notes— the GitHub manual has the speaker negative terminals wrong. They should be the inside two.The other thing to note is that the DAC needs to be set to the MERUS Amp hat. I’ve attached the picture below from Moode.I had to add the following lines to the /boot/firmware/config.txt file.dtoverlay=merus-ampdtoverlay=force_eeprom_read=1
