DROK 5W+5W Mini Audio Amplifier Board PAM8406 DC 5V Digital Stereo Power Amp 2.0 Dual Channel Class D Amplify Module for Speaker Sound System DIY

The quality of the solder mask is impressive. Music sounds decent, but of course two 5W speakers is not going to turn any heads. My application is just for a raspberry pi smart Google assistant. For spoken words, the speakers and amp sound terrific.

Very good product very good volume control

it worked great for what I needed. Plenty of volume and small size.

I bought the 5W+5W version of this amplifier for use with a 32" LCD TV and a pair of unpowered 8 ohm bookshelf speakers. It is being powered by the USB port on the TV. The input is connected to the TV's headphone output. The resulting sound is much better than the TV's internal speakers. I was surprised at how loud the speakers could get with this set up. Normal viewing is with the volume at about 1/4 but even at full volume the sound isn't significantly distorted. I took away one star because there is no EMI shielding. When the amp is close to the TV you can hear a little buzzing and hiss. You'll want to keep it away from EMI sources or use a shielded project box. I rated it "easy to install" because of the standard 3.5mm stereo connector and the screw terminals for the power and speakers. Check out the companies web site.

Neat little low-power amplifier works perfectly on my prototypes with cheap 4 Ohm speakers.

Was building an arcade and originally went with a wm8960 audio hat for the raspberry pi that was powering the arcade. Never could get the thing recognized across retropie or Batocera and gave up and found this. So easy to get sound were you want it and it blows the portable monitors speakers out of the water. No soldering necessary makes this little guy the real hero of my arcade. Will be using these again!

The input source has to be plugged in otherwise it is very difficult to attach it. For instance, I needed to connect an alarm speaker, which came with bare wires to an amplifier and there was no practical way of connecting this. On the other hand, if you need to connect something with 3.5mm jack it is perfect as in the video. Very good quality and does not need a heat sink because it does not get hot. Good sound quality for its size.

So I am basically using the 3.5mm audio jack for input but I wired directly to a PCM5102 also purchased from here. https://amzn.to/49uvKUO Now, I have to say it is working great as long as I do not touch the volume control. It is not totally bad but you can get quite a bit of hum at high volume by just touching the volume. It may get better once I put in a case it is open air right now so the 60 Hz is easy to pickup on low side audio. However, there is a thing that makes this worse. The RCA jacks, they appear to be wired backward. That is the gold outside part of the jack is actually connected to the Left and Right + inputs! OOPS, that is not good that is supposed to be the grounded part of the RCA with the tab on the inside of the hole the Pos Line in so this makes it like an antenna for 60 Hz and if I touch the RCA gold outside surface the 60 Hz is terrible! So, I am going to remove them from my board to help raise the noise resistance. I will not be using them anyway. They did something strange with the diff input on these RCA jacks. It probably works but with the outside flipped like it is I would not use the RCA use an adapter and use the 3.5mm jack. I have not found a schematic to prove this case however my multi-meter tells me the Left Positive Line on the 3.5 jack is connected to the Outside of the Left RCA plug and the same holds true on the Right side. Again, I am removing them so it is not a big deal to me. Just FYI in your use of this amplifier. Double check the RCA jacks before using them!!!

Todo bien buen sonido dentro de lo que cabe. No es sonido pro pero esta bien

Great little amp that can run on Raspberry pi projects. I made a power supply out of a USB cord for use in an Rpi. Works perfectly. Sounds great - clear and loud.

Excellent tiny amp for my arcade projects. Love the design and size. Works really well. Will certainly be buying more for future projects.

It sounds really nice and hides the frequency generated from the supplied power really will! the output of the speaker is independent of the power source which means that neither audio source nor power source need to be grounded with the same wire. would definitely recommend it!

Lo usé para un proyecto escolar con arduino y funcionó a la perfección
