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

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

Nice little amp. Does exactly what it promises. It would be nice to have a detachable pot for easier installation. There is no startup delay circuit, so when I turn it on with the pot there is a huge static boom which is a bit scary. Overall it is a solid component for any and all DIY project that needs to boost the audio out to drive a pair of speakers.

I’ve bought several of these tiny class D amps for tinkering and faffing purposes, starting with the pam8610, which also has quite a nice sound to it, but the lower power 8406 contained in this board has really made made quite an impression. I wanted something to drive really sensitive open baffle speakers, and being terminally short of cash a tube amp was out of the question. With this wee feller, my zenith cz49s come alive and fill my world with beautiful music. The documentation says that this is capable of being used as a class AB amp, but doesn’t say how. The 5v rating is good because you can plug it into a usb cube phone charger and not have to worry about a power brick. I will try it out with more demanding speakers, but for now this is superb!

I have actually ordered this amplifier board for a couple of different DIY projects including a amplified speaker box, and a home arcade. The board is easy to hook up and well labeled for all the connections on both sides of the board. It does not come with a 5 volt power supply, and it of course it is not an audiophile quality piece of hardware, but for small DIY projects it is pretty solid. I also like that the volume control has an off position, which not always the case for all of these type of audio boards.

I love this product, easy to use but had to give it three stars because for the first 20 minutes I use it, it turns off every 3-5 minutes then again at random.

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

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.

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

I'm using this with a Raspberry Pi 4. It worked perfectly, and really amplified the input signal, as long as the input was strong enough. There are extra features I didn't realize it had, like switching amplifier type. I didn't use these, but I appreciate it an option.
