DROK5W+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

Great Purchase, Thank You!

Neet little audio amp.

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 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.

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.

The unit is noisy and the knob does not turn smoothly.

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.

I used this to nake a LED flash to the rhythm of my music and it worked perfectly
