2 Pieces Audio Amplifier Board Pam8406 Mini Amplifier Board 5v, 5w+5w Module, Digital Power Module Class D 2.0 Dual Channel Audio Stereo Amplify for DIY Sound System

Its basically plug and play, easy to use and works great!!

Excellent little 3watt stereo amplifier board I use it to buffer and amplify low current 5 volt sound outputs from my Arduino Uno to drive s small 8 Ohm speaker. Very pleased with its ability to input music from a Kindle output jack.

low distortion and high power with good price.. cant beat it. thank youvery rare does anything worth buying come from china. but this amp is worth it..

Used for 3 wired sets of headphones for TV. Big sound quality improvement over previous use of same headphones using Bluetooth. My biggest complaints are (1. The use of terminal strips for 5vdc power and headphone output. Typical barrel connector and 3.5 audio connector would have been much better. Also all of the hold down screws on the terminal strips on all 3 amps would strip when I tried to tighten them down. I ended up soldering those connections to the pins on the back of the board. (2. The volume stem has a tab that sticks up too high. It will not allow the supplied washer to lay flat. I had to file it down and also file away one side of the washer. (3. The plastic knobs are small and the striations run around the knob horizontally rather than vertically which would allow for better purchase. I will probably swap the knobs out when I find a better option . One installed however all three of us really like this update.

Out of the box one board didn't work and the other one had terrible low volume audio.Look for something else.

nicely made, great amplification, easy to hook up

I wired these up exactly according to the diagram. LED turns on, but sound. Tried several different components which work fine on their own with other devices. No tech support available. Would not recommend.

Perfect for small electronics projects. Very well made.
