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

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

Bought this for my gp star proton pack project It has good sound and a nice compact shape which is nice to be able to squeeze in Overall no complaints Many people who were using this for the same project had a issue with noise Putting a diode in series with the negative or ground connection for this unit will eliminate that humming or noise if you are powering your sound supplying device from the same power source

I am happy with this purchase.

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!

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.
