Review on 🔊 DROK PAM8406 5W+5W Mini Audio Amplifier Board, 2.0 Dual Channel Class D Amp Module for DIY Speaker Sound System, DC 5V Digital Stereo Power Amplify by Beth Campbell

The amplifier arrived well packaged for postage with no traces of flux left on it. A small booklet with further information on setting up the amplifier is included in the box so that the basic setup is done one-to-one. There are additional features on board such as mute and high-low gain settings as well as external mute. The manual does not contain any additional information on how to access these functions. The ad claims it can deliver 3 watts into 4 ohms. This is possible if you calculate the RMS value from the peak voltage, in my case 40Vpp 400mV input. I haven't listened to it but I noticed when measuring that I could see the signal from both channels on both outputs, others have mentioned that this is not a stereo card. It seems a good price, it can power small speakers for DIY projects, it's well made and from a reliable supplier.
