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 Ricky Pee

The amplifier arrived in the mail well packaged and without any traces of flux. A small booklet is included in the box with more information on how to set up the amp so the basic setup is one to one, there are additional features on the 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 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.
