PAM8406 Digital Amplifier module With Volume Potentiometer 5Wx2 Stereo

The PAM8406 Digital Amplifier module is a small stereo audio amplifier board based on the PAM8406 chip, with up to 5 W per channel and a built-in volume potentiometer. Power it from 5 V, feed it an audio signal from a phone, MP3 module, Arduino or ESP32, and it drives two small speakers. It is a simple way to add loud, clear sound to DIY speakers, toys and audio projects.

What's in the Box

• 1 × PAM8406 stereo amplifier module with volume potentiometer

Tip: Each speaker output is a bridged output, so never connect a speaker terminal to ground or join the left and right outputs together. Keep the supply at or below 5.5 V and share a common ground between the amplifier and the audio source.
