PAM8406 Pre-Soldered Stereo Class-D Audio Amplifier Module for Arduino, Raspberry Pi & ESP32

The PAM8406 Stereo Class-D Audio Amplifier Module is a compact audio amplifier module that boosts low-level stereo signals into speaker output for DIY sound systems, portable speakers, embedded audio projects, and prototyping. Built around the PAM8406 chip, it delivers efficient stereo Class-D amplification with separate left and right channels, making it useful for adding louder sound to Arduino, Raspberry Pi, ESP32, MP3 decoder boards, and other line-level audio sources. Its small size helps it fit easily into custom enclosures and space-constrained electronics that need efficient dual-channel speaker drive.
