PAM8403 Digital Audio Amplifier Module, dual channel, class D, 2.5V-5V for driving small speakers.
The PAM8403 Digital Audio Amplifier Module is a compact class D stereo amplifier board built around the PAM8403 IC, capable of driving two small speakers with clean, efficient sound reproduction. Its dual-channel design accepts both left and right audio input, making it a direct drop-in for building small speaker systems, portable audio projects, or upgrading the sound output of a DIY device.
Simply power the module (typically at 5V), feed in the audio signal, and connect two 4Ω or 8Ω speakers to the outputs to hear amplified sound – no additional circuitry required. Thanks to its high efficiency and USB-power compatibility, it consumes very little energy, and its small board footprint of just 24 x 15mm lets it fit into tight enclosures. For mono amplification needs, the LM386 Amplifier Module is a suitable alternative.
