Waveshare Pico-Audio Expansion Module For Raspberry Pi Pico - Headphone & Speaker Output With I2S Connectivity

About This Product

Raspberry Pi Pico enthusiasts, this audio expansion module from Waveshare is exactly what you need to add proper sound capabilities to your projects. It features the CS4344 low-power stereo decoder and uses I2S bus for clean audio signal transmission - way better than trying to hack together something with PWM audio. The module supports an incredible range of audio sampling rates from 8Hz all the way up to 384kHz, which covers pretty much any audio application you can imagine. What's really handy is that it allows concurrent headphone and speaker output - you get both a standard 3.5mm audio jack for headphones and dual-channel speaker headers that can drive up to 2.6W per channel. I've used it for everything from simple audio playback projects to more complex audio processing applications, and the sound quality is impressively clear with that 106 dB SNR. The 3-wire I2S connection significantly reduces electromagnetic interference, so you get clean audio without that annoying background noise. Setup is straightforward with the online resources Waveshare provides, and it works seamlessly with the Raspberry Pi Pico's I2S capabilities. The package even includes an 8?? 5W speaker to get you started right away. Whether you're building a portable music player, audio effects processor, or any project that requires quality sound output, this module delivers professional results without the complexity of designing your own audio circuit. The build quality is solid with proper connectors and clean PCB layout. It's one of those expansion boards that just works exactly as expected, making audio projects accessible even if you're not an audio engineering expert. Definitely a must-have addition to your Pico toolkit if you want to explore the world of digital audio projects!
