USB Sound Card for Embedded Boards

This Wonrabai Waveshare module adds stereo audio input and output to Raspberry Pi and Jetson Nano projects over a standard USB 2.0 port. It integrates a stereo codec, an onboard microphone and a speaker header that delivers 2.6W per channel into 4 ohm loads. The board operates driver-free on Windows, Linux and Android, defaulting to a 48 KHz sample rate. Its compact dimensions are 4.3942 L x 10.6934 W x 15.6972 H centimeters.

Suitable for Makers and Voice Projects

Developers building voice assistants, intercoms or portable media players on single-board computers will benefit from the combined microphone and amplified speaker connections. The plug-and-play design avoids kernel-module troubleshooting. Buyers who need line-level RCA outputs, optical S/PDIF or multichannel surround should look at a different class of audio interface. Projects requiring battery-powered operation must supply their own power budgeting.

Default 48 KHz Sample Rate

The adapter locks to a 48 KHz default sampling frequency while also accepting rates from 8K through 44.1K such as 11.025K, 12K, 16K, 22.05K, 24K and 32K. This fixed default determines compatibility with streaming libraries and real-time voice codecs that expect 48 KHz. If your application demands a different native rate without resampling, this module will not match that requirement.

Questions about this item

How can I confirm the Wonrabai Waveshare USB Sound Card is recording and playing back at 48 KHz after plugging it in?

The device appears as a standard USB audio device in your operating system sound settings; select it as the default input and output, play a test tone or record a short clip, and verify the sample rate shown in the audio control panel reads 48 KHz.

What comes in the box with the Wonrabai Waveshare USB Sound Card and what must I supply separately?

The package includes the USB sound card board with an onboard microphone and a speaker header; you must provide a 4 Ω speaker rated for 2.6 W per channel, a USB 2.0 cable or port, and a host such as a Raspberry Pi, Jetson Nano, Windows, Linux or Android device.

Which sampling-rate setting should I choose for the Wonrabai Waveshare USB Sound Card — 8 K, 44.1 K or 48 K?

The hardware defaults to 48 KHz and also supports 8 K, 11.025 K, 12 K, 16 K, 22.05 K, 24 K, 32 K and 44.1 K; choose 48 KHz for general-purpose recording and playback unless your application specifically requires a lower rate.
