USB Audio Adapter for Raspberry Pi

The RCA Waveshare USB audio adapter adds stereo input and output to a Raspberry Pi or Jetson Nano through a standard USB 2.0 port. It operates without drivers on Windows, macOS, Linux and Android. An onboard microphone and speaker header provide direct connections for recording and playback. The module supports sampling rates from 8 kHz up to 48 kHz with a 120 decibel signal-to-noise ratio.

Suits embedded audio projects.

Makers and developers who need a simple stereo sound card for single-board computers will find this adapter fits the requirement. It delivers plug-and-play audio for voice assistants, recording tools or media playback. Builders who require multichannel surround sound, professional XLR inputs or hardware DSP processing should look at a different class of audio interface.

48 kHz maximum sampling rate decides fit

The adapter defaults to 48 kHz and also supports 44.1 kHz, 32 kHz, 24 kHz, 22.05 kHz, 16 kHz, 12 kHz, 11.025 kHz and 8 kHz rates. If your application demands sample rates higher than 48 kHz or bit depths beyond what the stereo codec provides, this module will not meet the specification.

Questions about this item

How long can I record at 48 kHz before the USB 2.0 bandwidth becomes the bottleneck?

The adapter runs at the default 48 kHz stereo rate over a standard USB 2.0 port; sustained recording is limited only by the host controller’s bulk-endpoint throughput, not by the codec itself.

Does the onboard microphone or the speaker header generate noticeable heat or fan noise during all-day operation?

The module has no active cooling and draws minimal USB bus power, so it stays silent and barely warm even with continuous playback and recording.

Which header pins must my Raspberry Pi or Jetson Nano already expose for the onboard microphone and speaker connections to work?

The board provides a dedicated microphone header and a separate speaker header; both require the corresponding 2-pin JST-style connectors on your host board to function.
