SKU CH-W62G-PATJT

Standalone sound board stores 16 MB of WAV or OGG files and plays them through 11 trigger inputs without a microcontroller

  • Product typeEngineering Development Tools
  • Stand-alone audio triggering with no microcontroller needed
  • 11 trigger inputs for buttons or switches
  • 16 MB flash storage with USB drag-and-drop loading
  • High-quality decoding handles any sample rate or stereo format
  • Runs from a 3 to 5.5 VDC battery for portable projects

Compact Stand-Alone Audio Trigger

The Adafruit Audio FX Sound Board adds sound effects to props, costumes and toys without any microcontroller or programming. It stores WAV or OGG files on 16 MB of flash and plays them through a stereo line output. Power comes from a 3 to 5.5 VDC battery, so the board runs completely on its own.

For Makers Who Need Simple Button-Activated Sound

This board suits builders who want up to 11 trigger inputs for buttons or switches and five trigger modes without writing code. It is not for projects that require more storage than 16 MB, polyphonic playback, or advanced audio processing such as mixing or DSP effects.

USB Mass Storage and Flexible Trigger Modes

The built-in USB mass storage lets you drag and drop audio files directly from a computer. Five selectable trigger types change how each button behaves, covering momentary, latching, sequential and random playback styles for varied interactive designs.

Questions about this item

What power source must I supply to run the board?

Provide any 3 to 5.5 VDC battery or regulated supply; the board has no on-board regulator and draws power directly from the connected source.

Can I keep my existing momentary buttons and use them with the 11 trigger inputs?

Yes, each of the 11 trigger pins accepts a simple switch-to-ground connection, so your current buttons work without modification.

How do I verify the board plays the correct files after I drag them onto the 16 MB flash?

Press each wired button in turn; the corresponding audio file should play immediately through the stereo line-out or headphones.
