Whadda Audio Recording & Playback Module
Add sound to projects with the Whadda audio module. Records 20 secs, stores without power, and works with Arduino/Raspberry Pi.
The Whadda WPM449 Audio Recording Module is a unique and versatile component designed for seamless integration into a wide range of electronic projects, providing straightforward audio recording and playback capabilities. This compact module is perfect for hobbyists, educators, and developers looking to add sound to their creations without complex circuitry.
With its built-in microphone, the module can capture and store up to 20 seconds of audio in its non-volatile flash memory. This means your recordings are safely preserved even when the module is powered down, ensuring your sound clips are always ready for playback. Operation is simple and intuitive via the onboard control buttons, allowing for easy record and playback functions directly on the module.
For more advanced and automated projects, the WPM449 can be interfaced with an external microcontroller (such as an Arduino, Raspberry Pi Pico, or ESP32). This opens up a world of possibilities for triggered playback, sequenced audio, or integrating sound into interactive installations, alarms, or educational tools.
