Whadda WPM449 Audio Recording & Playback Module

The Whadda WPM449 Audio Recording Module is a compact audio recording and playback module with a built-in microphone and storage for up to 20 seconds of sound. Recordings are kept in non-volatile flash memory, so they are retained when the module is powered down.

Overview

The module is designed for integration into a wide range of electronic projects, adding sound without the need for complex circuitry. Recording and playback are controlled directly on the module using onboard buttons. The WPM449 measures 43 mm (H) x 33 mm (W) x 15 mm (D) and weighs 74 grams.
