Gravity: Voice Recorder Module (WTR096 V2.0, 20s, 16KHz)

The Gravity WTR096 V2.0 Voice Recorder Module is a compact audio capture and playback board designed for embedded electronics projects. It provides a simple way for students, hobbyists, and makers to integrate voice cues and sound effects into microcontroller builds.

Twenty-second audio storage

The module features built-in storage capable of holding up to 20 seconds of recorded audio. This provides ample space for short sound effects, interactive spoken prompts, or warning notifications.

Sixteen-kilohertz sampling rate

Audio is processed at a 16KHz sampling rate to maintain clear and intelligible speech reproduction. This ensures sound cues and voice recordings remain easy to understand in project environments.

Three-pin digital interface

Equipped with a standard 3-pin Gravity digital connector, the module links directly to compatible microcontroller shields. This pinout simplifies wiring and accelerates the prototyping process.

Embedded playback and alerts

Engineered for embedded applications, the board reliably triggers stored audio playback for automated systems. It serves as a practical sound alert module for robotics, interactive art, and monitoring devices.
