Introduction

This device is a compact voice recorder module engineered for straightforward audio recording and playback functionalities. It operates by capturing sound when a record button is pressed and stopping when released, storing up to 20 seconds of audio. Key parameters include a 16KHz sampling frequency ensuring clear sound capture, an operating voltage range of 3.3V to 5V, and the capability for up to 100,000 re-recordings. This module is well-suited for integration into DIY electronics, interactive projects, custom sound alerts, and educational tools.


Effortless Single-Button Recording

The module features an intuitive recording mechanism. Activating the record function is as simple as pressing the designated button to start capturing audio, and releasing it once the desired sound has been recorded. This user-friendly design allows for quick and easy voice or sound memo creation without complex setup.


Versatile Playback Options

With a total playback capacity of 20 seconds, this module can deliver concise audio messages or sound effects. Audio output can be achieved by connecting an 8Ω 3W speaker or an external active speaker, providing flexibility for different sound amplification needs. The 16KHz sampling frequency contributes to a clear and intelligible audio output.


Microcontroller Compatibility for Automated Playback

A key feature is its 3-pin digital interface, enabling seamless connection to Arduino-compatible microcontrollers or other digital control systems. This interface allows the playback function to be triggered programmatically, making it ideal for projects requiring automated or conditional audio responses.


Durable and Compact Design

Designed for longevity and ease of integration, the module supports up to 100,000 recording cycles, ensuring reliable performance over extended use. Its small dimensions of 37mm x 35mm (1.46 x 1.38 inches) allow for convenient placement in space-constrained applications.

Version History

V2.0 (Current Version): This version introduces the following key improvements over V1.0:

  • Increased Recording Time: Now 20 seconds, an increase from 10 seconds in V1.0.
  • Enhanced Audio Fidelity: The sampling frequency has been upgraded to 16KHz (from 6.4KHz in V1.0), resulting in significantly clearer and more detailed audio capture and playback.
  • Broader Voltage Compatibility: The operating voltage range is now 3.3V - 5V, expanded from the 5V-only limitation of V1.0, allowing for easier integration with a wider variety of microcontrollers and power systems.
  • Note: Key aspects such as the 100,000 repeatable recording cycles, physical dimensions (37mm x 35mm), and core functionalities like single-button operation and the 3-pin digital interface for microcontroller triggering, remain consistent with V1.0 and are detailed in the main product description and specifications.)
