ISD1820 Recording Module Voice Board With On Board Mic and Loud Speaker

This is the ISD1820 Recording Module Voice Board With On Board Mic and Loud Speaker. The ISD1820 Recording Module Voice Board is a really easy way to add Voice Recording (and Playback) to your project. The Module can be operated directly by using the 3 Push-Buttons or with every microcontroller (ex. Arduino). A microphone is implemented directly on the board, and you can connect any 8 Ohm Speaker. Your recordings are saved even without power due to the non-volatile storage on the ISD1820.

This module uses the ISD1820 voice record and playback IC to record a single voice message of up to 10 seconds in length. The recorded message is stored in its specialized analog flash memory that will keep the message stored even when power is removed. The module includes an electret microphone to record your message and push buttons to allow for the recording, partial playback, or full playback of the message. Header pins allow for an easy interface to a microcontroller and playback can be controlled with just one digital pin.

At the heart of the ISD1820 module lies its integrated ISD1820 chip, a specialized audio recording and playback IC. This chip is designed to capture and store audio signals digitally, allowing for high-quality recordings with minimal noise and distortion. The onboard microphone facilitates easy recording, eliminating the need for external equipment and simplifying setup.

The module’s onboard loudspeaker ensures hassle-free playback, delivering crisp and clear audio output without the need for additional amplification. Whether used for personal messages, music playback, or sound effects, the loudspeaker provides reliable performance in a compact form factor.

One of the key features of the ISD1820 module is its simplicity of operation. With just a few buttons and switches, users can record, playback, and erase audio recordings with ease. The module supports both manual and automatic recording modes, allowing for flexible control over the recording process.

In manual mode, users can initiate recording by pressing a dedicated button, while automatic mode enables hands-free recording triggered by sound detection. This functionality opens up a wide range of applications, from voice-activated devices to motion-activated alarms and interactive exhibits.

Additionally, the ISD1820 module offers built-in storage for multiple audio recordings, allowing users to store and access a library of sound clips as needed. This feature is particularly useful for applications requiring a variety of audio assets, such as educational toys, electronic gadgets, and interactive displays.

The module’s compact size and low power consumption make it ideal for integration into a wide range of electronic projects. Whether incorporated into custom-built devices or retrofitted into existing systems, the ISD1820 module provides a seamless solution for adding voice recording and playback functionality.

In summary, the ISD1820 Recording Module with onboard mic and loudspeaker is a versatile tool for audio recording and playback applications. Its compact design, ease of use, and flexible functionality make it an invaluable resource for hobbyists, educators, and electronics enthusiasts alike. With its combination of convenience and performance, the ISD1820 module opens up a world of possibilities for creative expression and innovation.

The package includes an 8 Ohm 0.5W speaker and cable which can be connected directly to the module’s speaker output.
