DescriptionThe ISD1820 Recording Module with On-Board Mic and Loud Speaker is a module used for recording and playing back audio messages.
Here's an overview of the ISD1820 Recording Module:Purpose: The ISD1820 module is designed for recording and playing back audio messages. It includes an onboard microphone and loudspeaker for convenient audio recording and playback.
Functionality: It allows users to record their voice or other sounds, store the recordings in non-volatile memory, and play them back through the built-in speaker.
Audio Interface: The module provides a simple way to interact with audio content without needing complex audio processing.
Features:Audio Recording: The module allows users to record audio messages using the onboard microphone.
Non-Volatile Storage: Recordings are stored in non-volatile memory, ensuring they are retained even when power is turned off.
Audio Playback: The recorded audio messages can be played back through the module's onboard loudspeaker.
Control Interface: It typically features control buttons or pins for recording, playback, and other functions.
Voltage Regulation: Some versions of the module might include voltage regulation for stable operation.
Applications:Voice Recording: Used for recording and playing back voice messages, reminders, or announcements.
Audio Effects: Employed in projects that require adding simple sound effects or voice prompts.
Interactive Projects: Suitable for interactive projects where audio feedback enhances user experience.
Educational Demonstrations: Used to demonstrate audio recording and playback principles in educational settings.
Using the ISD1820 Recording Module:Wiring: Connect the module's pins to the appropriate pins on your microcontroller or other control devices.
Powering the Module: Provide the module with the required power supply (usually 3.3V or 5V) and ground connection.
Recording: Press the designated button to initiate recording. The microphone captures the audio input.
Playback: Press the playback button to play back the recorded audio through the onboard loudspeaker.
Considerations:Audio Quality: The audio quality might vary based on the module's components and settings.
Storage Duration: The length of the recording is often limited by the available memory on the module.

As advertised, hard to hear it. Must find an amplifier if you need louder performance.
Used as a reminder for a young person to lock door . Door activated from reed switch.
These work great. They are exactly what I wanted. I wish the cord would have been soldered on already but that’s no big deal. I may purchase more for future projects
Connected The power supply up to it ..pressed the Red button ..spoke into the mic ..pressed play .....and found it worked perfectly !! ..with better-than-expected sound , plus there was another play button for Limited play instead of having to listen to the entire recorded (up to 20 seconds) Loop ..Awesome( .... only 1 con: might be louder
Perfect for my project.
The single chip recorders arrived on time. I had used these before, so I had a head-start on setting them up. They can operate on 3.3 to 5 V dc. If you are connecting the output to an amplifier (instead of directly to a speaker) and using the same power supply DO NOT CONNECT THE NEGATIVE SPEAKER OUTPUT WIRE FROM THE RECORDER TO THE AMPLIFIER. If you do an ground loop will likely wipe out your recorder
ONLY RECEIVED 2 OF THE 3. NOT HAPPY.
arrived quickly. good product for the money. use on my train tables for sound effects. works well.
Surprisingly good sound for such a small foot print and price. It was easy to operate the recorder using the attached buttons or with an Arduino nano. Just be careful not to exceed the required voltage.
