ISD1820 Voice Recorder Module with On-Board Mic & 8Ω Speaker
The ISD1820 Voice Recorder Module is a complete audio recording and playback solution featuring an on-board electret microphone and capable of driving an external 8Ω speaker. Operating from 3V to 5V DC, it offers up to 10 seconds of non-volatile analog storage and can be controlled via manual push buttons or a microcontroller like Arduino for integration into DIY electronics, interactive projects, and simple announcement systems.
Features
- ISD1820 IC provides up to 10 seconds of high-quality, non-volatile voice recording and playback.
- Operates from a wide 3V to 5V DC range, compatible with 3.3V and 5V microcontroller logic levels.
- Integrated electret microphone and on-board circuitry to directly drive an included 8Ω 0.5W speaker.
- Features manual control buttons (Record, Play, Play-Loop) and header pins for microcontroller interface (e.g., Arduino, Raspberry Pi).
- Compact module dimensions (approx. 43mm x 34mm) for easy integration into prototypes and enclosures.

The ISD1820 module utilizes the dedicated ISD1820 voice record/playback IC, which stores audio in a specialized analog flash memory cell. This technology allows the recorded message to be retained without power, making it ideal for standalone applications. The module includes all necessary signal conditioning for the on-board electret microphone and a built-in amplifier capable of driving a small speaker.
Control is highly flexible, offering both manual operation via three tactile buttons (Record, Full Playback, and Jog Playback) and digital control through exposed header pins. Jumpers enable additional functions like playback looping and direct microphone monitoring. Its simple interface requires only a single digital I/O line from a microcontroller to trigger playback, facilitating easy integration into automated systems, interactive displays, and educational electronics kits.
