ISD1820 3-5V VOICE MODULE RECORDING AND PLAYBACK MODULE WITH MICROPHONE AND 0.5W SPEAKER

The ISD1820 Voice Recording and Playback Module is a compact, easy-to-use audio solution designed for short voice recording applications. Operating on a 3V–5V DC supply, this module allows users to record and play back voice messages using onboard buttons or external control signals. It comes pre-equipped with an electret microphone and supports direct connection to a 0.5W speaker, making it ideal for embedded projects, DIY electronics, and interactive designs.

This module is based on the ISD1820 IC, which uses non-volatile memory, ensuring recordings are retained even when power is removed.
