ISD1820 Voice Recording Playback Module with Speaker – Easy Audio Recording for DIY Projects

Detailed Description:
The ISD1820 Voice Recording Module is a simple and effective voice recording and playback solution for Arduino, DIY electronics, and embedded systems. It allows you to record up to 10 seconds of audio directly through the onboard microphone and play it back with a built-in pushbutton or via microcontroller signals.

This module includes an 8Ω mini speaker for immediate audio output and supports features like looped playback, momentary playback, and single-play modes. It uses non-volatile flash memory, so your recordings remain intact even when power is removed.
