Keyestudio ISD1820 Sound Voice Recording Playback Module With Mic Sound Audio Microphone for Arduino

The Keyestudio ISD1820 Sound Voice Recording Playback Module is an easy-to-use audio capture and playback board designed for Arduino projects. It is ideal for students, hobbyists, and makers looking to add high-quality, natural voice reproduction or megaphone functionality to their custom electronics.

High-quality voice recording

This module provides up to 10 seconds of high-quality, natural voice recording and playback. It can function as a standalone megaphone module or integrate into larger microcontroller projects.

Dual control methods

You can operate the module manually using the three onboard buttons and two DIP switches, or connect it to a microcontroller via the pin headers for programmatic control. The corresponding pin header interfaces transition between high and low logic levels depending on button presses and switch positions.

Flexible playback modes

The board supports multiple playback states, including loop playback, jog playback, and single-pass playback. These modes allow you to customise how your recorded audio is triggered and repeated.

Direct speaker output

When connected to an 8-ohm 2W speaker, the module directly plays back your recorded audio with clear sound reproduction. This makes it straightforward to add audio alerts or voice prompts to your designs.

Compact design and easy mounting

Measuring just 54 by 38 by 16mm and weighing 14.8g, this compact board easily fits into tight enclosures. It features two 3mm positioning holes to help you securely mount the module to other devices or chassis.

Low-power electrical specifications

The module operates on a DC 3-5V voltage range with a working current of 60mA and a maximum power consumption of 0.3W. It is designed to work reliably in temperatures ranging from -25 degrees Celsius to +65 degrees Celsius.
