Voice ISD1820 blue pcb board /voice module/ recording module plate

The ISD1820 Voice Recording Module is an easy-to-use audio board designed for capturing and playing back short voice messages. Operating at 3V to 5V DC, this compact board is perfect for students, hobbyists, and makers looking to add voice prompts or sound effects to their projects.

Compact ISD1820 core

Powered by the ISD1820 chip, this module measures just 38mm by 42.5mm, making it easy to integrate into tight spaces. It operates on a standard DC voltage range of 3V to 5V.

Ten-second voice recording

The board allows you to record up to 10 seconds of high-quality, natural-sounding voice or audio. This makes it ideal for custom alerts, interactive displays, or promotional broadcasts.

Flexible playback control modes

It features multiple playback options, including loop playback, jog playback, and single-pass play. These modes can be triggered using onboard buttons or external inputs.

Microcontroller integration

The module can be controlled directly by a microcontroller. This allows you to automate recording and playback triggers in your coding and robotics projects.

Direct speaker drive capability

There is no need for an external amplifier to hear your recordings. The onboard circuitry can directly drive a small 8-ohm, 0.5W speaker.
