ISD1820 Recording And Playback Module With On Board Mic and Loud Speaker

Published Updated 7 views

ISD1820 overview

The ISD1820 Recording Module Voice Board is a really easy way to add Voice Recording (and Playback) to your project. The Module can be operated directly by using the 3 Push-Buttons or with every microcontroller (ex. Arduino). A microphone is implemented directly on the board, and you can connect any 8 Ohm Speaker. Your recordings are saved even without power due to the non-volatile storage on the ISD1820.

This module uses the ISD1820 voice record and playback IC to record a single voice message of up to 10 seconds in length. The recorded message is stored in its specialized analog flash memory that will keep the message stored even when power is removed. The module includes an electret microphone to record your message and push buttons to allow for the recording, partial playback, or full playback of the message. Header pins allow for an easy interface to a microcontroller and playback can be controlled with just one digital pin.
