The ISD1820 Recording Module Voice Board is the real 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 analogue 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 allow for record, partial playback, or full playback of the message. Header pins allow for easy interface to a microcontroller and playback can be controlled with just one digital pin.
Key control recording and playback operation method: REC key: recording button, press and hold to record, release the button to stop recording; RLAYE key: trigger mode playback, click to play the current voice of the entire paragraph; PLAYL key: jog mode playback, press and hold to playback, release to stop playing; RPL jumper: loop play mode control, can be played circularly; FT jumper: through control, it allows the microphone voice directly to the speaker to playback.
Method of operation:
- REC button: record button, you can press and hold the recording, release the button to stop recording;
- RLAYE key: trigger mode playback, press will play this whole speech;
- PLAYL key: jog mode playback, press and hold until playback, release to stop playback;
- RPL Jumper: loop mode control, loop playback;
- FT Jumper: direct control, microphone voice through the speaker can playback.
Also check the ISD1820 Sound Voice Board Recording Module. It features the ISD1820 chip with an onboard microphone, allowing direct recording of approximately 10 seconds of voice. This recording/playback device offers true single-chip voice recording, non-volatile storage, and playback capabilities for 8 to 20 seconds.
