Description:
This module uses the ISD1820 voice recording and playback IC to record voice messages and playback capabilities of up to 10 seconds in length. The recorded message is stored in its specialised analog flash memory that will keep the message stored even when power is removed. The module includes an electret microphone for recording with convenient push buttons to allow for device functionality, such as record, partial playback, or full playback of the message. Header pins allow for easy interface to a microcontroller such as Arduino, Raspberry Pi, STM32, ChipKitetic plus more!, and playback can be controlled with just one digital pin.
The package comes with a single 8 Ohm, 0.5W speaker with a cable that can be connected directly to the module via the speaker output for easy sound playback.
