ISD1820 voice record and playback with speaker

This module (HCMODU0093) 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 specialised 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.

Included with this module is an 8 Ohm 0.5W speaker and cable which can be connected directly to the modules speaker output.
