Description
This module is base on ISD1820, which a multiple-message record/playback device. It can offers true single-chip voice recording, no-volatile storage, and playback capability for 8 to 20 seconds. The sample is 3.2k and the total 20s for the Recorder.
This module use is very easy which you could direct control by push button on board or by Microcontroller such as Arduino, STM32, ChipKit etc. Frome these, you can easy control record , playback and repeat and so on.

Features:

• Push-button interface, playback can be edge or level activated
• Automatic power-dwon mode
• On-chip 8Ω speaker driver
• Signal 3V Power Supply
