Voice record module is base on ISD1820, which a multiple-message record/playback device. Your recordings are saved even without power due to the non-volatile storage on the ISD1820 and playback capability for 8 to 20 seconds. This module use is very easy which you could direct control by push button on board by Microcontroller such as Arduino, STM32, Chip Kit and etc.
In addition to its basic record or playback functions, The ISD1820 module offers flexible control option and integrate several useful features that make it ideal for a wide range of project. It supports multiple playback modes such as edge activated and level activated playback, and its control pin can be interfaced directly with microcontrollers or used with the onboard button for manual operation. The module also include an internal audio amplifier capable of driving a small 8Ω speaker without needing an external amplifier, and the recording duration and sampling characteristics can be adjust with simple resistor change on the board. These capabilities make the ISD1820 suitable for application like voice alerts, talking toy, DIY sound effects, and interactive prototypes.
