The kit contains an ISD1820 voice recording module board with an onboard mic and speaker. The ISD1820 voice recording module board is a really easy way to add voice recording and playback to your project. The module can be operated using 3 push-buttons or directly with each microcontroller (i.e. 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 analog flash memory that will keep the message stored even when power is removed. Header pins allow for an easy interface to a microcontroller and playback can be controlled with just one digital pin. Arduino Uno, Raspberry pi,18650 2200mAh Li-ion Battery
