Keyestudio ISD1820 Sound Voice Recording Playback Module With Mic Sound Audio Microphone for Arduino

After the Keyestudio ISD1820 voice recording and playback module is connected to an 8Ω 2W speaker, it can play the sound of the module.

The module uses 10 seconds of voice recording and playback, with loop playback, jog playback, single-pass playback, high quality, natural voice reproduction, can be used as a megaphone module.

When using it, we provide the DC 3-5V voltage to VCC GND, and use 3 buttons and 2 DIP switches to set the module working state. At the same time, we can connect the corresponding signal terminal to the single-chip microcomputer through the pin header interface, and then use the code to control the working state of the module.

When the 3 buttons are pressed, the corresponding pin header interface is at a high level, and after the button is released, the corresponding pin header interface is at a low level.

When two dialing codes are dialed to the ON end, the corresponding pin header interface is high level, and when the dialing terminal is dialed, the corresponding pin header interface is low level. At the same time, in order to facilitate the fixing of the module on other devices, the module comes with two positioning holes with a diameter of 3mm.
