The module comes with the functions of 10 seconds of voice recording and playback, loop playback, single-pass playback, high quality and natural speech reduction and can be used as a megaphone module. Connected to an 8Ω 0.5W speaker, it can play the sound of the 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.
