    This new Crowtail module (Grove compatible) can simplify the connections in your project and make your life easier! Say goodbye to messy wiring and incorrect pin connections, as the Crowtail module features a standard pin arrangement and can only be plugged in one way.



    The Crowtail- Speaker is a module that consists of power amplification and voice outputs. The loudness can be adjusted by the on-board potentiometer. With different input frequencies, the speaker generated different tones. Simply code the music into your Arduino microcontrollers to DIY your own music box!

    The speaker can emit a variety of sounds like a car horn, doorbell, and ignition . The different sounds are based on the frequency of the input signal. You can supply different frequency signals to this module with Arduino. Arduino generates these signals via PWM or even digital write and delay. You can generate these signals using delay(), the speaker sound bass 1~7.


    You can use Crowtail modules with any microcontroller or HAT that comes with a Grove port. For example:
