This audio feedback module is a compact device that delivers sound response to user interactions. It is easy to use; connect VDD and GND, and once it detects a falling edge on the EN pin, it will produce a retro-style gaming beeping sound on the miniature piezo buzzer. The EN pin can be connected to one (or multiple) buttons, providing a satisfying audio UI response. This module is useful in DIY gaming, home automation, wearables, and accessibility devices. Its 3mm mounting hole allows for mounting onto an enclosure.
