A button press can feel uncertain when the only response is a distant screen change. This module adds a short retro-style beep so an interaction also has an audible response.

After power and ground are connected, a falling edge on EN triggers the miniature piezo buzzer. EN can be linked to a button or several buttons, letting the feedback accompany an existing interface.

A 3mm mounting hole makes it easier to place the module inside an enclosure. The sound behavior is provided by the module, leaving the main project to handle the actual function of the button.

Key specifications:

• VDD/GND/EN connections

• Falling-edge trigger

• Miniature piezo buzzer

• 3mm mounting hole
