This board mounts a self-oscillating piezo buzzer on a compact 22 × 22 mm PCB, giving your project an instant beep, chirp, or alarm with nothing more than a HIGH on one GPIO pin no PWM timers or audio code required. Drop it into any backplane to add audible menu clicks, countdown alerts, game feedback, or status tones in seconds. Use it standalone with any microcontroller, or snap it into the Genesis Modular system from Axiometa for plug-and-play integration. Works with Arduino IDE, MicroPython, or MicroBlocks.
