Passive Buzzer Module (3.3V-5V) mini development board The module comes fully assembledThis PCB Mounted Passive Buzzer Module is designed to produce a variety of sound tones depending on the input frequency. Capable of generating tones between 1. 5 to 2. 5 kHz, it can be switched on and off at different frequencies using either delays or PWM signals. With its compact size and low power consumption, this module is perfect for adding noise to your electronics projects. It is compatible with Arduino boards and other microcontrollers,
