The RAK18001 WisBlock Buzzer Module is a compact audio output board built around the Jiangsu MLT-5020 buzzer element. Controlled via a PWM signal from a WisBlock Core module, it can generate tones, alerts, status beeps or simple melodies for interactive IoT devices.
Designed to fit slots A, B, C or D of the WisBlock Base Board RAK19007, the module provides a straightforward way to add audible feedback to applications such as alarms, equipment status indicators, user interaction prompts and remote notification systems. With a 75 dB output at 10 cm, it offers clear audio in compact enclosures while maintaining low power consumption.
📍 Note: The buzzer is controlled via a single IO pin, with tone and volume shaped by PWM duty cycle and frequency.
