Product Description Technical Details

The RAK18001 Buzzer Module adds compact and versatile sound output functionality to WisBlock solutions. Using the MLT-5020 buzzer from Jiangsu, it is controlled through a PWM signal from the WisBlock Core module.

With a sound output of 75 dB at 10 cm, it is ideal for use as an alarm signal, status notification, or audible user feedback. Thanks to PWM control, both pitch and loudness can be adjusted — allowing even the playback of simple melodies.

The module can be mounted in slots A, B, C, or D of the RAK19007 and requires only a single IO pin for control. Its compact size of 10 × 10 mm makes it suitable for integration into space-constrained IoT applications.
