Product description: Arduino Modulino Buzzer - sound module with buzzer - Qwiic - ABX00108
The Modulino Buzzer is a compact sound module equipped with an integrated PKLCS1212E4001-R1 transducer , allowing you to quickly add acoustic signals to any project. It can be used as an alarm, event indicator, or simple sound and melody player . The module communicates via I2C and uses the popular Qwiic connector, making its integration into the Arduino ecosystem quick and seamless. Power and data transmission are handled entirely over a single cable, and the included Modulino library offers ready-made examples and templates for Arduino and MicroPython.
Arduino Modulino Buzzer - sound module with buzzer - Qwiic - ABX00108.
The Modulino Buzzer connects via a Qwiic cable to the Uno R4 WiFi board or other boards equipped with a Qwiic interface.
Main features of the module
- Built-in buzzer (PKLCS1212E4001-R1) : allows you to generate sounds, melodies and warning signals
- Qwiic connector : quick and solderless connection to Arduino boards
- I2C interface : default address 0x3C, programmable
- STM32C011F4 microcontroller : ensures stable operation and control of sound generation
- Daisy-chain : the ability to connect multiple modules on one bus
- Full Arduino and MicroPython compatibility : dedicated Modulino® library with examples
- Qwiic cable included : lets you get started right away
- Compact size : perfect for educational, IoT and mobile projects
Simple integration via Qwiic and pinouts
The Modulino Buzzer communicates with motherboards via I2C , using a convenient Qwiic connector , which significantly speeds up and simplifies module connection. The default I2C address is 0x3C, which can be changed software-defined, allowing multiple buzzers to be connected to a single bus. Alternatively, the module features soldered pins : GND, 3.3V, SDA, and SCL, enabling traditional connection to custom circuits or prototype breadboards . This flexibility makes the Modulino Buzzer suitable for both rapid prototyping and permanent solutions in IoT projects.

The module has leads in the form of solder pads that allow direct connection of wires if necessary.
Cross-platform programming and ready-made libraries
Thanks to support for the Arduino IDE, Arduino CLI , and Arduino Cloud , getting started with the Modulino Buzzer is quick and intuitive. The module is also compatible with MicroPython , making it an excellent educational and experimental tool. The dedicated Modulino library offers sample sketches for generating sound signals, notifications, and simple melodies. Addressing, frequency, and duration control are handled in a simple and accessible way, even for beginners.
Practical applications
The Modulino Buzzer is perfect for applications requiring audible signaling : notification systems, alarms, smart homes, educational projects, and interactive games. It can function as a warning signal, a confirmation sound when a button is pressed, or as a simple music module in toys and prototype devices.
