Product description: Arduino Modulino Knob - module with rotary encoder and button - Qwiic - ABX00107
The Modulino Knob is an intelligent module combining the functionality of a rotary encoder with a pushbutton , designed for parameter control, menu navigation, and adding physical interaction to electronics projects. Equipped with a PEC11J encoder and an STM32C011 microcontroller , it communicates over an I2C bus using a Qwiic connector. Powered by the Modulino library and compatible with Arduino and MicroPython, it is a versatile component of any interactive or educational system.
Arduino Modulino Knob - module with rotary encoder and button - Qwiic - ABX00107.
Rotary encoder with built-in SPST switch.
Main features of the module
- PEC11J rotary encoder with push button : precise value control and click interaction
- Communication via I2C : with default address 0x76 (software variable)
- Qwiic connector : fast, secure and solderless connection to Arduino boards
- Soldered pins : an alternative to Qwiic connections - GND, 3.3V, SDA, SCL
- Ready-made Modulino libraries : Arduino and MicroPython support with examples and templates
- Compact size : dimensions 41 x 25.36 mm, weight only 8.5 g
- Built-in STM32C011 microcontroller : manages pulse reading and button status
- Plug and play : ready to use immediately after connecting the Qwiic cable (included)
Well-thought-out connectivity and universal connections
The Modulino Knob communicates with boards like the Arduino via I2C , utilizing the Qwiic connector for quick and seamless connection. The default address of 0x76 can be easily changed via software, allowing multiple modules to be connected on a single network. For custom designs or breadboard prototyping, soldered GND, 3.3V, SDA, and SCL pins are available for mounting flexibility and compatibility with a variety of hardware solutions.

The Modulino Knob connects via Qwiic to the Arduino Uno R4 WiFi or other compatible boards. Solderable pins are also available.
Cross-platform control and easy programming
Modulino Knob supports the Arduino IDE, Arduino CLI , and Arduino Cloud environments, offering ready-made code examples for reading encoder position and button state. With support for MicroPython , the module is also ideal for educational applications and experimental projects. The official Modulino library allows even those without experience to get started quickly – with just a few lines of code, you can create your own physical knob interface.
Practical applications
The Modulino Knob is the ideal solution for projects requiring interactive control of parameters—from adjusting brightness or volume to navigating menus and user interfaces. It can be used in IoT devices, audio systems, automation, educational games, and many other interactive applications. Its rotation and click capabilities make it one of the most versatile controls available.
