Official Original Arduino Modulino Knob rotary encoder module I2C control For Arduino

旋转编码器模块

支持旋转调节与按压输入，I2C 通信控制

The Modulino™ Knob is an interactive control module that combines rotary adjustment and push-button input. It uses a rotary encoder design and supports I2C communication with Arduino development boards via the Qwiic interface. It is suitable for volume adjustment, menu navigation, parameter setting, and various human-machine interaction projects.

Product features

Rotary encoder: supports clockwise and counterclockwise rotation, and can be used for operations such as value increment/decrement, volume adjustment, and menu selection.
Push-button input function: the knob integrates a push switch, enabling interactive operations such as menu confirmation and mode switching.
I2C communication interface: supports connecting to Arduino development boards via the Qwiic interface, reducing wiring complexity.
Modular design: compatible with the Arduino Modulino™ series modules, making it easy to combine with other sensors and actuators.
Wide range of applications: suitable for smart home control, robot interaction, electronic instrument parameter adjustment, and DIY maker projects.
