Ever run out of pins on your (Arduino) project?

Introducing the Rotary Module, your solution for easy rotary switch connectivity in Arduino and other microcontroller projects. With just one analogue wire connection, this module simplifies the integration of a rotary switch, offering convenience and a space-saving solution.


  • Brand: Taiwan Alpha (Standard version) / Taiwan Alpha (Continuous version)
  • Compatibility: The Rotary Module is compatible with various microcontrollers, including Arduino and STM, ensuring seamless integration into your projects.
  • Easy Installation: The module comes pre-soldered for your convenience. You have the option to solder the included Molex header or directly connect wires, saving valuable space on your Arduino.
  • Simple Wiring: Connect 3V3 (or 5V for 5V processors) and ground (0V) to the module, and then connect the signal wire to an analogue pin on your Arduino. That's all it takes to use all 12 buttons! It's as easy as connecting and using a potentiometer.
  • Rotary Switch Options: Choose between two rotary switch options. The standard switch is non-continuous, requiring clockwise and counterclockwise turns to navigate positions. Alternatively, the continuous rotary switch will automatically return to position one after a full 360-degree turn.
