Knob in the form of an encoder with a button that allows you to create a simple user interface. The module sends a digital signal on the SIA and SIB pins, depending on the direction of rotation. It works with the voltages from 3 V to 5.3 V.
The sensor has a 5 pin connector with digital outputs SIA, SIB and SW to be attached to the pin of the microcontroller, e.g.Arduino.
|VCC||Supply voltage from 3 V to 5.3 V.|
|GND||The ground of the system.|
|SW||An output, digital signal from the button.|
|SIA||The frequency output from the quadrature encoder A.|
|SIB||The frequencyoutput from the quadrature encoderB.|
The product is compatible with Arduino
The manufacturer has prepared a user guide along witha sample program for Arduino and STM32.
The operating principle of the encoders.

- It detects the clockwise and counterclockwise rotation
- The number of steps in 360°: 20 steps
- Button in the knob
- Module dimensions: 32 x 15 mm
