Description
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.
To module, added is connecting cable with the female ends.
Sensor's maintenance
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.
| Pin | Description |
|---|---|
| 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.
