Product description: Rotary encoder, pulser, rotary encoder - DFRobot EC11
A knob in the form of an encoder together with a button, allows you to create a simple user interface. The module has three signals: A and B are the encoder output, while C is the button signal output. The encoder is equipped with XH2.54 PCB.
Encoder pinouts
The module is compatible with Arduino board. The manufacturer prepared a connectionexample and a sample program for Arduino.
| Pin | Description |
|---|---|
| VCC | Supply voltage from 3.3 V to 5 V. |
| GND | System ground. |
| A | Encoder phase A. |
| B | Encoder phase B. |
| C | Button. |
