Rotary Encoder Module
Rotary Encoder Module
The Rotary Encoder Module is a versatile input device designed to detect rotational position and direction, commonly used for navigating menus, adjusting values, or controlling volume in embedded systems. Unlike a traditional potentiometer, this encoder can rotate infinitely in both directions without limits and provides digital pulse signals to represent movement.
This module includes a built-in push button switch, adding a tactile input option for selections or control toggles. Fully compatible with Arduino, Raspberry Pi, ESP32, and other microcontrollers, the encoder uses 3 signal pins (CLK, DT, and SW) and operates at 5V logic.
Key Features:
Type: Incremental rotary encoder with push-button switch
Output Signals: Two-channel quadrature output (CLK and DT) + push button (SW)
Rotation: Infinite (no mechanical stops)
Operating Voltage: 5V DC
Shaft Type: Knurled metal shaft (typically ~20mm) for knob attachment
Mounting: 5-pin interface, breadboard and PCB friendly
Durability: High mechanical life with smooth and responsive rotation
Compatibility: Works with Arduino, ESP32, STM32, Raspberry Pi, and more
