The EC11 rotary encoder module is a compact input device that converts rotational motion into digital pulses, plus a built-in push button. It’s widely used in Arduino, ESP32, Raspberry Pi and embedded electronics projects for user input, menu navigation, parameter adjustment, volume control and more.
Key Features:
Type: Incremental rotary encoder with push-button – full 360° rotation without physical stops.
Outputs:
A & B channels – encoder pulse outputs for rotation detection.
C (SW) – push-button output when clicking the shaft.
Operating Voltage: 3.3 V – 5 V, compatible with most microcontrollers.
Unlimited Rotation: no end stops; continuous rotation.
Pulse Count: typically 15–20 pulses per revolution.
Connector: usually includes XH2.54 5-pin header for easy wiring.
Module Size: ~33.8 × 22.4 mm, weight ~14 g.
Overview:
A rotary encoder doesn’t measure absolute angle like a potentiometer; instead it generates pulse signals that indicate movement and direction of rotation, which a microcontroller interprets. The integrated push button adds another input option for confirming selections or triggering actions.
How It Works:
Rotating the encoder produces quadrature pulses on two output channels (A & B).
The phase relationship between these pulses tells your controller whether the knob is turned clockwise or counter-clockwise.
Pressing the encoder shaft produces a separate digital signal on the SW pin.
Typical Uses:
Arduino projects: menu control, parameter adjustment, selection knobs.
Embedded interfaces: volume knobs, encoder selection wheels, smart panels.
Robotics & DIY electronics: precise user input device.
Tip: When wiring to microcontroller GPIOs, enable pull-up resistors and handle debounce in software for clean readings from the encoder. (common practice)
