Why Choose This Rotary Encoder Module?
- Clean Quadrature Output: On-board 10KOhm pull-up resistors on all signal lines minimize noise and contact bounce, delivering reliable CLK and DT signals for accurate direction and position decoding without external filtering components.
- Integrated Push-Button Switch: Built-in momentary switch activates when the shaft is pressed, enabling press-to-select functionality for intuitive menu navigation, parameter confirmation, and mode switching - all from a single component.
- Unlimited 360 degrees Rotation: Continuous rotation with 20 tactile detent positions per revolution provides precise incremental control for volume adjustment, value scrolling, and fine parameter tuning without mechanical end stops.
- Universal Voltage Compatibility: Operates seamlessly at both 3.3V and 5V logic levels, making it directly compatible with Arduino Uno, Nano, Mega, ESP32, ESP8266, Raspberry Pi Pico, STM32 Blue Pill, and virtually any microcontroller platform.
- Breadboard-Friendly Design: Breakout PCB with standard 2.54mm pitch pin headers plugs directly into breadboards or connects via jumper wires, enabling rapid prototyping with zero soldering required for initial testing.
- Tactile Detent Feedback: Each of the 20 click positions provides satisfying mechanical feedback, giving users a precise physical reference for each increment - essential for accurate manual input in control interfaces.
- 100% Authentic: Sourced directly from trusted, authorized suppliers with full quality verification and testing.
- Fast 1-5 days shipping: Ships from our Bengaluru warehouse with same-day dispatch for orders placed before 2 PM.
- Expert Technical Support Included: Get wiring diagrams, code examples, and troubleshooting help from our engineering team via WhatsApp or email.
Project Ideas
- Menu Navigation System: Build an intuitive user interface with an OLED or LCD display - rotate to scroll through menu items, press the shaft to select options. Perfect for settings screens in weather stations, home automation controllers, and custom instruments.
- Precision Volume & Brightness Controller: Replace potentiometers with digital rotary control for audio amplifiers, LED dimmers, or fan speed regulators. The encoder's infinite rotation and detent feedback provide smooth, precise adjustment without the wear and noise of analog pots.
- CNC & 3D Printer Manual Jog Control: Use the encoder as a manual pulse generator (MPG) for jogging CNC axes or manually feeding filament in 3D printers. Each detent can represent a precise step increment for accurate manual positioning.
- Digital Frequency & Waveform Tuner: Pair with a DDS signal generator module to dial in exact frequencies by rotating the encoder. Press to switch between coarse and fine adjustment modes for rapid yet precise frequency selection in test equipment.
- RGB LED Color Mixer: Assign each press-cycle to a different color channel (Red, Green, Blue) and rotate
