HW-040 360-Degree Rotary Encoder Sensor Module with Pushbutton
Incremental rotary encoder sensor module providing 20 pulses per revolution with continuous 360-degree rotation and integrated momentary push button.
HW-040 360-Degree Rotary Encoder Sensor Module with Pushbutton is an original, pre-tested electronic module designed for Arduino, ESP32, Raspberry Pi, robotics, and embedded engineering projects. Includes verified pinout compatibility and nationwide express shipping across Pakistan.
The HW-040 Rotary Encoder Module is the professional choice for human-machine interface (HMI) controls, digital audio volume knobs, and display menu navigation.
Key Engineering Features:
- Continuous 360° Rotation: Unlike analog potentiometers, it rotates infinitely in both clockwise and counter-clockwise directions.
- Tactile Detents: Distinct tactile mechanical clicks (20 pulses per full 360° rotation) allow precise parameter tuning.
- Integrated Pushbutton Switch: Press the shaft inward to click and select menu items or confirm inputs.
- Built-in Pull-Up Resistors: Onboard 10kΩ pull-up resistors on CLK and DT pins ensure clean quadrature signals.
Common Engineering Applications:
- 3D printer graphical menu navigation and click-to-select wheels
- Digital audio amplifier volume and equalizer controls
- Variable DC bench power supply voltage/current dial knobs
- CNC jog pendants and stepper manual positioning
What's Included in the Package:
- 1x HW-040 360-Degree Rotary Encoder Module with Pre-Soldered 5-Pin Header
Pinout Interfacing & Testing Guide:
Check the silkscreen pin labels (VCC, GND, SDA/SCL or I/O) and confirm whether your microcontroller uses 3.3V or 5V logic.
Wire the power, ground, and signal pins to your Arduino, ESP32, or Raspberry Pi using breadboard jumper wires.
Upload a standard test sketch via Arduino IDE or MicroPython and verify live readings on the Serial Monitor.
