Dual Axis XY Joystick Module

Dual Axis XY Joystick Module – Analog Position Sensor with Push Button (KY-023)

The Dual Axis XY Joystick Module, commonly known as the PS2 Joystick or KY-023 module, is a compact and reliable input device designed for two-dimensional motion control. It integrates two perpendicular 10 kΩ potentiometers to measure movement along the X-axis and Y-axis, converting physical joystick deflection into proportional analog voltage signals (VRx and VRy).

When connected to a microcontroller’s Analog-to-Digital Converter (ADC), the joystick outputs a centered voltage of approximately VCC/2 (≈2.5 V at 5 V supply), scaling smoothly from 0 V to VCC as the joystick is moved to its extremes. In addition, the module includes an integrated momentary push-button switch (SW) that activates when the joystick is pressed downward, providing a convenient third digital input (Z-axis). The self-centering spring mechanism ensures automatic return to the neutral position when released.

🔧 Key Features

• Input Type: Dual-axis analog position sensing (X and Y) with a digital push-button (Z-axis).
• Sensing Elements: Two 10 kΩ potentiometers configured as voltage dividers.
• Analog Outputs:VRx and VRy provide 0 V to VCC output (centered at VCC/2).
• Digital Output:SW pin is active-LOW when the joystick is pressed.
• Mechanical Design: Spring-loaded auto-return to center for precise control.
• Wide Compatibility: Operates reliably with both 3.3 V and 5 V logic systems.

💡 Applications

• Remote control for robots, rovers, and RC vehicles.
• Pan-tilt camera control and robotic arm positioning.
• Custom game controllers and simulation interfaces.
• User navigation for LCD, OLED, and GUI-based menus.
