KY-023 Dual Axis XY Joystick Module — Analog X/Y + Push Button, 3.3V/5V, Arduino Compatible

Add intuitive directional control to your project with the KY-023 Dual Axis XY Joystick Module. This thumb-stick controller provides analog X and Y axis output (0–5V) for smooth, proportional movement control, plus an integrated push-button switch for mode selection or action triggers. The self-centering spring mechanism returns the stick to center when released — just like a game controller.

Connect three wires to your Arduino's analog and digital inputs, upload a few lines of code, and you have full 2D directional control with a button. No libraries required, no complex setup — it works right out of the box.

⚡ Key Features

• Dual-axis analog output: Two 10KΩ potentiometers provide smooth, proportional X and Y axis readings (0V–5V range, ~2.5V at center).
• Integrated push-button switch: Press the joystick down for a digital input — perfect for mode switching, menu selection, or action triggers. Pulls to ground when pressed.
• Self-centering: Spring-loaded mechanism returns the stick to center position when released.
• 3.3V and 5V compatible: Works with both 3.3V and 5V microcontrollers (5V recommended for full analog range).
• Simple 5-pin interface: Clearly labeled VCC, GND, VRx, VRy, and SW pins — connect directly to your microcontroller with jumper wires.
• No libraries needed: Uses standard analogRead() and digitalRead() functions — works immediately with basic Arduino code.
• Compact: Just 34mm × 26mm × 32mm — fits easily on breadboards and inside project enclosures.

🔧 How It Works

The module contains two 10KΩ potentiometers mounted at 90° to each other, connected to a thumb-stick via a gimbal mechanism. Each potentiometer acts as a voltage divider:

• Center position: Both VRx and VRy output ~2.5V (analog reading ~512 on Arduino's 10-bit ADC).
• Full left / full down: Output drops toward 0V (analog reading ~0).
• Full right / full up: Output rises toward 5V (analog reading ~1023).
• Button press: Pressing the stick down closes the SW switch, pulling the pin to GND (reads LOW with pull-up enabled).

Orientation tip: For correct X-Y orientation (X horizontal, Y vertical), mount the module with the pins facing to the left.
