Dual Analog Joystick X2 Game Controller Module for Arduino & Microcontrollers, Red PCB, 2-Axis Thumbsticks with Push Button Switches, Analog Output, DIY Robotics RC Control Input Board

Overview

The JoyStick X2 dual analog controller module is a compact input board that combines two independent thumbstick joysticks on a single red PCB. Each joystick is a classic 2-axis analog mechanism designed to output variable voltages for X and Y movement, plus a built-in momentary push switch when the stick is pressed down. This makes it a practical, space-saving solution for DIY game controllers, robotics remote controls, camera pan/tilt rigs, and any project that needs smooth proportional input rather than simple on/off buttons.

Technical Details

Each joystick axis is typically implemented using a potentiometer-based mechanism. As you move the stick, the wiper position changes, producing an analog voltage between GND and VCC on the corresponding VRx/VRy output. Your microcontroller reads these voltages using an ADC channel and converts them into position values. Center position is usually around mid-supply (approximately VCC/2), but exact centering, dead zone, and full-scale range can vary by module revision and joystick tolerance. For best results, perform a quick calibration in firmware: record min/max values for each axis and apply a small deadband around center to prevent drift.

The push-button function (SW) is a momentary tactile switch integrated into each joystick. The SW pin behavior depends on the module design (often active-low when pressed with an internal or external pull-up required). Because implementations can differ, confirm the required pull-up/pull-down using the silkscreen labels and a quick continuity test, or check the seller datasheet if available.

Specifications

• Joystick count: 2 (dual analog sticks on one PCB)
• Axes per joystick: 2 (X and Y)
• Outputs per joystick: VRx (analog), VRy (analog), SW (digital switch)
• Supply voltage (VCC): varies by module revision; commonly used with 3.3V or 5V systems—verify with your controller and module markings
• Analog output range: approximately 0V to VCC (practical range and end-stops vary by joystick tolerance)
• Center output: approximately VCC/2 (may require calibration; drift/dead zone varies by unit)
• Switch type: momentary push-button (electrical behavior varies; often requires pull-up)
• Interface: direct wiring to ADC inputs (VRx/VRy) and GPIO (SW)
• PCB color: Red
• Mounting: PCB includes mounting holes (hole size/spacing varies by module revision)
• Included thumb caps: 2 (one per joystick)

Applications

• Arduino-based RC transmitters and robot controllers (tank steering, differential drive, arm control)
• Pan/tilt camera or sensor gimbal control with proportional speed mapping
• Menu navigation and UI input for DIY handheld devices
• Game controller prototypes and educational electronics labs
• Servo control, motor speed control, and cursor/position input where analog precision is needed

Integration Notes

• Wiring: Connect VCC and GND to your system supply, then connect each VRx/VRy to separate ADC-capable pins. Connect SW to a GPIO pin and enable an internal pull-up/pull-down as required by your module’s switch wiring.
• Calibration: Read center values at startup and apply a deadband to reduce jitter. Map ADC readings to your control output (e.g., -100% to +100% motor command).
• Noise handling: Use simple averaging (moving average) or low-pass filtering in firmware for smoother control, especially with long wires.
• Compatibility: Works best with controllers that have enough ADC channels (4 analog channels total for two joysticks). If your platform lacks analog inputs, you may need an external ADC.
