Joystick Module (PS2 Analog Joystick Module / KY-023)

This joystick module consists of a thumb-operated analog joystick mounted on a PCB. It contains two potentiometers that generate variable voltage outputs corresponding to horizontal (X-axis) and vertical (Y-axis) movement. Pressing the joystick downward activates an integrated push-button switch. The module is widely used with Arduino, ESP32, Raspberry Pi Pico, and other microcontrollers for robot control, menu navigation, game controllers, and remote-operated systems.
