The Single-Axis Joystick Module is a 1-channel analog input module. It automatically returns to the center position. Compared to a Dual-Axis Joystick Module, the single-axis joystick moves in only one direction and outputs a single analog signal, making it ideal for use as a control lever in various scenarios that require speed control or position control with automatic centering — especially when the control logic of these motions needs to remain independent.
