Product description: Chain Joystick - precise joystick with Hall effect - M5Stack U205
The Chain Joystick is a precision input module designed for advanced applications related to human-machine interaction and robot control . The device utilizes a Hall-effect joystick, which measures changes in the magnetic field instead of traditional mechanical contact. This solution ensures high accuracy, wear resistance, long service life, and high immunity to electromagnetic interference. The module supports three control axes: analog X and Y inputs and a digital Z input (button) , enabling intuitive and precise motion control. The integrated STM32G031G8U6 microcontroller is responsible for signal processing and communication, while the built-in programmable RGB LED (WS2812C) allows for status and operating mode indication, or the creation of visual interface elements.
