The JoyStick2 is a joystick input module featuring the STM32G030F6P6 microcontroller for control signal acquisition. It communicates via I2C and supports three-axis inputs, including analogue input for the X/Y axes and digital for the Z-axis button. Using a Hall effect joystick, It provides high-precision control through magnetic field detection, which gives benefits like non-contact operation, wear resistance, and strong anti-interference. The unit includes WS2812 RGB LEDs for status indication and a firmware upgrade interface. It\’s ideal for projects such as game controllers and robotic operations.
