Description

Unit Joystick2 is a high-precision Hall effect joystick control unit, built with an STM32G030F6P6 main control chip and integrated firmware for joystick signal acquisition. The unit communicates via the I2C interface and supports three-axis control signal input, including analog input for the X/Y axes and digital button input for the Z axis. Unit Joystick2 uses a Hall effect joystick, achieving high-precision control by detecting magnetic field changes, offering advantages such as contactless operation, wear resistance, high accuracy, and strong anti-interference capability, ensuring product stability and long service life. Additionally, the device is equipped with a WS2812 RGB LED for status indication and interactive display, and reserves a firmware upgrade interface for the STM32, making firmware updates convenient. This product is suitable for various application scenarios such as game controllers and robot control.
