The fourth-generation high-precision Hall joystick employs electromagnetic induction technology, effectively eliminating Joy-Con wear and drift issues, providing players with a more stable gaming experience. The Hall sensor and joystick shaft feature a non-contact design, completely solving joystick wear problems, making it especially suitable for players who demand high precision in shooting games. Equipped with an intelligent Hall chip calibration, the JINGDU high-precision Hall joystick has a swing range of approximately 19°, compared to the traditional carbon film joystick's approximately 16°, offering a broader joystick response range and enhancing gaming precision. The upgraded JINGDU Hall joystick has a lifespan of about 2 million cycles, four times longer than the traditional carbon film joystick's 500,000 cycles. The integrated joystick design allows for easy installation, even for beginners, while the non-slip raised contact point design provides a tactile feel beyond traditional factory-installed joysticks.
