This product calibrates and adjusts data for the handle rocker using chip processing to obtain the rocker signal, then outputs the correct signal to the handle for calibration. It can adjust joystick parameters at any time and has good consistency in maintenance effect. Currently supports calibration of Hall induction joysticks and traditional carbon film joysticks. For mechanical faults inherent to the rocker, there is no correction effect, and the built-in program does not add any dead zone settings. It is recommended to work with the non-drift characteristics of Hall rockers to achieve high lifespan and precision requirements. Suitable for mainstream controllers, for the right side, with various wiring methods to achieve compatibility. Different batches may have different appearances, which does not affect use.
