This product calibrates and adjusts joystick data using chip processing to obtain the original signal, then outputs the correct signal to the handle for calibration. It allows for real-time adjustment of joystick parameters and offers good consistency in maintenance. Currently supports calibration for Hall effect joysticks and traditional carbon film joysticks. It does not correct inherent mechanical errors in the joystick itself and does not add dead zone settings. It is recommended for use with Hall effect joysticks for high longevity and precision. Due to different product batches, the appearance may vary, but this does not affect usage.
