Our best seller! We now have these back in stock. These are pairs of K-Silver TMR joystick modules for the Xbox Elite Series 2 controller. This is the best upgrade you could do for reliability and to eliminate the stick drift that these expensive controllers are known for. Again this is for a set of 2 thumbstick modules. What is TMR? It is NOT Hall effect. Compared to a Hall effect joystick, a TMR (Tunnel Magneto Resistance) generally offers significantly higher precision, better accuracy, and lower power consumption, making it the preferred choice for applications where fine control and battery life are crucial - especially in gaming controllers. TMR joysticks have a resolution of 3000 points per axis, which is 10 times more than Hall effect sensors. Similar to Hall effect, there are no parts within the module axis boards that are in contact with each other, leading to friction, wear, and ultimately stick drift. Unlike Hall effect modules, TMR will be less affected by magnetic fields such as the magnets in the thumbstick caps, which we have found to have little to no effect in the precision and calibration of the TMR modules. Due to this, TMR is the next generation of advancement in controller joystick modules, and you will see them used in even more controller applications moving forward.
