[FU 2.3KΩ Potentiometer] – The replacement variable resistor was made by Favor Union (FU). It fits analog joysticks made by FU. This 2.3K ohm version was found in some PS5 DualSense controllers
[Compatibility] – FU sensors come in two different resistance values. This 2.3K version was printed 2K3. Make sure the value is around 2.3KΩ before ordering. (Be noticed: Choose 10KΩ version for some PS3, PS4, Nintendo Switch, Hori, PDP, BDA (Power A) controllers if you found FU joysticks inside. The potentiometer in orange made by FU is not compatible with joysticks made by ALPS, while 60% of PS5 controllers use ALPS joysticks.)
[Additional Resistor] – Complicated moving mechanism and daily wear and tear finally caused drifting. Even new sensors cannot be 100% balanced. Calibrating in controller settings might not work. We packed 10x correction resistors to solve the potential problem in hardware level. Solder one or two paralleled tiny resistors onto the potentiometer at the opposite direction against drifting. It will help correct 3 to 5 degrees drifting
[For most joystick problem] – The potentiometer sensor needs to be replaced when the controller has the problem of creeping, stuttering, a blind spot, a dead spot, a dead zone, or it wouldn't center after years of wear and tear. De-soldering the unit with only 3Pins will be a lot easier than replacing the entire joystick with as many as 14 prongs
[Reminder of Replacement] – Use a pair of pliers to separate the problem sensor off the joystick module. Try to replace the wiper first, see if it works. De-solder the sensor off the PCB. A metal pick helps to clear the holes. Soldering the new unit in is a breeze. Remember to calibrate the new control sticks in settings
