GuliKit SD02 Electromagnetic Joystick Module for Steam Deck Repair Replacement 1. Upgrade your console with GuliKit's patented 3D electromagnetic sensors. Unlike traditional mechanical potentiometers that wear down and cause drift, our non-contact magnetic design ensures zero physical wear, eliminating stick drift, dead zones, and stuttering forever. 2. The upgraded SD02 model features pre-installed, pre-soldered thumbstick caps and capacitive touch-sensing wires. Say goodbye to complex desoldering and soldering irons! Enjoy a true drop-in, hassle-free installation that preserves original gyro-aiming and touch-sensing functions. 3. Engineered to perfectly fit all Steam Deck LCD versions. A quick hardware toggle on the back of the PCB module allows you to easily switch between Type A (MEDA chips) and Type B (MHDA chips) motherboard signals. (Please note: This kit is not compatible with the Steam Deck OLED). 4. Optimized with an upgraded ultra-low-power electronic design. This premium electromagnetic module consumes 50% less power than the older SD01 version, maximizing your handheld console's battery efficiency and giving you more game time per charge. 5. Equipped with a tiny built-in calibration switch on each module board. Simply turn on your console, press the onboard switch, and complete calibration instantly in SteamOS. Offers a precise centering return error within +-3 degree (compared to standard joysticks at +-5 degree) for butter-smooth control.
