Hallpi PS4 TMR Sensor, 2 pieces. Compatible models: All genuine controllers. #NoteP4Parts (You can see various PS4 controller peripherals.) Please understand that Hall effect sensors (Hall effect sensor) and TMR sensors (TMR sensor) are different. Compared to Hall effect, it offers higher precision, lower noise, and a longer lifespan. In terms of performance: Gulikit TMR → (performance is almost the same as Hallpi) Hallpi → Ginful, FavorUnion, K-silver, and below are Hall effect. Since it's a digital system, the parts don't touch each other, so drift due to wear is less likely to occur. *Box not included. Instructions on how to use the software adjustment tool are also available on YouTube, and I will provide them in the transaction message after purchase.
