Physical Design & Tips
The Stylo Pro stands out by offering two distinct, interchangeable nibs designed for different workflows:
-
Writing Tip: Features a high-friction material that absorbs 90% of the impact when the tip hits the screen. It is designed to mimic the resistance and sound of a pen on paper.
-
Drawing Tip: A low-friction, durable nib that allows for fluid, uninterrupted strokes across the glass—ideal for digital painting and sketching.
Advanced Interaction Features
The OPN2504 isn't just a passive pen; it includes a variety of sensory and shortcut tools:

Vibration Feedback: Includes a linear motor that provides subtle tactile clicks or "paper-like" vibrations while writing.

-
Pinching: Trigger specific app functions.
-
Swiping: Swipe up or down on the barrel to turn pages or scroll.

Double-Tap: Quickly switch between pen and eraser tools.

-
Find My Stylo: If misplaced within 10 meters, you can use the tablet to trigger a ringtone from the stylus to locate it.
Compatibility
While primarily designed for the OnePlus Pad 4, the Stylo Pro supports certain features on the OnePlus Pad 2 depending on the software version, though the 16K pressure sensitivity is hardware-locked to newer display panels.
International devices will include chargers from their country of origin. However wall converters will be included in the package for compatibility.
