Rotatrix Wired Kit

Board-replacement kit · no soldering

This is the self-install kit for Rotatrix Wired — a custom circuit board that replaces the Kensington controller in a SlimBlade Pro or SlimBlade Pro EQ. The Rotatrix board also frees up the original 3-position power switch and DPI button as two extra mappable controls. Compare it with Rotatrix Hybrid on the editions page.

The base trackball is not included — you must supply the SlimBlade Pro or SlimBlade Pro EQ.

NOT COMPATIBLE with the original SlimBlade. Make sure you buy the wireless SlimBlade Pro or SlimBlade Pro EQ, even though this kit turns it into a wired Rotatrix. The internals differ.

Time required: 15 minutes
Difficulty: Easy — one delicate step
Tools needed: Screwdriver
Recommended: Plastic pry tool
