HyperLine Studio is a physical control surface made for engineers, PCB designers, CAD users, and electronics makers. It is a desk device with 12 programmable mechanical keys, each planned with its own OLED display so the key labels can change depending on the selected workflow. The goal is to make CAD and electronics work faster by giving users a dedicated hardware shortcut pad for tools like EasyEDA, KiCad, Fusion 360, Altium, SolidWorks, Blender, and other apps that use keyboard shortcuts. It supports workflow profiles, USB-C, Bluetooth, media controls, and app-specific shortcut layouts. Instead of being just software or an on-screen overlay, HyperLine Studio is designed as a real physical device that users can place on their desk and use while working.
