An Epic Core Inside The Keyboard

A powerful ARM architecture MCU equipped with 256K Flash will provide more flexibility for developers. The polling rate is 1000 Hz right out of the box, which makes the latency hardly noticeable even in competitive games.

OSA Profile Double-shot PBT Keycaps

These double-shot PBT keycaps have a similar height to the OEM profile and has an SA-like shape. We named it the OSA (OEM spherical angled) keycap. The PBT keycaps will provide excellent oil resistance, enhance the type feel, and prevent the legends from fading out.

Built with the Mac users’ experience in mind while still retaining compatibility for Windows devices, the Keychron V4 Max comes with a system toggle and an additional set of customized keycaps for both Windows and macOS systems. You can now save two different layouts on the keyboard, one for each system.

Gasket Mount Design

By adopting a gasket mount design along with a PC (Polycarbonate) plate, the V4 Max reduces acoustic resonance, delivering a softer and quieter typing experience with enhanced flexibility.
