Mounting

The KB40 offers both a gasket mount and O ring mounting option, allowing users to choose between different typing feels and acoustic characteristics.

One Plate, Two Worlds

The Niuniu KB40 is built around a “one plate, two worlds” approach, offering plate and PCB compatibility for both traditional MX and electrostatic capacitive EC switches.

5 Layout Options

The KB40 centers around layout flexibility, offering five different configurations that range from familiar staggered layouts to fully ortholinear options. Each layout is determined by the selected plate, allowing users to tailor the typing experience to their preference, with additional plates available separately for future changes.
