Compact 75% Layout with Knob

The TUKO Nimbleback NB831 is an 81-key mechanical keyboard built on a 75 percent form factor. It includes a dedicated volume knob for quick audio control. Hot-swappable sockets accept three-pin and five-pin MX-style switches without soldering. The board ships with PBT keycaps and ships new.

Connectivity and Software Fit

The keyboard operates over Bluetooth, 2.4 GHz wireless and wired USB-C, and the supplier software runs on Windows 7 through 11, iOS and macOS. Users who want per-key actuation adjustment or analogue input will not find those functions here. Buyers needing a full-size layout with a separate number pad should look at a different form factor.

Hot-Swappable Switch Sockets

The PCB supports three-pin and five-pin MX-compatible switches, letting owners change feel and sound without desoldering. Six extra switches are included in the box for immediate experimentation. This single feature determines whether the board matches a builder who wants to customise switch types later.
