Compact 75% Layout with Knob

The Vszerda F75 is a 75% mechanical keyboard with 81 keys and a multi-function knob. It targets gamers and typists who want a compact footprint without losing the function row or navigation cluster. The layout fits tight desk spaces while keeping dedicated arrow keys and a volume control within reach.

Hot-Swap PCB and Tri-Mode Pairing

The board uses a hot-swappable PCB that accepts both 3-pin and 5-pin switches so changes require no soldering. It connects via Bluetooth 5.0, 2.4 GHz wireless or USB-C wired and can pair with up to five devices at once. Switching between paired hosts is done by shortcut keys or the side button. A 1.8 m cable is included for wired use and charging.

Pre-Lubed Linear Switches at 55 g

The keyboard ships with pre-lubed linear switches rated at 55±3 g actuation force and 3.5 mm total travel. These switches deliver a smooth, consistent keystroke without tactile bump or click, which suits rapid gaming inputs and long typing sessions. The switch characteristics are the primary factor in deciding whether this board matches the feel you prefer.

Questions about this item

How can I confirm the 4000mAh battery is holding a charge after first setup?

Pair the keyboard via Bluetooth 5.0 or 2.4GHz wireless, then check the battery indicator in your OS; a stable reading after several hours of use shows the cell is working as intended.

What comes in the box and which items like a charging brick must I buy separately?

The package includes the keyboard, a 1.8m USB-C cable, a switch/keycap puller, two extra switches and an English manual; a USB power adapter for charging is not supplied.

Should I choose the 75% layout with 81 keys and knob or a different version?

This model is offered only as the 75% 81-key version with a rotary knob in black; there are no alternative layouts or capacities listed for this product.
