Unboxing

USB Connection

• One USB-C port.
• Comes with a braided cable that are USB-C on both ends.
• Comes with a converter for USB-C to USB-A.

Key Switches and Hot-swappable Sockets

• Many choices of mechanical key switchs.
• Hot-Swappable Key-Switch Socket

Available key switch choices from UHK:

The switch on mine is Silent Pink.

I recommend linear light switches, 35g to 45 activation force.

I recommend the Kailh BOX Switch . They are more smooth than the Cherry MX Switches.

Further, if you are used to the gamer's super light Cherry MX Red linear switches, i recommend the Silent Pink switch. It is the Kailh BOX Silent Pink Switch. It is super smooth, and super quiet. Quieter than Cherry MX Red Silent. 〔see Keyboard Key Switch Loudness Comparison〕

Keycap and Key Labels

The keycap used is PBT plastic, one of the best, with double-shot labeling tech, so key labels never wear-off.

• Keycap Material: ABS, PBT, PVC, POM
• Key Label Printing Tech

Backlight (functional coloring)

The keyboard has backlight, and the color of the light depends on the function of the key.

• white → means normal keys such as letters and numbers.
• cyan → means system modifier keys such as Shift Ctrl Alt ❖ Window ⌘ command
• orange → means UHK modifier keys such as mod Fn mouse.

And when a modifier key is pressed, other active keys are colored red (for keymap change) or blue (for key macros). If you have remapped keys, the light color changes accordingly.

This functional light coloring system is a superb design, and is also a innovation by UHK.

Turn Off Backlight, Adjust Brightness

• Backlight brightness can be adjusted, or turned off.
• They are set in the firmware, so it goes with the keyboard. (very nice)

Feet

• It comes with 4 detachable feet. You can leave them off, for a flat keyboard.
• Each feat is raisable.

You can attach them in several ways:

• In the back for traditional tilt
• In front for more ergonomic negative tilt
• Near the middle for tenting.

The design of the feet is very nice, just snap in and twist to lock.

Display

The big letters indicate current keymap. The letters can be programed to display any alphanumerics.

Programable Keys

• 32k onboard memory.
• Hardware support for QWERTY, Dvorak, Colemak layouts out of the box.
• Supports Mac or PC configuration (the difference is the position of ⌘ command/❖ Window and ⌥ option/Alt keys, and default key macros for navigating browser.).
• Advanced programability of the keys. Unlimited profiles. Macros. Special function keys. Dual role keys. For example, a key can temporarily act as Control when held down.
• Configuration for entire keyboard can be imported/exported as file, share with friends.
