LEOBOG Hi75C / Hi75c pro Barebone Kit

LEOBOG Hi75C Pro Keyboard Kit

The LEOBOG Hi75C Pro is a premium 75% custom mechanical keyboard kit designed for users who want a refined typing experience without sacrificing gaming performance or everyday functionality. With an 81-key layout, aluminum construction, gasket-mounted structure, hot-swappable PCB and tri-mode connectivity, it brings together the features enthusiasts expect from a modern custom keyboard.

Premium Aluminum Construction

The Hi75C Pro features a durable aluminum alloy case with a clean, refined finish. Its substantial construction gives the keyboard a solid, premium feel while maintaining the compact footprint of a 75% layout.

Comfortable Gasket-Mounted Typing

At the heart of the Hi75C Pro is a gasket-mounted structure, designed to provide a softer and more comfortable typing experience. PORON gaskets and multiple sound-dampening layers help reduce unwanted vibration and improve the overall acoustic profile of the keyboard.

Whether you’re typing for long hours or gaming late into the night, the gasket structure gives the board a more refined and controlled feel.

75% Layout, 81 Keys

The 75% layout keeps the essential function row, arrow keys and navigation keys while taking up significantly less desk space than a traditional full-size keyboard.

With 81 keys, the Hi75C Pro offers an excellent balance between functionality and a clean, compact setup.

Hot-Swappable PCB

The Hi75C Pro comes with a hot-swappable PCB, allowing you to change switches without soldering. It supports both 3-pin and 5-pin mechanical switches, giving you the freedom to experiment with different switches, sound profiles and typing feels.

The PCB also features south-facing per-key RGB, providing flexible lighting customization while maintaining compatibility with a wide range of keycap profiles.

Tri-Mode Connectivity

The Hi75C Pro offers three connection options:

• USB Type-C wired
• 2.4GHz wireless
• Bluetooth

This makes it suitable for both desktop gaming and multi-device setups. Switch between wired and wireless connectivity depending on your workflow.

Multifunctional Control Knob

The redesigned control knob adds convenient physical controls to the keyboard. Depending on the selected mode, it can be used to control functions such as system volume, media controls and RGB brightness/effects.

Its distinctive ruby-clear design also adds a subtle visual highlight to the keyboard.

4000mAh Battery

For wireless use, the Hi75C Pro is equipped with a 4000mAh battery, providing the capacity needed for extended wireless sessions.

Hi75C Wired Version

For users who prefer a straightforward wired setup, the LEOBOG Hi75C is also available as a wired variant.

The Hi75C retains the core design of the series, including the 75% 81-key layout, aluminum construction, gasket-mounted structure and hot-swappable PCB, while using a USB Type-C wired connection instead of the Pro’s tri-mode wireless system. The wired Hi75C does not include the Pro’s wireless battery or RGB system.
