Other MKC75

The Other MKC75 is a 75% custom keyboard kit designed for enthusiasts who want a compact layout with extensive customization options. It suits users who prefer building their own keyboard with flexible mounting styles and multiple connectivity modes. This kit is good if you want to tailor typing feel and sound, support both wired and wireless setups, and customize key functions via open-source firmware. It is less ideal if you need a ready-to-use keyboard or prefer a non-customizable, plug-and-play device.

Key Features

• Three-in-One mounting system lets you choose between top mount, plate gasket mount, or PCB gasket mount, allowing adjustments to typing feel and acoustic response.
• Tri-mode PCB options support wired USB-C, Bluetooth, and 2.4 GHz wireless connections, offering flexibility for desktop and mobile use.
• QMK/VIA firmware compatibility in wired mode enables deep customization of key mapping, macros, and layers.
• Hot-swap PCBs allow easy switch replacement without soldering, supporting MX-style switches.

Build Quality

• Fully CNC-machined 6063 aluminum case provides a solid, durable base and a premium tactile feel.
• Includes multiple foam layers (IXPE, Poron) for internal sound dampening and vibration control, enhancing typing acoustics.
• Supports multiple plate options including plateless, half-plate, and standard plate to fine-tune typing feedback.
• Supports stabilizers with included O-rings, which reduce key noise and improve keypress smoothness.

Typing Experience

• Mounting and plate options let you customize the keyboard’s flex and sound profile to suit personal preferences.
• Foam layers help reduce harsh sounds and vibrations, creating a quieter and more controlled typing environment.
• Compatible with rotary knobs and LED light indicators for additional input and visual feedback, depending on configuration.

Compatibility

• Supports both ANSI and ISO layouts depending on PCB choice, accommodating different regional key arrangements.
• Requires separate MX-style switches and keycaps, as it is a barebones kit without these included.
• Firmware support limited to wired mode; wireless modes do not support QMK/VIA customization.

Trade-offs

• Being a kit, assembly and sourcing switches/keycaps are necessary, which may not suit users seeking an out-of-the-box solution.
• Wireless firmware customization is unavailable, limiting advanced key remapping on Bluetooth or 2.4 GHz connections.
• Weight is relatively high due to aluminum construction, which may reduce portability despite wireless options.
