Product Description

The Other 0xCB Static is a compact 40% mechanical keyboard kit designed for enthusiasts who enjoy building and customizing their own keyboards. It requires soldering and does not include switches or keycaps, making it suitable for users comfortable with DIY assembly. Its small size and flexible layout options appeal to those seeking a highly portable and personalized typing device with advanced features like an OLED display and rotary encoder.

Key Features

  • Compact 40% layout reduces desk space and enhances portability.
  • Integrated 0.91" OLED display allows for custom status indicators or animations.
  • Rotary encoder with configurable functions, defaulted to volume control, adds quick access to adjustments.
  • USB-C connection with left-mounted port improves cable routing and accessibility.
  • Supports QMK and VIA firmware, enabling extensive customization of layers, macros, and encoder behavior.
  • Flexible layout options include various bottom-row configurations and potential split spacebar setups.

Build Quality

  • PCB and switch plate made from FR4 material provide a solid base for assembly.
  • Includes 3D-printed feet that offer a 6° typing angle for ergonomic positioning.
  • Acrylic cover protects the OLED and electronics while keeping the design lightweight.
  • Optional upgrade to laser-cut stainless steel bottom and aluminum switch plate improves durability and stability.
  • Through-hole soldering required, which may be challenging for beginners.

Compatibility and Customization

  • Open-source firmware support (QMK/VIA) allows deep customization of key functions and layers.
  • Compatible with standard MX-style mechanical switches, enabling users to choose preferred switch types.
  • Switches, keycaps, stabilizers, and screws are not included, requiring separate purchase.

Trade-offs

  • Small 40% layout lacks dedicated arrow keys and function row, which may reduce efficiency for some users.
  • Assembly requires soldering skills and additional components, limiting suitability for beginners or those seeking ready-to-use keyboards.
  • Left-mounted USB-C port may not suit all cable management preferences.
