Product Description

The KEEBD Reviung 39 II is a compact 39-key column-staggered mechanical keyboard kit suited for hobbyists who enjoy building and customizing their own keyboards. It requires users to source and install key switches, keycaps, and a Pro Micro controller, making it a good fit for those comfortable with assembly and firmware flashing. Its small layout is ideal for users who want a minimal footprint while retaining essential keys.

Key Features

  • Hot-swap sockets allow easy switch replacement without soldering, enabling quick customization of typing feel and sound.
  • Column-staggered layout offers an alternative key arrangement that may improve ergonomics for some users.
  • Optional RGB LED rear-facing drop lights can be added for visual customization.
  • Precompiled firmware is available, but users can customize keymapping if desired.

Build Quality

  • Includes an FR4 switch plate and an acrylic bottom plate, combining rigidity with lightweight construction.
  • Acrylic controller cover is provided in a blank, clear design, offering basic protection and visibility of components.
  • Uses brass standoffs and multiple screws for stable assembly.

Typing Experience

  • Switch feel depends on user-installed MX-compatible switches, allowing full customization of tactile or linear feedback.
  • Hot-swap sockets facilitate easy experimentation with different switch types.
  • Acoustic properties will vary based on switch choice and acrylic case material, generally producing moderate sound levels.

Compatibility and Connectivity

  • Requires a Pro Micro controller, which must be installed and programmed separately.
  • Firmware supports basic keymapping and can be customized by users familiar with keyboard firmware.
  • Wired connection only, no wireless support.

Trade-offs

  • Assembly is required, including soldering for the controller unless optional hot-swap headers are used.
  • Small layout may lack some keys preferred by users needing full navigation or function clusters.
  • No built-in controller or switches, increasing setup complexity for beginners.
  • Limited case materials and design options compared to some other kits.
