Product Description

The KEEBD Rhymestone Split is a compact 40-key ortholinear keyboard kit designed for hobbyists who want to build and customize a split keyboard. It suits users comfortable with assembling their own device and those who prefer a minimal layout for efficient desk space use. This board is good if you want a highly customizable split keyboard with OLED displays and hot-swappable switches, but less ideal if you need a fully assembled or wireless option.

Key Features

  • Split 40% ortholinear layout offers a compact and ergonomic typing experience, reducing finger travel and promoting uniform key spacing.
  • Hot-swappable Kailh sockets allow easy switch replacement without soldering, enabling quick customization of typing feel and sound.
  • Dual .91" OLED displays provide real-time visual feedback, useful for layer indication or custom status information.
  • Includes TRS and TRRS sockets with a TRS cable for wired connectivity between halves, supporting a clean split setup.

Build Quality

  • Comes as a kit with FR4 switch plates and acrylic bottom and cover plates, balancing rigidity with lightweight construction.
  • Uses brass standoffs for stable mounting and assembly, contributing to a solid feel despite the lightweight materials.
  • Requires user-supplied Pro Micro controllers and MX switches, allowing full control over component selection.

Compatibility and Firmware

  • Precompiled firmware is available, simplifying initial setup for users familiar with keyboard programming.
  • Supports MX-compatible switches and keycaps, providing broad customization options.
  • Unknown OS compatibility specifics, but likely supports common platforms given standard controller use.

Trade-offs

  • Requires assembly and soldering for some components, which may not suit users seeking a ready-to-use keyboard.
  • No wireless connectivity, limiting use to wired setups only.
  • Minimal 40-key layout may not support all key functions without layer programming, potentially increasing learning curve.
  • Optional RGB LEDs and hot-swap headers require additional parts and setup, adding complexity.
