Product Description

The Kbdcraft Adam R2 is a 60% custom mechanical keyboard kit designed for hobbyists who want a modular, upgradeable board with a distinctive retro look. It suits users interested in experimenting with switches and layouts thanks to its hot-swappable PCB and QMK firmware support. The keyboard emphasizes a solid, acoustically tuned typing experience through its unique brick-built case and gasket mounting system.

Key Features

  • Hot-swappable PCB allows easy switch changes without soldering, supporting customization and experimentation.
  • QMK firmware compatibility enables advanced key remapping and macro programming for personalized layouts.
  • Per-key RGB lighting offers customizable illumination to suit different workspaces or aesthetics.

Build Quality

  • Case constructed from 96 ABS plastic bricks, creating a thicker, denser housing than typical single-piece cases, which improves durability and sound.
  • Gasket mounting uses Poron foam to isolate the plate and case, softening keypress impact and enhancing typing acoustics.
  • Unique screwless gasket design secures the core components, reducing hardware complexity while maintaining stability.
  • White POM plate provides toughness and contributes to a rich, full sound profile.

Typing Experience

  • Gasket mount and POM plate combination produces a quieter, cushioned typing feel with improved sound dampening.
  • Plate-mount stabilizers are included, supporting stable and consistent keypresses on larger keys.

Compatibility

  • Supports a 64-key 60% layout, suitable for users comfortable with compact keyboards.
  • QMK firmware allows compatibility with multiple operating systems and extensive key customization.

Trade-offs

  • ABS brick case construction may add weight and bulk compared to typical plastic or aluminum cases.
  • Limited to wired USB-C connectivity; no wireless option is available.
  • 60% layout lacks dedicated function row and navigation keys, which may not suit all users.
