Product Description

The Leopold FC660C is a compact mechanical keyboard with electrocapacitive Topre switches. It suits users who want a smaller footprint without sacrificing key feel, such as office typists or enthusiasts who prefer a quieter, tactile experience. Its US QWERTY ANSI layout and layer-accessible function row offer a balance between space saving and functionality.

Key Features

  • Electrocapacitive Topre switches provide a tactile, quiet typing experience with a smooth keypress feel.
  • Compact 65% layout reduces desk space while retaining arrow keys and navigation functions via layers.
  • Dip switches allow customization of layout options, giving some flexibility without software.
  • PBT keycaps with dye-sublimated legends improve durability and resist wear over time.

Build Quality

  • Plate-mounted switches enhance stability and consistent keypress feel.
  • Solid black case with a sturdy construction supports long-term use.
  • Keycap colors are blue and grey with black legends positioned on top for clear visibility.

Connectivity and Compatibility

  • Wired USB connection ensures reliable input without latency concerns.
  • Compatible with Windows but lacks official support for Mac and Linux systems.
  • No multimedia keys or audio ports, so external controls are needed for sound management.

Trade-offs

  • Limited to 6-key rollover, which may affect users needing full N-key rollover for complex input.
  • No hot-swappable switches, so switch replacement requires soldering skills.
  • Absence of dedicated function keys may slow workflows for users reliant on these keys.
  • Mac and Linux users may face compatibility issues or require workarounds.
