Product Description

The Leopold FC660M is a compact mechanical keyboard suited for users who want to save desk space without sacrificing key functionality. It fits well for typists and professionals who prefer a smaller layout with a standard ANSI key arrangement. This board is not designed for users needing hot-swappable switches or wireless connectivity.

Key Features

  • Compact layout reduces footprint while retaining essential keys, ideal for limited desk space.
  • Dip switches allow layout customization, enabling users to adjust key functions without software.
  • Equipped with genuine Cherry MX switches, offering consistent and reliable key actuation.
  • Full USB key rollover supports simultaneous key presses, beneficial for fast typing or complex input.
  • Durable PBT keycaps with double-shot legends provide long-lasting legends that resist fading.

Build Quality

  • Plate-mounted switches contribute to a stable and solid typing feel.
  • Case is constructed to balance sturdiness and portability, suitable for frequent desk setups.
  • Keycaps use PBT material, which is more resistant to wear and shine compared to ABS.

Typing Experience

  • Choice of Cherry MX switch types (Silent Red, Black, Brown, Blue, Red, Clear) allows users to select preferred tactile or auditory feedback.
  • Switches are not hot-swappable, so changing switches requires soldering skills.
  • Sound profile varies by switch type, with options ranging from quiet to clicky.

Connectivity and Compatibility

  • Wired USB connection ensures stable and low-latency input, compatible with Windows systems.
  • No wireless or Bluetooth support, limiting flexibility for mobile or multi-device use.
  • Logical layout is US QWERTY with ANSI physical layout, suitable for standard key mapping and compatibility.

Trade-offs

  • No hot-swap feature limits easy switch replacement or experimentation.
  • Lacks built-in audio or microphone ports, which some users may find limiting.
  • No wireless connectivity reduces portability for users who prefer cable-free setups.
  • Limited to a single logical layout, less ideal for users needing alternative language layouts.
