Product Description

The KBDFans Helios 88 is a mechanical keyboard designed for users who want a compact layout with a numpad, suitable for both typing and moderate customization. It supports both soldered and hot-swappable switches, making it a good choice for hobbyists who like to experiment with different switch types without soldering. Its solid build and multiple material options offer a stable typing platform, appealing to users who value durability and customization in their setup.

Key Features

  • Hot-swap and solder-compatible PCB allows easy switch replacement or permanent installation.
  • Multiple plate material options (Aluminum, PP, PC, POM, FR4, CF) enable users to tailor typing feel and sound.
  • Includes internal weights in aluminum or sandblasted copper, adding heft and stability to reduce movement during use.
  • Comes with a carry case and adjustable feet, enhancing portability and ergonomic positioning.

Build Quality

The case is made from aluminum, providing a sturdy and rigid frame. The keyboard uses a top mount style, which typically offers a firmer typing feel compared to gasket-mounted designs. The front badge and internal weights come in different materials and finishes, allowing some visual and tactile customization. The overall construction supports long-term use with minimal flex.

Typing Experience

The 8° typing angle and 19mm front height create a comfortable wrist position for extended typing sessions. The variety of plate materials available as add-ons lets users adjust the keyboard’s acoustics and keypress feedback. The solid case and internal weights contribute to a stable base, which can reduce unwanted noise and vibrations. Sound characteristics will vary depending on the chosen plate and switches.

Compatibility

The Helios 88 supports WK/WKL layouts, which include a numpad in a compact form factor. The PCB is compatible with VIA software, allowing users to remap keys and customize lighting if supported. It is suitable for most operating systems that support standard USB keyboards. Connectivity is wired only, with no wireless options.

Trade-offs

  • No wireless connectivity, limiting use to wired setups.
  • Top mount design may feel firmer and less cushioned compared to gasket-mounted keyboards, which some users prefer.
  • Customization beyond plate and switch options requires additional purchases, as some materials are add-ons.
