Product Description

The Promotype Key Boy Advance 50 is a mechanical keyboard kit suited for hobbyists who enjoy customizing their typing experience. It offers flexibility in plate material and PCB layout, allowing users to tailor the build to their preferences. This keyboard is ideal for users comfortable assembling keyboards and selecting additional components like foam for sound dampening.

Key Features

Choice of plate material, with aluminium as the default, provides a balance of rigidity and typing feedback.
Multiple PCB layout options enable customization of key arrangement to fit different typing styles or space constraints.
Foam pack for acoustic dampening is available as an addon, giving users control over sound and typing feel.

Build Quality

The default aluminium plate contributes to a sturdy typing surface that can enhance key stability. Other plate options may offer different typing characteristics. The keyboard requires user assembly, which allows for personalized component selection but demands some technical skill.

Trade-offs

The foam pack is not included, so users seeking quieter or softer typing will need to purchase it separately.
As a kit, it is less suitable for users who prefer a ready-to-use keyboard without assembly.
Connectivity options and firmware details are unknown, which may affect compatibility with some setups.
