The Dagk Alloy40 Pro is a compact 40% mechanical keyboard kit designed for users who want a small, portable board with versatile connectivity and easy switch customization. It suits hobbyists who enjoy building or modifying keyboards, and users needing multi-device support across Windows, Mac, iOS, and Android. Its layout and features favor those prioritizing portability and switch flexibility over full-size key availability.
The keyboard features an all-aluminum CNC-machined one-piece housing, providing a sturdy and durable frame. The plate is made of glass fiber, contributing to a solid typing foundation. The overall weight is light at 0.45 kg, supporting easy transport.
Equipped with DAGK customized fine-lubed satellite switches, the board offers stable and smooth keypresses, especially on larger keys. Factory lubrication reduces friction and noise, aiming for a consistent and quieter typing sound. The hot-swap sockets use Kailh sockets compatible with most mechanical switches, allowing users to tailor the feel and acoustics.
The Alloy40 Pro supports wired USB-C, 2.4 GHz wireless, and Bluetooth 5.0 connections, covering a wide range of devices and usage scenarios. It works with Windows, Mac, iOS, and Android systems without complex setup. Switching between connected devices is done via shortcut keys, simplifying multi-device workflows.
