The Mechboards CFTKB Mysterium V1 is a DIY mechanical keyboard kit suited for hobbyists and enthusiasts comfortable with soldering and custom builds. It supports both ANSI and ISO layouts, offering flexibility for different regional key arrangements. This kit is best for users who want control over their keyboard assembly and customization but have experience with soldering, especially given the challenging USB-C connector.
The kit uses FR4 material for both the switch plate and bottom plate, which offers rigidity and durability. The included screws and standoffs differ slightly from the original BOM but maintain structural integrity. Rubber feet help stabilize the keyboard on surfaces. The USB-C connector is noted as difficult to solder, so this kit is recommended for users with soldering experience.
The PCB supports both ANSI and ISO layouts, making it adaptable to different keyboard standards. The pre-installed bootloader on the controller facilitates firmware flashing and key remapping. Compatibility with operating systems depends on the firmware used, which is not specified here.
