Know before you buy
The FelixKeeb comes with all electronic components—including controllers, diodes, and OLED displays—professionally pre-soldered to the PCB. Your task is to assemble the physical case and install your preferred MX switches and keycaps.
No coding is required. The keyboard comes pre-flashed with VIAL firmware, which provides a user-friendly graphical interface for remapping keys, creating macros, and adjusting layers in real-time.
Yes. The controllers and displays are socketed rather than permanently soldered, allowing you to easily swap them out for future upgrades or replacements without needing to desolder components.
The FelixKeeb is compatible with standard MX-style mechanical switches. Because it features hotswap sockets, you can install or swap out your switches without the need for a soldering iron.
Transitioning to an ortholinear layout—where keys are aligned in a grid rather than staggered—typically requires a short adjustment period of a few days to a week. The split design is highly ergonomic, allowing you to position the halves at shoulder width to reduce wrist strain.
No, the FelixKeeb does not include built-in backlighting or RGB LEDs. It is designed as a minimalist, performance-focused board.
