Know before you buy
This is a true DIY kit that requires soldering. You will need to solder the hotswap sockets, controllers, and other components onto the PCB yourself.
No, the kit includes the PCBs, controllers, sockets, and necessary cables, but you must purchase your own MX-style mechanical switches and keycaps separately.
Yes, the board fully supports both QMK and VIAL. VIAL is particularly recommended for this board as it allows for real-time key remapping without needing to recompile and flash the firmware.
The 34-key layout relies heavily on layers to access numbers, symbols, and function keys. It is designed for users who prefer a minimalist, ergonomic approach and are comfortable using key combinations to trigger secondary functions.
The hotswap sockets are compatible with standard MX-style mechanical switches, including 3-pin and 5-pin variants. They are not compatible with low-profile switches or optical switches.
Yes, the keyboard is compatible with Windows, macOS, and Linux. Since it uses standard USB-C connectivity and QMK/VIAL firmware, it functions as a plug-and-play HID device on all major operating systems.
