Design

Similar to our first project (Duo-S), one of the main objectives was to try out a new mounting design. Spring mounts! (let me know if there was already another board with a spring mount)

To spruce up the looks and functionality of the board, we incorporated a scroll wheel. This can be programmed to adjust volume, screen brightness etc.

Also, we strived to achieve a distinct middle layer accent piece that could go all the way around the board and to give an illusion of a case within a case.

Alignment of the plate and PCB is in-built via the alignment rails on the middle case.

Colours

After considering the IC feedback, we have decided to provide for 6 distinct colours! You may mix and match the colours amongst the 5 keyboard components. This makes for a total of 720 possible permutations!

Colours: Black, Navy, Grey, Copper, Maroon, Silver
Keyboard Components: Top Case, Middle Case, Bottom Case, Scroll Wheel, Weight
