I am pleased to present the result of my first custom
keyboard design project:
Krado66
A “Destaggered” 65% Ortholinear Keyboard that accepts
standard-sized keycaps
Group Buy is Live!
The idea was to take the popular 65% layout and make
it ortholinear while still be able to use standard-sized
keycaps. I also tried to maintain an aesthetically balanced
layout. I know I am not the first to make this kind of
layout (SPRH, Fold KB, ZT60, Spacey, etc.) each one was
missing something for me, so I made my own.
I have been
an ortho user for a few years now. Ortholinear boards
themselves are great, but it has always been difficult to
source keycaps because most of the beautiful custom keycap
sets out there are designed to accommodate a few of the most
common layouts in order to hit the required numbers. 40s
kits are becoming more common, but many 40% keyboards are
staggered layouts, and ortholinear 40s use smaller 1u keys.
Ortholinear keyboards with larger mods tend to use Ergodox
style 1.5u modifiers, but Ergodox kits are very niche, even
compared to 40%. As a result, Ergo kits are rarely offered
for custom sets. I would rather have keycap makers lower
their MOQ so that designers could make all kinds of rare
kits for unique and interesting custom layouts, but that
seems unlikely to happen anytime soon. I also wanted to make
this a sort of an easy gateway into ortholinear, and because
of it’s compatibility with 65% and standard ANSI layouts,
people will be able to use just about any MX-compatible
keyset that they may have lying around.
I have several
functional prototypes that I have been daily-driving for the
past few months. In fact, I am typing this post on the one
in the picture! I have a few extra functioning PCBs as
well.
PCB
Features:
QMK compatible
USB-C (Center mount)
ESD Over-Current Protection
Khail Hotswap
-
Encoder support (two locations, but only one supported at a time)
-
Stepped caps lock support (Stepped caps lock switch is south facing, normal is north facing)
Split backspace support
-
Supports three different bottom row mod/arrow cluster configurations
Layouts
The Case
The case in the picture features: -
Stacked clear acrylic with special chamfered edge and countersunk screws for a smooth surface. (Production models would have shallower countersinks for closer to flush fit.)
7o typing angle
-
Layout options to two top layers to accommodate blockers for arrow cluster and encoder(s)
High profile
-
17mm front height (desk to first chamfered edge)
-
Can accept CNC Aluminum Cone Feet
This is a fairly early stage Interest Check. I am mostly just putting out feelers to see if enough people would be interested in buying one, and to get feedback on the design. Price and expected run dates are not set yet. I have been working with a local plastics company to get the beveled and countersunk pieces. Their turnaround times have been pretty good, but their QC has been a bit lacking. Fortunately, they are responsive and will redo pieces quickly. I have also designed an FR4 skeleton case for a lower cost option if people just want to give the layout a try. I would be interested to see what people think of this board. If it does go to groupbuy stage, it would likely be a very limited run at first, as this would be my first time running a GB and I would like to be able to closely oversee quality control and keep things at a more manageable level.

Anticipated questions:
Will ISO support be offered? No. Due to the ortholinear nature of the layout, ISO enters cannot be used.
Typing test? Maybe. I do not have a fancy streamer setup. To be honest this board is more about the layout than the sound experience. It would really only be to showcase functionality.
Price? TBD (probably around or under $200 for acrylic and sub $100 for FR4 skeleton. Maybe over $100 for carbon fiber skeleton if people are interested.) $135 for acrylic case, $40 for Skeleton Case, $55 for PCB
GB Date? TBD (probably within the next 6 months, Q1 2022) July 2022
MOQ/Limit? Going to try to keep the first run around 20~25 Units for acrylic. Might go higher for skeleton.
RGB? Not in the current iteration. I am considering redesigning the pcb with a duplex matrix for added encoder and RGB underglow support for a future build, but that will take a while. Maybe in a R2, if this gets past a R1. Underglow Added. No per-key backlighting.
VIA compatibility? Working on it. I typically don’t use VIA, so I have to read up on implementation. I have added VIAL support. You can also use VIA by sideloading a .json, but rotary encoders are not supported in VIA.
Any plans for an aluminum version? Down the road, yes. If a first GB round is successful, I plan to design an aluminum board with an updated PCB. For now, I am trying to keep things simple and (relatively) inexpensive.
Will there be any other colors besides clear for the acrylic case? Maybe. If there is sufficient interest, I could see making the layer under the top most acrylic piece an accent piece as 3mm acrylic is widely available in many colors. The rest of the case, specifically the top piece would likely need to stay clear, as that is the only color available from the plastic company I am using. I don’t really want to complicate orders too much. Options for Clear, Matte Clear, Black, and White will be available.
Will you share the plate files? Maybe after first round GB concludes.
