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
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 these
boards 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 easy gateway into
ortholinear, and because of its 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 two 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.)
GB Date? TBD (probably within the next 6 months, Q1 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.
VIA compatibility? Working on it. I typically don’t use VIA, so I have to read up on implementation
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 and 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.
Will you share the plate files? Maybe after first round GB concludes.
Thanks for looking!
