OSAv2
by
Viktus Design
Board Background:
What is the OSAv2?
This board is the second version (hence the ‘v2’ in the
name) of the OSA which was initially a private buy in 2019
for a board “inspired” by an open source design at that
time.
What is different about v2?****
Basically everything but the basic side profile concept. It
is shorter, has thinner bezels, entirely different weight
design, and updated to be a better design all around.
The IC title says Topre, Is this true?****
Yes! I have wanted to make topre customs for many years (the
Viktus Styrka was initially planned on being one back in
2019 but sadly never happened) and about a year or more ago
I set out on the journey to make this a reality and after
multiple prototypes, I am ready to make this available!!!
This entire IC was actually typed using the prototype topre
PCB in the original OSA case, so it does indeed work and
works well!

7 degree
board angle
Type-C PCB (topside)
MX PCB with
inswitch LEDs and RGB underglow and reversible layout (2U’s
on left or right)
Topre PCB with multiple layouts and
switch housing options
Other plate options
available
~0.44 Kg w/brass plate
MX OSAv2 Layouts:
More
The MX OSAv2 PCB supports all layouts shown
above.
The mirrored left spacebar layouts (with the 2U
or 2.25U on the right with the 1U or 1.25U on the inside
instead) requires a separate plate from the non-mirrored
spacebar layout and will be available as an option. This is
nicknamed the vMatt as a friend commissioned pcbs made with
those mirrored and others liked the idea so it continues to
be offered.
PCB also supports Alps in said layouts, no
plate made available.
MX OSAv2 Numpad Layouts:
More
The MX numpad PCB supports all layouts shown
above.
The plate can be flipped to change which side
the 2U switches are on so only a single plate is needed for
either numpad layout. (obviously excluding the ability to do
all 2U options shown at the same time).
PCB also
supports Alps in said layouts, no plate made available.
Topre OSAv2 Layouts:
More
The topre OSAv2 PCB supports all layouts shown
above.
Each plate is fixed layout due to mounting and
making sure the housings stay in the right locations.
Support for “normal” topre housings from R1/R2 boards, as
well as R2 RGB housings will be available as plate options.
Buyer must decide which and make sure to buy the
corresponding plate.
All plates only support split
right shift, the 2.75U shift is PCB only as it would require
at minimum 4 more plates to be added and therefore costs
would increase for everything.
Topre OSAv2 Numpad Layouts:
More
The topre numpad PCB supports all layouts shown
above, but is subject to change depending on how feasible
the layout options are and interest levels.
Multiple
plate options will be available for housing support as
mentioned prior (“normal” and R2 RGB). Currently RGB is
limited to all 1U as the stabilizers aren’t supported with
the wire inboard due to the housing design and an outboard
wire would interfere with the case.
OSAv2 Info:
Color options:
Clear PC with sandblasted brass
plate, and weight
Clear PC with e-black brass plate,
and weight
Parts Included:
Board w/weight
Brass plate of matching finish to the weight (e-black or
sandblasted)
MX or Topre PCB
Screws and silicone
feet
Pricing:
Cost:
- OSAv2: $4XX
- OSAv2 numpad: $2XX
-
Pricing is an estimate at the moment given the unknown
level of interest. Pricing will be updated when I have a
better idea of the final quantities (if they are
updated)
PCBs: - MX PCB: TBD
- MX numpad PCB: TBD
- Topre PCB: TBD
-
Topre numpad PCB: TBD
Note: Boards include PCB/Plate of switch choice, so you can have MX or Topre included by default and you are not forced to buy MX or Topre if you only desire one option.
Note: Topre PCBs come with the hardware kits, plates do not.
Plates:
MX OSAv2 and OSAv2 Numpad: (1.5mm or 1.6mm) - Sandblasted Brass
- E-Black Brass
-
Forged Carbon Fiber
Topre OSAv2 and OSAv2 Numpad: (1.2mm) - Sandblasted Brass
- E-Black Brass
-
Limited to metal plates as the plates require tapped holes
for assembly purposes.
Quantity:
OSAv2: - max of 35
-
Subject to increase if demand shows, limiting the quantity
as the board is partially a private buy and a public buy,
so quantities are split between the two.
OSAv2 numpads: -
Not limited but the current plan is to limit to buyers of
the main boards only, but might be willing to open up to
others if enough interest is there. More interest would
also help drive the pricing down so subject to change
quite a bit.
Wrist rests:
OSAv2: -
There is a plan for wooden wrist rest and possible resin
wrist rests if the interest is there.
OSAv2 numpad: - I would like to make numpad ones available just for the sake of matching and filling in the gap if everything is on the desk at once. May not be offered if very low interest.
Timeline:
Looking at either august or
september for GB.
Depending on volume of interest
either Q2 or Q3 2023 delivery
Group buy format:
Current plan is FCFS. Subject to change possibly.
PCB Support:
PCBs will be QMK/VIA/VIAL compatible.
All
alice PCBs with topside USB Type-C that use the “standard”
alice pcb outline for fitment.
As well the MX PCBs
available in this buy will work with cases that also support
the above.
Topre PCBs may not work in all cases as the
PCB/plate/switch assemblies are 0.95mm taller and therefore
move the PCB and USB down said amount. This requires the
case to have the room designed into it for said difference.
I can’t confirm support outside the OSA (v1 or v2) cases as
I don’t have a collection of every alice to test with.
Topre Support:
PCBs will be QMK/VIA/VIAL compatible.
The PCB
is designed to work with both R1/R2 “normal” topre
housings/sliders (the typical black housings with topre
mount sliders) and novatouch (given they use the same plate
cutouts as R1/R2), as well as R2 RGB topre housings/sliders
with their own plate.
“Normal” and RGB require
separate plates for compatibility but function identically,
it just opens up the option for what the buyer decides they
would rather use for a donor and what parts.
For donor
boards, only a single TKL is needed to support both the OSA
and numpad depending on the layout (limited by 2U/stabs). So
you can get away with a single donor board or deskeys
housings/sliders/springs if those are available at the time
of building (2u housings not out and springs not available
from them yet, but niz does sell theirs on taobao)
NiZ
housings/sliders will not be supported by the included
plates for multiple reasons. The main reason is I have had
their 2019 sliders crack ePBT caps stems and would rather
not advocate for their parts in case that issue is still
present and I don’t want customers to be mad because I made
it an option. So you are going to have to make your own
plates for this if you desire NiZ at your own
risk/discretion. Another reason is they require yet another
plate cutout that is unique from “normal” and RGB and
instead of offering everything and increasing costs I am
also hesitant. The last reason is their 2021 revision
product page still uses everything from the 2019 product
page without a single revision so that makes me warry that
they actually changed anything instead of just updating the
year to make it seem updated/new.

Special Thanks:
OneCreativeMind for the help, feedback, and
inspiration along the way. As well as helping fund the
original round of prototypes.
Matt for the massive amount of help with
the PCBs and firmware, without you this literally wouldn’t
be possible.
jrfhoutx for your help
with prototypes and the MX/Alps numpad PCB as well.
FAQ:
How does the plate support R1 and R2 housings? Aren’t
they different?
R1 and R2 “normal” topre housings are the same, confirmed
with measurements in hand.
Can you release the files so I can 3D print it?
No.
Will there be an aluminum version? At the
moment there isn’t plans for it as the original OSA was
aluminum.
Can I get a dyed PC case? The public buy is
limited to the options discussed in this IC, no others will
be available.
Are deskeys housings supported? Yes, they
use the same plate cutout as R1/R2 “normal” topre so
therefore are supported.
Why didn’t you make it use a daughterboard?
Because the point was to allow support for other PCBs/plates
in my case as well as support for my parts in other cases as
much as possible.
Can you do an aluminum weight to save money?
That won’t help things as much as you expect them to,
aluminum weights don’t shave much cost.
Can you add ISO support? The alice stagger
makes it impossible to do it in ISO, the enter doesn’t sit
right and therefore would leave massive gaps and be missing
a switch entirely. This is why there is no ISO alice
board.
Why does the numpad not support 2U enter?
Due to limitations with mounting, sizing, and routing needed
for the PCB to function properly, there is no possible way
for me to include this as an option unfortunately.
Could you make the numpad use a different angle?
As it is meant to be a companion to the main board, I would
prefer it be kept looking identical to the main board rather
than making it an entirely different product.
RGB? MX has RGB, Topre will not.
Can you make it hotswap? No. Making a
hotswap PCB isn’t just throwing a socket on the PCB and
calling it a day. Hotswap requires a fresh restart for
almost the entirety of the routing and therefore is a
massive time commitment. Plus not everything needs to be
hotswap, please stop asking everyone on every board without
thinking about what you are actually asking the designer(s)
to do.
Will there be other topre plate options like
POM/PC?
As mentioned above, Plates need to have threads tapped and
therefore metal will be the only option. I am limiting to a
single material for now to make logistics easier given how
many plate options there needs to be already. Yes it is
possible to do an entirely different setup using very small
standoffs so no threads have to be tapped but that would
over complicate an already complicated GB due to options.
You can explore other materials on your own.
