• OSAv2:
- MOQ: 35
- MAX: Limiting the quantity to what I can handle. Not a set number but if orders pile in too quickly I may close orders in order to prevent me from being overloaded.
• OSAv2 numpads:
- MOQ: 8
- MAX: Limiting the quantity to what I can handle like the main board. If too many numpads get ordered I may close numpad orders before the main buy separately.
• There is not a hard limit per person, but please do not do "mini GB" size orders. (aka don't proxy for a region without my prior approval)
• Shipping:
• Shipping will be calculated at checkout. For international orders shipping at checkout might say USPS but shipping will actually be via UPS or DHL depending.

• R2 RGB build lubed with 204g0, using Des #3 rings and Des V1 blue domes. PBT keycaps.
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.
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:
• 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.
• keebnewb for helping with firmware guidance and quick turnaround on test firmware modifications.
• Olivia/OJ for the renders with amazing turnaround time.
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 and I wanted to do PC for v2 for a few years now.
• Can I get a dyed PC case? The buy is limited to the options mentioned here, 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 topre numpad not support 2U zero? 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.

Very excited that we're finally in the era of custom topre
ocm:
can I get a hotswap topre pcb with a pom plate, thank you
