C³-LDN RGB80% PCB（Complete）

[Giorgio]

You are planning on selling a case to go with this pcb at some point? Any idea how soon?

A kit is being designed. But using type-c port.I'd say it will need at least 2 months.

That's awesome can't wait!

Hello, beside your case, that will come in a couple of months or more, what are the compatible cases actually on the market?
thanks

Well, our goal is to fit as many case as possible. So we will have A.87/B.87 mini port for sell later on as well(More expensive than GB price).And plus we can custom size for any keyboard design person/team. So i would say a lot case can be compatible later on.

Thanks, this means that I'll have to wait to buy your pcb because I have no idea of what cases are compatible.

I guess that's good for you if you do not have a case right now. This is the thing of 80%,we dont have a standard size that are compatible like 60%.

what is the different between size A and size B? im a little confused

thanks

[iNViSiBiLiTi]

what is the different between size A and size B? im a little confused

thanks

I saved a comment of myself:

A.87 has the spacebar stabilizer wire above the switch
B.87 has the spacebar stabilizer wire below the switch

Both have the USB port in what we call the A.87 layout.

If you're buying a Moon, Mira, Jane, Mech27, TX87, Acrylic Unicorn: That's B.87

If you're buying a Orion, Unicorn, Koala: That's A.87

Wow, Thanks mate. Actually,B.87 is like TX87 so this could fit in a lot of cases. And A87 is the normal size.

[YisSerL]

That is great info, iNViSiBiLiTi.

But what about USB orientation?  top/bottom?  I'm confused by that.

[C³—Ears]

That is great info, iNViSiBiLiTi.

But what about USB orientation?  top/bottom?  I'm confused by that.

If you look at the PCB you are using it's easy to find it's top/bottom. Most of the PCB are using top usb port.

pretty much everything except some GON boards, i think

Yeah,that's our goal. We dont want to do Mini port but we kind have to. it's all about compatibility！ 

[Photoelectric]

Do you have any pictures of the frosted polycarbonate plate?  Alone or over the white PCB?  I want PC plates for both MIRA SE and MOON.  Also, how thick are the PC plates?

Thank you!

[skaloola]

Is it compatible with Mars 8.0?  if so what config

[Okonomiyaki#2832]

Paid

[redbanshee]

hi C³—Ears, could you tell me the measurement of the usb port "neck" (attached image) on your a87 pcb, please?

[C³—Ears]

This should give you some information of the plate. PC plate is 1.5mm thick.You can order as many plate as you want,but you have to order at least 1 PCB.

[C³—Ears]

Sorry i don't have the size of Mars 8.0....If you have one you can measure it your self.

[C³—Ears]

hi C³—Ears, could you tell me the measurement of the usb port "neck" (attached image) on your a87 pcb, please?

What board are you looking to fit? A87 have the smaller usb port.

Thanks for that! Im trying to determine the best size for Keycult No.1, right now its looking like your B87 with the top usb is best.

TX87 is A.87

it's also a slightly different than average footprint, but the only board i've found where that matters is skog

Which PCB is compatible with an LZ CLS?

The CLS uses a TX87 PCB, so B87 with usb port on top

Me too.  If the TX87 isn't sized as A.87, the a lot of kits I thought would work with this PCB are out.  Is there a reference for this information to be sure?

c3 and others have said that if you want this as a TX87 replacement, you want what they are calling B.87, with USB top placement. I'm assuming that is correct.

This seems correct to me:

If you're buying a Moon, Mira, Jane, Mech27, TX87, Acrylic Unicorn: That's B.87

If you're buying a Orion, Unicorn, Koala: That's A.87

[Puddsy]

tbh i think my best course of action is get one and try it in my cases to see what happens cause i'm lost

I like the per switch rgb. Thats kinda cool I guess.
For me, this doesn't really fix the pain points I have with the Leeku TX87 board though.

[LifeZ]

Here,
PCBs out-line check.
The space bar stabilizer in B87 is the opposite direction.
This is VERY important.

ooohhhhk this clears it up

thanks LZ

[MajorKoos]

Thanks LZ. 

If I understand this correctly, the spacebar on the TX87 (wire at the bottom) is opposite to the B87 (wire at the top), so the stabilizers won't fit because the switch plate expects them to be facing the other way? 
Would plate mounted stabilizers work?

Correct.
and
To use the plate mount stabilizer, you need to make a separate switch plate.
You can not make combo switch plates with plate mount stabilizers.

[MajorKoos]

Got it.  Thanks LZ

[phorx]

Thanks LZ, you’ve saved me some expense and disappointment. 

If there’s a future version of this PCB that’s a drop-in replacement for the TX87, I’ll be waiting with money in hand.

[hervuli]

Uh, it would be good for C³—Ears to weigh in, because according to earlier posts the B.87 has the spacebar stab wire below the switch (and it looks that way to me based on this image of the B.87 PCB from the OP). I'm still operating on the assumption that invisibiliti's summary is correct (quoting the whole thing again here, this time including the bit on stab orientation):

I saved a comment of myself:

A.87 has the spacebar stabilizer wire above the switch

If you're buying a Orion, Unicorn, Koala: That's A.87

If this is right, seems the source of confusion is that C³—Ears is not using the standard B.87 specs? i.e. with USB port placement and also stab wire orientation I guess?

[LifeZ]

cool,
I think C³-LDN make PCB
it would be better to make it smaller than or similar to tx87.
Aluminum keyboards using b87 are very few.
Just my think...haha

yeah, the TX87 has basically become the standard

[elcubismo]

Will this fit the norbatouch case?

[Mangaboy5398]

Hello! Noob question. Are there any cases that can be bought retail that can showcase both the per switch lighting and the underglow?

[C³—Ears]

Just borrowed a TX-87 and compare with our B.87. The only difference is the stabs holes for the spacebar.

When we test this B.87 size,we used a Mira Se which using TX-87 and it worked with the same plate come from Mira Se and the PC plate we make. If the plate have enough space for the stabs,it should be fine.

Anyway,B87 size is fine for Moon,Mira,Mira Se and most custom 80%keyboard from Chinese Designer.

Anyone consider if this is a fit you can see the plate of you boards.If there's enough space for the spacebar stabs it could work. We can make sure all the Custom PC plate could work by changing it a little.

Btw,anyone know why i can't open my PM box?

[C³—Ears]

This is our PCB with OG mira se plate. It worked perfectly fine.The problem is if there is enough space for stabs hole. Where it facing is not a problem.

ok cool that means the TX87 is A.87 not B.87 and i was confused for no reason

Btw,anyone know why i can't open my PM box?

geekhack had a hardware failure and PMs are broken until they fix it

yeah ok the stabs on my mira (tx87) go the other way

but also it's about footprint, which is different on a.87 and b.87, and that matters on some cases

pretty much everything is compatible with tx87 right now, but for some reason i think you've misnamed it

gimme a bit and i'll make a smart post

[Puddsy]

It comes down to two things: plate (for stab orientation) and footprint (for whether or not it'll fit into the case)

The plate varies case by case, so it's hard to know for sure without testing. While stab orientation may not matter in the Mira, it might matter in an LZ CLS or an Eqaulz 80.

The B.87 standard is smaller than A.87, and the USB port is mounted differently on the Z-axis. This, again, comes down to a case-by-case basis. Some cases will have the USB port in a place that allows for easier access of a B.87 port, and some cases may not have the space to allow for an A.87 port.

The problem comes in with the TX87, which uses a slightly modified A.87 standard. This makes it closer to the size of a B.87 PCB, while still maintaining some aspects of an A.87 (stab orientation, USB port placement).

So, by my understanding, for any case that is confirmed to work with TX87, B.87 is the PCB to buy from this GB due to the slightly modified USB port placement to better suit A.87 cases. However, it mostly comes down to the case you're using. In some cases, the stab wires can only be used in one direction (TGR A.17 comes to mind)

This is my understanding of the situation.

[Photoelectric]

Is it possible to get a TLDR about the custom PC plate working or not working with TX87 PCB?  I'm traveling and on super slow internet, with limited time to read.  Not talking about case compatibility but rather stabilizer placement and orientation. I've been considering getting the PC plate for my MiRA SE to use with tX87 PCB.
