Could you explain the form question about USB placement?  Isn’t that standardized for A.87 and B.87?

Some makers used the A.87 size but either used a cable that's attached via a JST connector (no usb option) or placed the usb on the other side of the board for some reason. Usually it's on the top for A.87.

What I'm more interested in is why this is offered in B.87 size when B.87 has the USB on the left

Is this going to be using custom firmware? Or something existing

some pcb changed a little using usbport under pcb. we want to fit as many case as possible so there's that option

Most of the case we know using usb port on the right side so we do it on the right. Our goal is to fit most case on this round since we don't provide a case at the moment.  ;D ;D ;D

We make our own software and firmware.

I made a mistake an had to order again ¯\_(ツ)_/¯

[YisSerL]

If I want to order this PCB for a Mira SE, which option should I choose?

[Walkerstop]

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

[maximm]

I want to order this for the Moon, what options should i choose?

[Blackhawk]

Might be interested in picking up a pcb + PC plate. Is the PC transparent or frosted?

[faxe]

Which cases does this pcb fit?

[C³—Ears]

Frosted.

[C³—Ears]

B87 size. Choose PC plate if you needed.

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

Hi could you let us know how thick the polycarbonate plates are?

[C³—Ears]

Sorry it's 1.5mm thick. Most tkl case use thick.

Wait, really? I thought both the MIRA SE and the MOON had A87 ports (on the right side of the board between the main section and the navigation cluster).

[kawasaki161]

This is exactly the problem I was going for when I asked.
It seems that they only used the B.87 size and stabilizer orientation but not the port-placement. Which makes this distinction almost useless because 95% of boards fit both without any issues. If you have the choice get B.87 size because the spacebar stabilizer orientation leads to less wobble.

[stepstone82]

hello, which will fit for orion v2 and lz-fe?
It is hard to find the information by myself

Yeah...For a lot of case, the usb port is the right. If you see the picture we post it's on the right side. And the in video we use mire se to test it and it worked.

Sorry we don't have duck orion v2 and lz-fe.

You can measure it yourself.

1,overall size

2,Esc and number row

3,usb on the upper side or under

Wait, so is this for certain because I want to make sure that if I get the B.87 for my Mech27v1 it will fit properly.

If the usb port on right side it may fit. We put the usb port on the right for B.87 since most the case we know using right side usb. Plus you should see the size picture and measure it for sure.

That's awesome can't wait!

[Okonomiyaki#2832]

Hi C3, what should I be selecting if I need a pcb to replace Moon TKL? Will the pcb fit exactly on Eve Moon?

[C³—Ears]

Hi C3, what should I be selecting if I need a pcb to replace Moon TKL? Will the pcb fit exactly on Eve Moon?

B.87 with no usb port.You have to use the daughter board in the Moon Kit.

[Okonomiyaki#2832]

Thank you!

Frosted.

Thanks! Is it possible to order two different plates with one pcb?

[iNViSiBiLiTi]

Is the spacebar wire above or below the switch? I think the TX87 is above, but other PCBs have it above.  Will that affect what plates are compatible? 

Also I'm confused on the B.87 and A.87 size.  What's the difference? I want was looking for a pcb that is the same size as the Leeku L3 pcb (TX87).  That pcb fits the Mira, Jane, and Mech27.


nevermind I figured it out.  A.87 has spacebar wire above.  B.87 has spacebare below.  USB port is in the same place.

Yes,sir. We test B.87 on Mira and Moon. It all worked.

Yes, please wirte in the form or PM me about what PC plates you want.

[C³—Ears]

[roostrc0gburn]

is either pcb compatible with SK0G?

[C³—Ears]

is either pcb compatible with SK0G?

A87 fit Skog.

[roostrc0gburn]

A87 fit Skog.

nice! is the plate confirmed to fit the bolt pattern also?

[corygrapher]

Which one should I buy for Fox Labs TIME TKL/WKL keyboard? Should I go with B87 & USB port up? Thank you.

FYI: Here is a close look at that PCB of TIME TKL (@36:00 of the video):

A87 but yeah

[romevi]

Because I'm lazy, will this work with a Jane r1?

yep

a87 top usb

Thanks! That's what I thought. Now to get a plate...

B.87 with top usb port. I am sure of this....

Thank you Puddsy,you are such a nice guy. But time do use a B87 size,this is the reason we make B87 usb port on the right side,since we know most of the B87 is using right side port...at least that's what happens in China....

[C³—Ears]

I am not sure about Jane.But we can make PC plate if you are interested(Cad file needed).

ah damn, someone told me wrong then

just FYI, both their B.87 and A.87 have the usb on the right side, only difference is the dimensions of the edge of the pcb.  B.87 has the spacebar wire under the switch, A.87 above the switch.  I would double check what you're Jane has.  If it's using a TX87 (Leeku), it should be bottom spacebar wire like my Mech27 is.  So you'd have to choose B.87

Yeah, it uses the Leeku TX87 PCB--which I'm not a fan of...
