Introduction
The XMMX is a Tenkeyless PCB designed to work with MX compatible switches as well as ALPS SKCL/SKCM and their clones.
The project is available opensource under a Creative Commons BY-SA 3.0 license here.

Layouts

Dots are LEDs indicators, there are two different indicators that could be populated either in switch or in their dedicated position.

Cases compatibility
This PCB is inteded to fit the Cooler Master Quickfire Rapid (not the Rapid-i) and the Filco Majestouch 2 TKL cases, although it could fit some other commercial TKL cases.
If you're looking for a way to make your TKL keyboard programmable without replacing the PCB, please have a look at bpiphany's replacement controllers.

The USB connector for this PCB is placed on the bottomside of the PCB between Esc and F1.
Alternatively, a JST ph connector could be used in the USB breakout to avoid any modification to the case.

Case name	Compatible	Notes
Cooler Master Quickfire Rapid	Yes	Tested
Cooler Master Quickfire Rapid-i	NO	Different mounting supports
GANSS G.S 87	Possible	Untested but looks identical to the Filco Majestouch 2
Filco Majestouch 1	Possible	Untested but should be identical to the Majestouch 2
Filco Majestouch 2	Yes	Tested
Filco Zero	Possible	Untested but should be identical to the Majestouch 2
iKBC G87	NO	Different mounting supports
KBParadise V80	Possible	Untested but looks identical to the Cooler Master Quickfire Rapid
KUL ES-87	NO	Different mounting supports
Norbatouch	NO	Doesn't support the QFR
WASD V2 TKL	Possible	Untested but looks identical to the Cooler Master Quickfire Rapid
YMDK CNC Case	Yes	Tested by a fellow GHer whom I provided with an ealier revision of the PCB

Parts needed
This is intended to be a DIY kit so to assemble the board yourself you need the following electronic components:

Quantity	Description	Manufacturer part number	Symbol
1	XMMX PCB
1	Atmel ATmega32u4	ATMEGA32U4-AU	U1
1	16MHz crystal	X322516MOB4SI	X1
2	22pf capacitor	CL21C220JBANNNC	C1, C2
96	1N4148 diode	1N4148W (1N4148WS would also fit)	D1 to D96
2	22 Ohm resistor	0805W8J0220T5E	R1, R2
1	1 kOhm resistor	0805W8F1001T5E	R5
3	1uF capacitor	CL21F105ZOFNNNE	C3 to C7
5	0.1uF capacitor	0805F104M500NT	C8 to C10
1	16 pins USB type-C SMD connector	TYPE-C16PIN

Please note: Part numbers are just for reference, it's not mandatory to use those, just make sure that capacitors and resistors are form factor 0805 and diodes are SOD-123.
You can use your own crystal of choice as long as it's paired with the correct capacitors.

You also need:

Two discrete LEDs and Two 0805 resistors for them;
one JST ph 5 pin connector (optional, in place of the USB connector);
a set of stabilizers;
up to 96 switches.

Firmwares

EasyAVR: Starting from v3.00.01, the XMMX is now officially supported.
QMK: XMMX is now officially supported.

Updates

v1.1: Replaced USB mini with Type-C. Fixed misalignments.

If you made this compatible with through-hole diodes and a CNT-013 Arduino Micro or Teensy 2.0 (Arduino is much cheaper) this would be a lot easier and cheaper for people to use. I for one would love this board but I can't solder SMD

Also, for the next revision, consider adding support for Alps-style stepped caps lock. That would open up a lot more keycap compatibility for those of us who want to use this with Alps switches.

I see what you mean but please understand that these are PCBs I make for myself and then release opensource hoping that it could be useful to someone else out there.
I, for one, have no interest in such modifications but the source is open to anyone for this very purpose.

Is that different from a MX stepped caps lock? If not, it's already supported.

You can get a Phantom TKL if you want to use thru-hole diodes and a Teensy controller.

The Quickfire TK has an additional column, the XMMX won't just fit. Sorry.

EasyAVR firmware now officially supports the XMMX. Big thanks to metalliqaz.

Alps stepped caps are on a different level of ****show.
1. IBM brand's stepped caps(ibm p70, some weird japanese multistation) is 1.25u mount from the left. AKA cherry compatible stepped caps
2. Alps Electric-made stepped caps(dell at101, sgi bigfoot, leading edge-2214) is 1.5u mount from the left. This mount is the more popular one among alps user.

I can take a picture later showing the differences if needed.

If you want to include all 3 mounts for caps(1.25, 1.5, and 1.75), I suggest forgoing in-switch leds and having the 1.5 mount upside down in place of the leds. The led then relocate toward the right edge of the cap.

I though of this as the only possible solution as well, and I won't then implement it.
This PCB is intended to fit a CM QFR case too so in-switch LEDs are necessary.
Also, the original idea was to convert a Filco Majestouch into a Filco Zero which features a full touch Caps Lock.
I frankly believe we can live with two different Caps Lock layouts alone. Furthermore the project is opensource for the sake of different implementations.

Hello.

I just found this thread and I was wondering if you think this pcb would fit in my current board. It uses a V80 PCB inside a case made by Vortex designed to fit into a filco I think.

Here's a photo.

Do you think it'd work?

a case made by Vortex designed to fit into a filco I think.

That case looks similar to the YMD CNC case which is compatible with this PCB.
If it supports a Filco MJ2 TKL then it will support the XMMX. You'll have to use a JST ph 5 pin connector to route your case inside the case (or solder a cable directly on the PCB) as stated in the first post.

Thank you talkingtree I will go ahead and begin printing/preparing to use this. I am very excited I've been wanting programmability on this keyboard ever since I got it it's been quite frustrating not being able to rebind caps lock as control.

I am a bit confused what you mean by having to use the 5pin connector. Could you explain more what that is for? I'd ideally not like to solder a cable directly into the pcb as a removeable cable would be ideal.

The XMMX is designed to be standalone, other than fitting some commercial cases, therefore the USB port would end up being in a unusable location for the aforementioned cases. You have certainly noticed how Filco MJ2 cables are attached to the PCB. I would the recommend the same solution, i.e. using a JST ph connector.
I hope it clarifies.

Acereconkeys · « **Reply #17 on:** Thu, 24 May 2018, 11:47:04 »

That does thank you for the reply.

I believe I will begin trying to build this PCB. It should be a fun learning experience as I've never done any kind of SMD soldering.

Thank you again for your work.

That's actually a good point. I updated the table in the first post with a symbol's list. That should answer your question.

Hello ! Is there any change I could get one of these that supports a split spacebar layout ? Something like 2.75 - 1.25 - 2.25 or 3u - 3u ? KPRepublic has something like that but I don't think the pcb fits my case : https://kprepublic.com/products/xd87-xd87-xd80-custom-mechanical-keyboard-kit80-supports-tkg-tools-support-underglow-rgb-pcb-programmed-gh80-kle

I'm the one that got the early version PCB into the YMDK case

But now I'm kinda itching for trying a split spacebar + a thick 4 - 4.5 mm Acrylic plate and put them in the same case

Thanks !
Adrian

I could have missed something but version "PCB_2020-12-10_22-51-42" looks fine. Just a note I'm using version 1.0 in a couple of boards without issue. If you have no luck finding it I could send you a extra PCB I have if you pay for shipping. Also just to be clear you will need to do all the soldering of components as I'll just be sending the bare PCB. Send me a PM if you wanna go that route.

1.1 right now has some incomplete traces, and undrilled holes among other things (ask me how I know).
I found a copy someone made of 1.1 either from before it went to WIP or that they fixed: https://easyeda.com/aarondeister99/xmmx-revised
After checking more closely I ordered that version, and can confirm it works and everything is where it should be.

Hey, I'm thinking of making this pcb for my qfr. Are the parts listed on the initial post the ones I need to purchase or is it missing some? Also, is it possible to millmax it?

The parts list is correct yes keeping in mind his other components listed below the table, except I would try a right angle jst connector.
I didn't have enough room with a normal one, so you might have better luck there.
I don't know what the specific requirements are for putting in millmaxs, but I'm betting that soldering them into the oval shaped holes would not be fun.

I don't see why not. Just to be sure, you need the other resistors in the table. But if you're not putting in LEDs, I think you can leave those 2 resistors out.

So for the 5-pin connecter, would the one I linked be correct?
