How much would your boards cost?
I'm still waiting on USB C connectors :'(. I currently have a couple left though. They'd be $25 a piece + shipping flashed and ready to go.

JLCPCB is pretty much idiot proof (by some miracle even I figured it out), so I'd totally recommend going that route if you don't mind getting some extras.

I have waited ages to see if stuff comes back in stock please can I buy some boards from you? I will then just get the USB C connector. How do you want to go about it?
Feel free to PM me. The C connectors are on their way (They've been in the US since the 16th, so I think they'll be arriving any day now).
I also have some green or blue LEDs that I can throw in too for the lock lights.

Hey folks,

This is my first post actually, so hello for starters!

I've been following (lurking around) this project pretty closely and took the plunge on some PCBs with black solder mask to fit into a case I had lying around.

I've got three left (one went disastrously, I'll stick to through-hole from now on thank you very much), so thought I'd offer on here. They aren't assembled, but the component cost only came in at around £4 per PCB at LCSC.

If you're interested in one, fire us a message. I'm in the UK by the way.

Cheers all, hope to see you around.

P.S. This project is awesome. Good job :)

I can safely say the switch alignment holes are painfully tight
I looked closer into the matter and found out that they were actually smaller than spec. I'm fixing it soon.

Edit: fixed.

I think I may have killed one (read several :confused:) in the process of soldering the USB C connectors, any idea what would have been damaged if I shorted the connector? What do you think I would need to replace to get it working again?

I was able to flash one just gluing the USB C connector down, but after the connector popped up it no longer works, and the other, I originally hardwired, but then tried to attach a connector, and it also no longer works... did I short something out? These connectors have been surprisingly difficult to attach.

Likely none.

Depends on how bad the connector is now. Can you show a picture?

I think it's slightly rotated, and the plastic part got a bit melted.

Would the hardwire point work with a JST daughter board or something? I have at least one thats pretty messed up.

Definetely. Even a different connector. That's why I put a breakout there.

Is there a specific header spacing/connector that fits those pins? I remember seeing something in the BOM, but there are two wiring points, one by the atmega and one under the USB C connector.


Any idea what components might have failed if my soldering iron was too hot or I shorted something?

Anything with 2,54mm spacing.

Iron was definetely too hot. Some flux would also help.

so 2.54mm spacing for the header that is near the Atmega32u4? The header below the USB connector appears to have narrower spacing

Iron was definetely too hot. Some flux would also help.

I actually did use flux, but its the thicker paste meant to be used for sweating pipes (I really need some liquid flux and a pointier soldering iron tip). I found it was really easy to use too much solder and short all the connections, so I had to go back and remove extra solder.

Is is possible I burned the atmega32u4 or one of the capacitors in the process?

What iron temperature do you use?

The six pads header? That's the ISP to flash the bootloader. Don't mess with that.

Could be 2mm then. I forgot, but you can solder live wires to it.

I don't think you could do that without actually burning the PCB as well.

Between 250 and 300 °C works fine for me.

Hi, thanks for your work! This is one my favorite projects on GH and I'm eager to build some boards using your PCB.
What is the difference between rev 1 and rev 2? Is the alignment-hole sizing fixed in both revs?

Rev. 2 gets RGB LED indicators, an additional switch support and USB type-C socket.
Side pins holes are fixed in Rev. 2 only.
I've ordered a batch of PCBs for myself so I'll be testing them soon. I've also changed the matrix but I'm yet to update the code.

First of all, thanks for putting work into this project and for posting it.  I was looking for a 100% PCB, and this is exactly what I was looking for.  I ordered and have received a few Rev. 2 PCBs.  I'm just waiting on some of the components.

I have a question.  In looking at the schematic, I don't see any current limiting resistors on the RGB LEDs.  Are they not necessary?

In my understanding the driver inside the package will handle that. You do need a 0.1uF capacitor for each one of the LEDs.
Be aware that the new revision is made out of a different matrix and the code on QMK github won't work. I've ordered myself some PCBs but they're suffering a long delay for some reason.
I'll try to update the code as soon as possible.

My Rev 2 PCB is soldered, with the exception of the switches and LEDs (I bought the wrong ones).  I have QMK up and running, but I think I may have found a bug.  The switch positioned between S101 and S102 is wired to column 5, so it registers as a right bracket.  I admit that I could be wrong that this is a bug because this is my first time building a keyboard.

As stated in my last post. That matrix is for Rev. 1 and I've not uploaded a Rev. 2 code yet because I was waiting for my PCBs to arrive but they were greatly delayed and yet to arrive.
I'll try to provide an untested code this weekend. Have a little patience please.

I didn't explain myself very well.  I didn't use the Rev1 firmware that comes packaged with QMK.  I built my own QMK firmware using kbfirmware.com.  Like you, I thought that I had simply assigned the keys to the wrong pins on the microcrontroller, meaning that I had a software issue.  However, after a lot of troubleshooting, I opened up the schematic and board on EasyEda, and I think there is a mistake in the matrix.

I'm referring to the switch physically positioned between S101 and S102 on the board.  On the schematic, it's called "6.25u Space."  I'll call it S101.5.  S101.5's row pin is wired in parallel to S101 and S102.  However, it's column pin is connected by a copper trace to S83, meaning that its position in the matrix is exactly the same as the right bracket key (S51):  row 7, column 5 in the schematic.  On the PCB, S101.5 and S51 are connected to the same column and row pins on the microcontroller, meaning that any software-defined keybinds will be shared by S101.5 and S51.  I think this is a hardware issue, not a software issue.

If this was the intention when the board was designed, I apologize.  But I think that 101.5 should be routed to column 2 or 3 to allow it to be used as a "space" and S51 to be a right bracket key.

The same issue is occurring with the switch between S90 and S91.  I had to cut two traces and solder jumper wires to get the space and right shift keys working.  You may want to doublecheck all of the extra keys when your PCBs arrive.  I still haven't tested the LEDs, but so far everything else is great!  The USB-C is a nightmare to solder.  I managed to get one working, but I think that I'm going to order breakout boards for the rest of my PCBs.  I'm glad you added a place for a header.

As stated the new revision as an extra key but I've not committed the code yet. I'm working the TOAD right now and will move to the GH80-3000 tomorrow or later today.

The USB-C is a nightmare to solder. 
My approach was flux, solder and than reflew with a hot air station and everything went rather smooth.

Hi @talkingtrees and others :)

I would love to get one of these boards.

a) is there a working one now ?
b) Which link do I follow to get one ?

I would buy 2 working ones with a USB C  header. In Australia.

Thanks for everyone's efforts.

Hi all,

I gave in and tried to order from JLCPCB. I am sure some of my decisions were a little bit iffy. The one I cant get around is the USB C connector. I just added one but they said it was wrong.

Which connector is it from JLCPCB ?

Or do I have to order it and SMD solder it myself. I am scared to do this. :-X. I have had mixed soldering experiences with through-hole let alone never having done SMD.

I have cancelled my order for now and I have to do a re-order. I will get there  :)

You have to do the C connector yourself, I had some trouble with it, definitely a rough intro to SMD (I can replace single diodes easy, but the connector is a pain). Make sure you have some decent flux and solder that likes to melt. I was using flux meant for sweating pipes and "vintage" solder. Killed 3 boards because I was working at too high a temp.

This connector https://lcsc.com/product-detail/USB-Connectors_SHOU-HAN-TYPE-C16PIN_C393939.htm

I bought a lot of extras, so if you're in the US I can send you a couple for much less than a full LCSC order (I'll even throw in some blue or green LEDs).

Looks like JLCPCB recently offer to solder through hole connectors, like USB C.
It may be possible to have a PCB fully assembled by them as of now.
I recently did a PCBA order with them and it went smoothly, only had to solder the JST connector (they did not had the possibility to solder connectors at that time).

The game is to select the right components from their offerings, it request a little bit of work.

I may have a look at the BOM file and see if I can find everything needed, I'll let you know if I have some results.

Had a quick look and could find replacements for most missing components at JLCPCB.
Only thing missing are the WS2812 leds, and the reference of the USB-C connector.

The leds can be purchased separately at LCSC and can be easily soldered by hand.

Soldering the USB-C connector can be a bit tricky without proper equipment (rather fine iron tip, flux, solder wick).

One solution could be to replace it by another reference that JLCPCB has, C165948 (the one use most known designers, used on universal USB C3 daughterboard), but it means a change of footprint and a small rework of the PCB design.
But no to sure @TalkingTree will want to do that.

If you want details on the BOM changes I'd make, I can put here a list of JLCPCB references for the components.
Most are basic parts, with the exception of the MCU that is an extended part.

Hi all,

I used this BOM, this pick and place and this Gerber.

It's nearly there - there is an inventory shortage, however.

It needs someone who has a clue to update the missing item and to probably guide us non-smd solderer types to get it going. or if some kind soul could sort out the bom and pick and place that would be awesome. You would win internet points of gratitude :)

You can replace the out of stock 0.1 uF capacitor by this one that is also a basic part:
CC0805KRX7R9BB104

As for the Atmega32u4 AU unfortunately there is no JLCPCB replacement equivalent :(
If you are brave enought you could still order it at Mouser/Digikey/Other and solder it yourself.

I was just brave enough to maybe do the USB connector. I have managed to stuff up keyboard switches.

Thanks so much though. I feel like we are edging there :)

For this MCU it is like the USB connector but with more pins, so it is doable.
You'll probably screw up one or 2 PCBs the first time you'll try though ;)

There are lots of tutorials on Youtube showing how to solder those beasts with a simple soldering iron.
Having flux on hand is a define plus.

Good luck!

Hello, please help me with the keyboard. I have a g80-3000 without a wire and I need to find out the pinout. Originally there was a ps/2. Thank you in advance.

hi there, i am attaching the rev 2 binaries previously hosted on dropbox (deleted now). unfortunately, it looks like the sources are missing, but it should not been hard to write them from the existing qmk sources.

Which connector is it from JLCPCB ?
This one from LCSC or this one from Aliexpress.

Thank you for starting the project. Is it posible to make this PCB somewhere in Europe ?

Thank you for the files. Can you or anyone else please help me finding replacement components for those indicated "in shortage" or "missing" ? 293834-0

I managed to find the alternative parts for every missing component (at least I think I did) but one is missing : A2541HWV-4P. What alternative can be found for this one from the list ? Can't believe there's none.

Alternatives I found  : 1) for the 22f (column name in the image above) : from unavailableCC4-0805-CG-50V-22pF-J going to change for CC4-0805-CG-100V-22pF-J.A (the difference in V is crucial here ?) ; 2) for 1uF : for unavailable CA45A-A-35V-1UF-K going to change for CA45A-A-16V-1UF-K (the difference in V again - from 35 to 16 - is crucial here ?) ; 3) for USB : missing A2541HWV-4P., no alternative found ; 4) for Reset : from unavailable MAX6346UR46+T to VP809TEUR/T (can't find any difference here) ; for LED : for missing WS2812B-V5 to WS2812B-B/W (can't find any difference here neither).

Can someone confirm or infirm theese alternative components ?
