Had to cover it in a random mix of caps until Laser and Taro arrive, but this board is gorgeous!

Here is how mine ended up:

You guys rock.
Kindly appreciate for those pics.

ohh! one more helpful build tip if u want forever backlit LEDs...when looking at the pcb switch side up, all the LED positive side was on the right...at least for hhkb layout with split spacebar. i did not try the winkeyless or full size spacebar. hope this helps.

There are signs for every led pin hole, like this:

And those on CA66 PCB are inverted mostly.

How did you manage to flash it using qmk?

You can compile a hex file with QMK. Please check our guide in the main post.

How did you manage to flash it using qmk?

For me, I cloned the QMK repo, made my preferred layout, then compiled the .hex file myself using the Ubuntu terminal from the Windows Store. The only thing that seems different from this is that this board uses a different bootloader as opposed to all the other QMK boards, so you can't flash it using QMK toolbox. You have to use the reflash tool from ydkb.io.

You could also generate a QMK .hex from the online QMK configurator and use that too.

Does anyone know a way to change the bootloader so we can use QMK toolbox? I'm just assuming we can't from what others here have said.

[ptiede]

Oh ok I misunderstood I thought you found a way to flash it using qmk toolbox. I think there really isn't any way to flash it without using the ydkb flash tool.

[jlboi69]

Yeah. I wonder if it's possible to ISP flash the default QMK stuff onto the microcontroller?

Theoretically you can flash the DFU bootloader onto anything. In reality, without knowing how they've wired reset and hwboot, you run the risk of having a board that can only reliabily jump to bootloader via soft reset, which is never ideal.

I can confirm the board works flawlessly with DFU bootloader, I've already reflashed mine and it is working correctly.

For people considering change their bootloader to DFU bootloader and be able to flash via QMK toolbox, here is some information.

The board uses the BootloadHID bootloader, and can be flashed via BootloadHID. (And of course the YDKB's reflash tool, which is actually a wrapper of BootloadHID and dfu-programmer ... etc.)
 (https://github.com/whiteneon/bootloadHID/blob/master/commandline/bootloadHID.exe)

I believe it won't be hard to make QMK toolbox support BootloadHID bootloader since both the binary and source code of bootloadHID.exe are available. The QMK toolbox will need to be modified to recognize devices using BootloadHID in bootloader mode. (VID: 16C0, PID: 05DF)

To change the bootloader to Atmel DFU bootloader, you'll need to use an ISP flasher to ISP flash the DFU bootloader.(https://github.com/qmk/qmk_firmware/blob/master/util/bootloader_atmega32u4_1_0_0.hex)
Also, you will need to change the high fuse setting to 0x99 to make the board functions correctly with DFU bootloader. (IMPORTANT)

That's a way we were expecting to see when using CA66. ;D

Great job OP!

[Bael_Zharon]

Any Silvers out there looking to swap for a Black? I just got my hands on the black one and might want the silver over it.

[wjchen]

Thanks for posting this info! I'm considering trying this with my spare pcb.  I would not have not have known about changing the high fuse setting so that specific info is super helpful.

No problem, I myself stuck for a bit until I realized the size (and some behaviors) of these two bootloaders are different. Therefore, different BOOTSZ1, BOOTSZ0, and BOOTRST fuse bits are required.
Be sure not to mess with other fuse settings (especially LOCKBIT) though.

Thanks for helping my mate. So detail!

Happy to help. 




For people without access to the hardware required for ISP flashing but still would like to use QMK toolbox for firmware flashing, I've modified the QMK toolbox to be compatible with devices using bootloadHID.
My fork of the QMK toolbox can be found here. (https://github.com/wjchen-vlsi/qmk_toolbox)
I would suggest you wait for jackhumbert to review my changes and hopefully merge my pull request into the upstream branch (and a official release).
If you absolutely can't wait, here is the compiled QMK toolbox executable that supports bootloadHID. (https://drive.google.com/open?id=1WMQJStONnROpGvzD4XitX0RXJuPk3s7u)

When you say wait for him to review and so on, are you talking about the guy managing the qmk toolbox? So like it will be a part of the software at some point?

Really happy with the way the brass plate and titanium badge match each other. Pic doesn't do the keyboard justice. It's an incredibly beautiful piece of metal.

Now to wait for those incoming vintage blacks and vintage linear greys, save up for DSA Granite and learn how to solder properly. Possibly also look into a custom titanium badge. By the way, is that CAD file released publicly yet? It was mentioned earlier in the thread.

It's a slow process, but I'm in it for the long haul.

Did you put your board into bootloader mode first? (Plug in the cable while pressing the ESC should do the trick)
If your board is indeed in bootloader mode and reopening the toolbox still doesnt work for you, would you mind looking up the vendor ID and product ID of the board (in bootloader mode) for me?

Excellent! Custom badges is like a "hidden" feature of this board. I think it'll be really interesting to see where that leads and what people in the community will come up with.

Any further news about a possibility for a CAD66 PCB GB? Perhaps too soon to say. Just wondering because individually controlled LEDs.

[BobCarltheThird]

Hey guys, I decided to test my PCB before soldering it and was wondering what the top two keys on the right of the LEDs do on the stock keymap. The one on the very top seems to mess with the LEDs and the one below it doesn't seem to do anything. Also I think the third LED down is dead as well. Any advice would be appreciated.

Try to flash it with your own hex to test it. Those two keys are both for RGB animations.
That's a WS2812b RGB led. It would be great if you can find some near your place to replace it.

Photo attached - I could not focus it any better, but it should be visible. It's the black one on the right. Should I try aligning it manually and soldering its left leg?

[Jubileus]

Yeah you should. Its not too hard. It looks like its not making contact to the solder point

[Jedi]

I just finished building mine, unfortunately left arrow key doesn't work  I see the black element near that key is misaligned. How can I fix this?

I looked at your pic and this would be a very easy fix. Grab a hold of the resistor with your tweezers and apply light pressure with your soldering gun to each side to remove the resistor. The solder comes off just like tape. Then make sure to clean up either sides excess solder to prevent bleed over from the two contact points. Reset the resistor between the two contacts and tap the soldering tip to the first side to wet it to the pcb and then the second side. Please be careful not to ever touch the tip to the black resistor itself, only to the contact points.

The work is very forgiving otherwise as you may need to repeat the step to get it right.

Oh and please be sure to observe polarity so make sure it is seated with the writing in the same direction as all the other resistors.

So, my CA66 is having a strange issue. I was using it with my work Macbook Pro, and it was fine for hours, but then I woke the laptop from sleep mode. The LEDs turned white, and the keyboard is no longer working. I unplugged and replugged it, which didn't work. I have tried reflashing it but it will not enter bootloader mode. The LEDs come on but are solid white. Anyone have any ideas on how to fix it?

In the heat of the battle I initially soldered a resistor at neighboring switch Those parts are small compared to switches so it took me a while, but now my left arrow key works perfectly.

My thoughts on the keyboard:

• It's brown in low light and burgundy in bright light. If the whole case was the color of the back plate I would be happy, but as it is it's a bit too browny for me
• It's really fast for typing and I really enjoy the bottom edge which is enough for my thumbs to rest (which is the way I'm used to put them)
• I like the configurator, but I would really love to be able to do everything in Linux, so I might try the solution for alternate bootloader soon
• The texture is not as smooth as my other anodized keyboards, which makes for more classy look, but becomes dirty very quickly
• The case doesn't sit entirely flush on the desk, I had to add a small rubber feet at one side
• This is the first keyboard I am completely sure I need to mod with silencing foam, because there is a lot of echo and ping - given I use Zilents and properly lubed stabilizers for the first time it would be a shame to not keep it really silent.
• The cable I used initially (which comes from my phone) worked fine, but when I started using dedicated one I have to apply significant force to remove it
• The case is high profile, but some of the caps of my MT3 /dev/tty set are tiny bit above the case
• My case has some minor imperfections on the inner side of the bottom plate (which I don't care about)

This may sound like some bashing, but in fact this keyboard comes very close to my mythical "end game"  The good stuff, like perfect layout, nice bottom space, low height and QMK support I knew from the start, so while I would love to receive perfect product I am happy what I got is close enough and with some mods I should be able to make it the best keyboard I have.

Also props to GB runner for quick responses and basically on time delivery - reading through some other threads it's really not that common these days. Btw. my package was picked up at 1am in HK and arrived to my office in Poland the next day at 3pm, which I find amazing. That's probably the magic of express delivery

BootloadHID is available for Linux

[wjchen]

• The case doesn't sit entirely flush on the desk, I had to add a small rubber feet at one side

Probably due to the rubber stripes come with the board not all the way in the slots (i.e. air bubbles between the case and the double-sided bonding tape), try to apply forces along rubber stripes (to squeeze the air bubbles out) and see if that helps.

Sounds exactly like an issue myself and some other QMK users are experiencing (with an M65-A). There was a closed issue on GitHub that I recently posted on and resurrected - please read through this and follow these instructions. I think it will help. And ignore the "boot magic" stuff, it seems to just be an issue when going in/out of sleep mode with RGB on.
