- QMK compatible
- ALPS and MX compatible
- ESD protection
- Green PCB
- ENIG-RoHS
- Case grounded
- 6 RGB LEDs
- Molex Pico connector between the two boards
- No LEDs for the keys (backlight)
- push button to put the MCU into DFU mode for when flashing really failed. (normal bootloader via ESC key)
- usb-c breakout pcb

Layouts

the caps lock key has two different placements

Someone needs to run the complete keyboard again

Would you be willing to run a plate GB at the same time? Quantity really helps when cutting plates.

Shipping to UE will be 32,5 EUR???

that's including packaging. so express DHL for EU and outside EU it's non-express to keep the price the same. if the shipping price is well below that I will refund some of the price.

Just the PCB for now, unfortunately.

I would definitely be interested in this as my current ca66 has given me nothing but headaches.

MisterKnife · « **Reply #7 on:** Tue, 07 July 2020, 02:17:00 »

Nice, yeah there is quite some interest. I started the GB thread but it's awaiting approval

MisterKnife · « **Reply #8 on:** Wed, 08 July 2020, 03:34:02 »

Cleaned up the routing and ordered a PCB to validate that the added layouts are in the right position. Still waiting for approval for the GB

cijanzen · « **Reply #9 on:** Wed, 08 July 2020, 13:36:35 »

Filled out the form. Sometimes I get double repeated input which I hear is a common issue so having a more stable PCB would be nice. Otherwise I love this board and want to keep it around for a long time!

MisterKnife · « **Reply #11 on:** Tue, 08 September 2020, 03:41:12 »

GB for round 2 will be on the 20th

ever9415 · « **Reply #12 on:** Sun, 13 September 2020, 01:56:45 »

Does it also provide drawing files to PCB buyers?

MisterKnife · « **Reply #13 on:** Mon, 14 September 2020, 02:38:47 »

No it does not

ZyBeR · « **Reply #14 on:** Mon, 14 September 2020, 02:52:10 »

Will there be any change from r1?
I have two of those and would suggest the following improvements:

- Slightly larger switch pin holes
- Raised LED-strip (to avoid light bleeding)
- ISO Support

The R2 will have ISO support and the holes will be slightly so larger.
the LEDs will remain the same.

Sorry the GB isn’t open yet. Awaiting post approval from the moderator. Just keep an eye out

MisterKnife · « **Reply #18 on:** Thu, 01 October 2020, 11:01:33 »

One week to go. This will be the last GB I do for this board.

If we have not hit the total of 30 pcbs in a week I will postpone it by one more week.

cjhard · « **Reply #19 on:** Fri, 02 October 2020, 10:30:08 »

Joined. I never got around to assembling my CA66, but have been thinking about getting around to it lately.

Looking forward to getting around to it with this

EDIT: My head went missing, only just realized I bumped the IC not the GB 😳

Johnee · « **Reply #20 on:** Fri, 26 February 2021, 10:28:38 »

Any chance for a third round?

He says a few post above "This will be the last GB I do for this board. If we have not hit the total of 30 pcbs in a week I will postpone it by one more week."
Sounds like their was not enough interest to warrant one.
I rather have a whole new board, not just the PCB anyway.

MisterKnife · « **Reply #24 on:** Thu, 15 April 2021, 05:48:28 »

If we can get a total of 20 boards as interested then I can do another run. I'll setup another run for an IC. will post the link here

Kerasan · « **Reply #25 on:** Thu, 15 April 2021, 11:25:08 »

I'm in

Corrovich · « **Reply #26 on:** Thu, 27 May 2021, 00:02:17 »

If you are still planning on doing another run, I'd purchase 2.

lakeboredom · « **Reply #27 on:** Thu, 27 May 2021, 04:31:07 »

I'd be in for one

Havattack · « **Reply #28 on:** Thu, 27 May 2021, 13:09:55 »

Are the pcb plans available if someone wanted to get a one off made? Is that even possible? Excuse my ignorance.

ganymede · « **Reply #29 on:** Thu, 27 May 2021, 20:27:27 »

I would happily buy one and pitch some extra $ to support the project in general. My R2 CA66 is a little finicky and I'd love to replace the board and switches. Thanks.

MisterKnife · « **Reply #30 on:** Thu, 10 June 2021, 12:25:57 »

I said I was opening up an IC for this again but I'm holding this as due to chip shortages I am unable to produce them as we speak.

makes sense. Still interested in the next year or so if chip availability ever gets resolved

MisterKnife · « **Reply #32 on:** Thu, 10 June 2021, 14:59:58 »

will keep an eye out on supply

Any updates on this? Anything we can do to help get an order organized? Thanks, sorry to pester.
