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.

Post by: PlsCrit on Mon, 06 July 2020, 19:41:28: I would definitely be interested in this as my current ca66 has given me nothing but headaches.

Post by: MisterKnife 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

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

Post by: cijanzen 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!

Post by: ZyBeR 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.

Post by: MisterKnife 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.

Post by: cjhard 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 😳 :-X

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.

Post by: Havattack 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.
Title: Re: [IC] CA66 replacement PCB R2 now live
Post by: ganymede 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.

Post by: MisterKnife 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
