XR2206 kit - schematic/mods for improvement - offline?
« on: September 18, 2020, 10:51:57 pm »
A very nice man made a video showing improvements to the notorious and cheap "XR2206" (likely fake IC) kits, but his schematic files seem to have vanished!

His name was Roger or something, from "Kainka Labs" - does anyone possess his modified schematics? I have a kit here and want to built it using his mods at build time.

By the way:

~ Yes, I know there are other options available, re kits etc.
~ No, I don't want them - I am simply asking for the above info, or related, if you have it.

Here's his video:



Cheers

In the description there is a link to "schematics with the optimized components and instructions".

Unfortunately the link resulted in "File not found" for me, but it seems Kainka labs intended to make the information public. So, perhaps get in touch with them: https://www.kainkalabs.com/  and also https://www.kainkalabs.com/upload/index.php .

Also check in the video around 21:13 for a screenshot of the schematics and list of changes.

I've decided to also get myself an AD9833 module, as I hear great things about them, and WOW are they affordable! Any thoughts on those? Much appreciated. :))

The AD9833 has been discussed quite a bit on these forums.

In particular, check out this somewhat recent thread:
