Yes, I thought ptototype-ish. "Prototype" means something different when you're mass producing.
Like an intentional color variation to quickly-visibly track the results, and keep-go back to the old color once results are proven.
That's what I remember we used to, but I could never tell the difference in color. I always went by part number.

If they own the PCB process, then they will be tweaking their process as production runs. Process is always getting tweaked with supplier chain changes. Prototypes lots are usually only 10 or so at a time. Those never ship to customers - beta's may be some - and never leave the lab unless it's via the scrap bucket.

But again, any of my color based rhetoric is probably suspect LOL!

A new version of the 112 VCO has landed. Complete with temp co resistors - these are the slightly bigger resistors (0805 size) near the larger chip in the middle of the board. Basically a surface mount version of my modification. You're welcome Uli.

The new board is the green one. So don't buy orange ones unless you don't mind scale drift or fancy doing a tricky modification.

This was my photo. The actual colour of the PCB of the new revision may not be green (it may or may not be green) - however it will have REV C (or greater) stamped on there. So ensure your module is a REV C or newer.

Also - I used to have a muffwiggler login, and it didn't work (google passwords remembered it) - so not sure but re-registered today. So I guess I'll just look like a newb again ;)
Cheers,
Ranzee

Have we got a change in exterior packing? I don't see a clear revision on the boxes.

I just discovered this from your post on GS. I originally got it from another interested party who had found it on Facebook. I hope it was OK to post it on here.

Good to know.

The question is, are those of us with earlier drifty versions going to get replacements?
