Hello, I was curious if Anyone was working on any COB processors with arduino? COB just stand chip on board.

This might be better under general discussion unless you have specific questions.
Thank you I will move it there.
COB is usually a custom chip under a blob of black goo.
If you have one, your guess about what it does would be much, much better than a random forum member's.
Hello jremington. I understand. I was curious if anyone was playing around with something using arduino. I was just taking a shot in the dark. I have a upcoming ring project I would love to have any arduino in it to log something.
COB is pretty much beyond the ability of Amateurs to deal with, requiring fancy machines capable of bonding super-fine wires from the PCB to the bare IC die.
These days, there are a lot of chips available that are ALMOST as small as COB, but a lot friendlier to deal with. For instance, an ATtiny1606 is available in a 20pin VQFN package that is 3mm square (with a 0.4mm pin pitch.) This is only "significantly difficult" to deal with.
Get up to the 0.5mm pin pitch (4x4 to 5x5mm), and even us old folks can almost use them!
Hey West, Good to see you. You are right. I was just wondering more curiousity then anything else.It was more of space problem then anything else. Being that the processor I would love to use is way to big to put in a ring type of project. but I get your understanding on it.
