Hi
Where can I found datasheet of this Scale PCB? Information like codes to configuration of it, Reading / dumping micro data,...

ALL of that information should be available in the manufacturer's application data. But if he manufacturer does not want to be known, then in the IC maker's application literature.

Helps when it is the same photo of the exact same board
Well, that's the beauty of many Chinese boards – often they are sold by many companies and some of them have more details. This can lead to a schematic pretty quickly at times.

I guess an alternative to a quick search is lecturing that getting stuff from China is a waste of time and you won't be able to find documentation and it will be wrong if you do. Too many answers here (in my not-so-humble opinion) are scolding interrogations with a thinly veiled "how can you be so stupid". If people knew the answers, they wouldn't be asking the questions, and if the questions don't make sense, some explanation may go a long way. [/stepping off soapbox]

That was the very first thing I noticed too. EDITED OUT.

Last week I scrapped a sandwich build cooler that was a made in China product, because the service guy could not get any repair parts. I don't service freon systems because I do not have the license or the tools. I did start up the replacement and it was clearly a better product.
For the circuit board shown in post #1, I seldom search for the information. And never with a phone.

Hi,
I personally consider discussing and decrying a fellow member's integrity, who joined AAC in 2021, out of order.

He has raised many more than three threads, and he has made 44 posts

I would suggest that if you suspect someone acting in a questionable manner, you raise a Report to Moderation.

It was just an observation that, by whatever coincidence, the photo that the TS used happened to be the same photo used by the site the quick search found. I'm not sure how you come to the conclusion that it was somehow a scolding interrogation. If there was any thinly veiled meaning at all, it would be related to how successful the search would have been had the TS posted a picture of their board taken with a phone from a completely different angle in completely different lighting conditions with a completely different background. The curiosity was purely on the capabilities of the image search algorithms used by the search engine.

With CircleSearch (you circle an image on the screen and it instantly searches), you still have to use some judgement. Some of the results are completely wrong, but in this case it did find the exact picture, along with some very similar appearing scale boards, quite possibly using the same chip based on the surrounding components. From this information it should be pretty easy to drill down and find the needed info.
