I'm in need of some solid resources for wiring diagrams and schematics. I often find myself hunting online for basic diagrams or schematics while working on various projects. Most manufacturers keep their detailed information pretty close to the chest. Right now, I'm trying to wire up a new laser module for an engraver, and while I've managed to figure out the wiring for the two lasers (one for sighting and one for engraving), a good diagram with specs could have saved me weeks of trial and error. So, where do you all typically go to find these types of resources? Are there any databases or well-known sites that might even pull information from patents?

You should really check with the manufacturer or seller before buying anything; they often provide this info for free. If they don’t have application details available, I'd be cautious about purchasing from them.

That’s true, but I usually buy from some random Chinese suppliers just to experiment with different parts.
