I noticed that the title of my question was edited from

Is there a voltage in pin?


Can I power peripherials from the 5V pins?

IMHO this changes the meaning of the question, but I'd like to ask the community, since I'm not a native English speaker.

My question is about powering the Raspberry via a GPIO pin. The direction of current is into the Raspberry. The new question title for me means: power the Raspberry normally and power the peripherals from the GPIO pin. That would mean the current flow goes out of the Raspberry. That's not what I wanted to know. I did that multiple times already.

  • I'd suggest the motive here was that the original title was very murky on an otherwise good question, although of course the new one was based on a misreading. I've since re-titled it Can I power a Pi through a 5V pin? -- but you are again welcome to roll that back if you find it offensive ;) – goldilocks Jan 11 '18 at 13:58

No, I don't think that edit preserves the meaning. You're asking "Can I power the Pi from the 5V pins?" rather than "Can I power a peripheral from the pins?", which is a different issue. The title doesn't really describe your question accurately any more, so I'd suggest reverting it.

You can roll back any edits you disagree with in the revision history, and it might also be a good idea to edit your post further, as it might be the case that others have misinterpreted your question too.

In addition, if you want to ask the editor in a comment why they made the edit, it's possible to send a comment reply (@user). The autocomplete won't fill in an editor's username, but they will receive your ping in a comment, if you do want to ask why the edit was made and clarify.

    Ok, cool. I did that. Thanks for confirming my interpretation. – Thomas Weller Jan 10 '18 at 15:03
