Nope. Running a servo from the Pi 5V pin is fine. Please tell me specifically what is unhelpful, misleading, or wrong. Potentially wrong doesn't cut it. It either is, or it isn't.Just because you made it work (with a different model Pi) doesn't make it a good idea. If you read what I wrote, you will find at least one reson why it's harder with a Pi5 -- especially given your other advice that a 3A supply is enough.Well, what if they're just reasonably powerful, or not particularly powerful?
You can, but it's not a good idea, especially if the servos are relatively powerful.
I certainly have had no problems running three servos directly from the Pi 5V output. But... they are 6V devices. And... the GPIO signals are only 3.3V! No matter. It works, and it's fine. Yes, I know how voltage regulators work.
This was before Raspberry Pi messed up the GPIO on the Pi 5. Which I don't own, so I don't know how bad it is.
Ame, I find your posts sometimes accurate and helpful, sometimes amusing but unhelpful, and sometimes (like here) downright unhelpful, misleading, and potentially wrong. We all get it wrong sometimes, but, when you are called out for it, please stop digging.
aBUGSworstnightmare said "Do not try to power your servos and/or motors from the Pi! That will not be possible!". I said "You can drive servos from the 5V pin of the Pi", because you can.
And yes, a 3A supply is enough to run a Pi 5. You will also be able to run a couple of servos with it too!
