So if the USB is connected to the MEGA does that mean the USB is powering it? I'm guessing yes.
I think the mega will choose which supply to use. If there is a supply from jack or ramps it will use that, otherwise it will choose to fed from the usb supply. So yes it will use usb power if only that is available.
Thank you. I wonder if it matters if the USB was direct from the PC or if it would need to be through a powered USB hub? Does one method give more power than the other?
