Ever have a time where you need to only pass data over a USB cable and don't want to hack up the cable in order to block the 5V power? Or do you have a Creality printer that leeches power from your Raspberry Pi when you shut the printer off?
This USB dongle is a direct passthrough of data, but the 5V pin is disconnected. So simple, so useful.
Great for Octoprint/Octopi users!
