The USB Switch Buddy was made to solve a simple problem: Connecting to a USB device without also powering it off the USB host.

Originally this came about with one of our 3D printers where the main control board would receive power from the Raspberry Pi running OctoPrint. The original solution was some mild surgery on a spare USB cable. But there are plenty of other situations we run into on a regular basis where this has become a problem. For example, many of our LED displays require far more power than USB can deliver, so power is provided to the micro-controller separate from the USB connection. With the USB Switch Buddy that's no longer a problem.

We considered not including a switch at all. But decided that it could come in handy, allowing you to power cycle a USB device without fully unplugging the cable. To top it all off, there's a 4-pin 0.1" header allowing you to monitor the USB line voltage and even the data lines, should you need to.

This is a simple kit that even the most novice maker can assemble in a few minutes. See the instructions linked below.

It soldered right up and did the thing!

Found this handy for preventing a Smoothieboard from being powered over USB. Off means off! Used heat shrink tubing for a case. It would be cool to have a real enclosure as well as a version that goes on the other end of the USB cable.
