This is a basically a pass through device for USB Type A connectors that doesn't connect the 5V line. it has a Male connector and one end and a Female connector at the other.
Well basically it is simple, non-intrusive way of solving a problem that 3D-printers connected to Octoprint machines have, their screen stays on, even when their PSU is off because they are still receiving 5V via USB.
Plug the Power BLough-R directly into a USB port of the computer running Octoprint and plug the printer's USB cable into the Power BLough-R. Your Octoprint machine will be able to communicate with your printer as normal once your printer's PSU is on.
This has been a little bug bear of mine for a while and wanted to come up with a simple solution for it. Up to this I was plugging out the USB cable every time I turned off my printer.
I also wanted to make a PCB and this is my first ever one, as you might be able to tell. It's certainly not the most complicated device, but it achieves what I set out to do!
There are other solutions to this problem, some people have taken to cutting traces on boards, others have modified the USB cable (either by cutting the 5V line or placing tape over the connector), but I thought this would be a nice, non intrusive way to achieve the goal.
One of the people who bought a Power BLough-R created a case for it and it's awesome! It's a press fit case and it works perfectly. Please leave a rcolbert a message or a like on thingiverse for doing a fantastic job.
Easy, all through hole. Once you place the USB headers on top of the PCB (as shown in the picture) you really can't go wrong!

Hey everyone! My name is Brian and thanks for checking my Tindie Store.
I'm a software developer by trade but I've recently gotten into Arduino development after discovering the ESP8266, a WiFi enabled Arduino chip for $5 delivered blew my mind!
I started looking at Arduino stuff late 2016 and I'm really enjoying it. I did Electronic and Computer Engineering in college so I had some base knowledge of electronics but I'm having fun learning it again.
