Multipurpose USB Fuse

[badboy]

So this is my first Kickstarter project. My hope is you guys actually think it's a good gadget. Let's see.  Maybe i'll get some more backers or at least som constructive ideas

The board should be less wide and use components on both sides to achieve this. This would block slots of a USB hub.
I'd like to see ESD protection at least on those data lines

Looks neat, but it looks like it only has one PFET style device and so no way to block backpowering (when the slave tries to power the host, for example connecting a Raspberry Pi to a power supply and to a computer via USB.) It would only require a change to a dual PFET device with the devices back-to-back and the gates tied together to implement this function.

I did initially for chargers, thats why it's so "big" but yes it would benefit a smaller size.

Actually there is protection diodearray from Wurth on all lines.

Nope you are right. No backpower protection at the moment. Good comment.

If you run the traces down one edge of the board, You should be able to fit the components on both sides of the PCB, and have it little more than the width of the USB socket.
Not going to be as easy to assemble though. I'd put the larger SMD packages on the underside, as far less likely to break/fall off.

Also minor mistake on your KS page, here is the fixed sentence.
"The fuse shall work independently and use settings set by user and not by some software control"

:-)  great thanks
