Thank you both for replying so quickly!
A part for a 1.8" display is in the Adafruit library… but it’s not the same screen as the one I have.
For future seekers, here’s a direct link: https://github.com/adafruit/Fritzing-Library
Here’s a photo and image showing pin count - as you can see, it’s NOT the same as the Adafruit model:
I will look for a datasheet next…

You change it in the Inspector - bottom right box.
That’s too much searching for me.
Basically we need to know exactly what part it is and if there is a similar FZ part we can modify, and that is too many parts for me to open up and see what they look like.
Post links when you find them.
No luck with pick-n-place. The Speeduino board that gets assembled in mainly THT so probably hand assembled. Looks like we need a pnp viewer.
I don’t know much about ptc fuses and the data I saw in littlefuse’s site isn’t very illuminating, but they mentioned a slow-blow varient which should be what you want if they are really like fuse. A slow blow fuse will take a surge (like your 1.8A inrush) for a little while if the steady state settles reasonably quickly to the 200ma level (or 30ma level if thats whats running in the trace). I’d use something around twice the expected steady state current if it was a fuse. Hopefully someone here is familiar with specifying and using ptcs (as it isn’t me ).

I don’t think you can in Fritzing (and I’m not sure you can in real life either although the PI may be able to be a USB host port and thus may work). In the fritzing case there are no connectors on the USB ports in either part. I suppose you could put an unconnected wire between the two ports or you (or one of us) could modify the parts to add a connector to the usb port. In general wanting to show a U?SB cable in Fritzing is a rare requirement so typically parts don’t have connectors on the USB ports.

Welcome to the fritzing forum!
We hope you enjoy it, if you have question related to the software, feel free to ask 
Looking at it, seems good enough I can add the branding stuff and also some extra features.
What is the first logo? I can’t find it. I got already mediatek labs and linkit.
EDIT: Nevermind, found the logo inside seed_arch_breadboard file.
Thanks! This is a really fun board and I appreciate your help making a part for it!
As a contribution here is Old_Grey’s svg rescaled and with the lipo battery and grove connectors added. The pins need to be renumbered starting from zero and the other two views added. Easiest to do that by parts edit a 48 pin generic Ic then swap Old_Grey’s svg and then modify the schematic and pcb svgs (which will have the correct pins defined) either by hand or via parts editor which ever works for you. Note the names on the pins are incorrect as well. As usual rename the fzpz to .svg to get the svg.

EDIT: I fixed the image size. (Sublime)
Where it is? I just added the logos already to the Old_Grey’s svg.
Also I will add those logos here as .AI files to save us time. Due to Seedstudio using a premium font (Riona Sans I think) for their branding logos, I had to remake them based on vectorized png. The result is very close to the original font.

My bad, didn’t check the upload. I think the svg is actually that little blip if you right click and save as svg (I forgot to rename the file it looks like). In any case here is a
copy with the fzpz extension.

Can’t open it, getting an error message Failed to load: open.zip()
Happens to me as well. The original is fine, so it was the upload somehow. The forum seems to be detecting this is Old_Grey’s file and substituting it in place of mine. This one LinkIt One_mod.fzz is really zipped so you will need to unzip it which should give you the svg.

I don’t know what is going on but all I could download was Van’s 1st small green dot. All the rest open with an error.
Now that I know how to modify paths, tell me and I will extend the UNO PCB view in that same way for the LinkIt PCB view.
I’m not sure about PTC fuses either but I think they trip when hot and reset when cold.
I ordered some Ebay 0.56A, 0.9A, and 1.1A a couple of day ago, but I was thinking maybe they are too high. I think I will go with 200ma because I don’t want this thing dying just as you pull out into a line of heavy traffic.
I can not say I know a lot either but I would like to add you want a PPTC not a PTC thermistor as one is a fuse and the other is just a temperature dependent variable resistor. At room temperature the PPTC will has a resistance of x and will quickly increase as current causes it to heat up at which point it will reach a resistance high enough to effectively shut down the circuit similar to the way a fuse does. On the other hand a normal PTC will not reach a point where the resistance is high enough to shut off the circuit quick enough to protect the circuit.
With all that said I have recently been working on a circuit with a few Farad of super capacitors being charged by a LiPo cell where I needed to deal with Inrush current and my research lead me to NTC power thermistors like 16D-9 which limits the inrush current but overtime allows higher currents if a constant demand exists. I think this may be a better option for you since it only sounds like an inrush current issue rather than a constant current issue.
