Help on creating pololu motor shield drv8833

[fritzing-samuel]

Hi,

I’m trying to create this as fritzing part.

Unfortunately I’m not able to select the right graphics for the connectors 9-16 in the pcb-view.

I already checked the svg xml and hope I did everything right there.

A pointer on what I’m missing would be super helpful.
Thank you!

The .fzp file is only one part of the part, you need to upload the .fzpz file for the part before anyone could do anything for you…

edit: There is also already a part available here:

Hi Peter,
thanks for your reply. I will attach the correct file now.
Unfortunately the schematics and the PCB of the DRV8834 don’t fit perfect.

Maybe the part you linked to, would have been a better starting point…

OK here is a corrected part, you have a lot of things wrong. You started out from an incorrect part, it had schematic subparts (thus no schematic as yours is not properly configured.) I replaced schematic with one generated by the Inkscape extension as being easiest. The connectors should start at 0 not 1, so I corrected that. In pcb the holes were 0.035in (for an IC) rather than 0.038in for a 0.1in header. Corrected that. Ran the part through FritzingCheckPart.py to fix up the font size problems. All these things can be found in this tutorial on part making:

Part creation howto part 1 breadboard and pcb

Someone in this forum post requested help to fix up a part. So while doing that I decided to record what I needed to do in order to fix the part to provide a tutorial to create new / fix broken parts. If you start from the Tarjeta S4A EDU.fzpz file posted in the above thread, you should be able to recreate my improved part posted in the same thread. I started by loading the original part in to Fritzing, that indicates breadboard is (at first look anyway) pretty good, but schematic and pcb are…

Fritzing-Schematic an Inkscape extension - released

Hi all! I have been working on an extension for Inkscape to create rectangular schematic symbol .svg files for use in Fritzing. I think I created a useful tool to speed up creation of schematic symbols, and now I want to share it with the community. It’s available on github: https://github.com/revolt-randy/Fritzing-Schematic-an-Inkscape-Extension. To install: In Inkscape, the edit menu → user preferences → system will have an option for ‘User extensions’ - allowing you to open the folder to…

Hi Peter,

thanks again for your help.
I see it is not a good idea to start from an incorrect part.

Thank you very much for helping me out!
