SvgRenumberConnectors.py renumbers connectors in an svg. I have some tools (some published on github some not) that will create fzp boilerplate for connectors, (FritzingCreateFzpConnectors.py on gighub) and these 3 which need more work before they are ready for prime time 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…ĭescribe what I do. 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. 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.

Part creation howto part 1 breadboard and pcb Tutorials - Guides - How to's - & Experiences. I won’t use Fritzing to create PCB’s (I use KiCAD) so I followed your recomendations there, although it doesn’t make any sense to me to use the PCB footprints for this two parts, especially the driver itself, as it is a module with THT components that won’t fit in a PCB (but I’m no expert in these matters ) What I saw instead is that you changed the JST connector pins from 2.50mm to 2.54mm(0.1in), that was not a problem anyway. In the motor the holes were slightly to large so I set them to the standard 0.038in for header pins. It was unnatural so I swapped the pins genre in the JST-connectors for both the motor and the driver and it’s easier now (again, traded accuracy for usability).

The spacing was not perfect (now it is as I sacrificed/traded accuracy for usability), but it appears that Fritzing assumes female pins to be in the bottom (because of the breadboard?) and male pins on top when you drag some part into another (to connect), so the weird effect result is that you had to connect the driver board to the motor, and not the other way around.

My original part worked fine: it was NOT a problem of alignment (did you try the attached FZZ file?) but, as you mentioned, a question of pins genre. I moved the connectors in breadboard slightly so they all align and now that works Unfortunately the current breadboard doesn’t align on 0.1in boundaries so that doesn’t work. I assume because the stepper has female pins you were hoping to be able to connect the stepper to the module in breadboard and have it connect.
