I know in the past (when the forums had many more participants!) this was a contentious issue with a number of folks not wanting any standard applied. I expect and will want to comment, but any one else that has an opinion is also welcome to chip in. The pins that are over laid have their stroke (except for the 1st occurrence) set to none so they are invisible (leaving the stroke set makes the pin bolder when rendered.) I think this is one of the things that should be standardized, what exactly a schematic in core parts should look like (obviously with external parts schematic can be whatever the poster wants, the only place we really have control is core parts. The power pins are set on top and bottom as recommended by Kicad but are overlaid on one another because if we are going with schematic as an abstract view that is more correct. OK here is a new version of the part with a schematic modified back to the original. See if you would prefer a different schemematic layout.ĭual_VNH2SP30_Motor_Driver.fzpz (11.9 KB) Renumbered the pins with standard boiler plate connectors, copy the descriptions from the original as the original has incorrect svgIds!Īdd buses which are missing in the original part! That results in this test part which has all of these changes. Moved the url from the decription to the fieldĪdded missing silkscreen layerId to the pcb layers. In a number of cases I changed the pins from paths to circles as circles are easier to change (and get a consistant hole size from!) than paths.Īdd version tag set the version to 2 (assuming the original was version 1!)Ĭhange label from MD03A to A (for assembly)Ĭhange family from “motor driver” to “H-bridge motor driver”Ĭhange varant from “variant 2” to “variant MD03A” Mostly more of the same, rescaled, renumbered to start at connector0pin with the numbers rounded to 1/1000 inch. I can have a look at figuring out how to do that if you like.

If we leave the pin numbers as is (starting at 129) we can avoid doing the obsoleting, but as noted I would prefer to renumber the pins.

We could chose to move all the ground pins to the bottom and all the power pins (overlaid to give a single connection point) on the top if that would suit better. I like this because if I am debugging on the actual board the schematic pin is in the same position it physically is on the board which makes it easy to find in schematic. That can be confusing to a new user and I believe is the main reason for using overlaid pins. The downside to this is that Fritzing will not let you make a connection to a ground pin if there is already a connection to the ground net somewhere else in the same net. The overall layout mirrors breadboard (which I find more useful when debugging, but others may not like!) That means there are no pins such as ground overlaid to create one connection.

The pins are renumbered to start at connector0 and the xml numbers are rounded to 1/1000 of an inch.
