An Open Platform for Easily Reusable Subcircuits
KiCAD when making hierarchical sheets creates a new.sch file for each sheet. One way solve the problem is to make several sheets and then copy the original sheet's.sch file and have the copies replace the.sch files of other sheets. This way, when entered, each of the copies will look like original sheet. PCB Layout Make professional PCB layouts with up to 32 copper layers. KiCad now has a push and shove router which is capable of routing differential pairs and interactively tuning trace lengths. Dec 09, 2016 F.Paste and B.Paste is where. If you save and drag the.kicadpcb file onto the OSHPark web page you'll get a pretty purple PCB in a week or two. That's not to say this PCB actually works. Panelize.py is a tool I created a long time ago to panelize one of my kicad PCBs. Version 3 is a complete rewrite which supports kicad format 4 and 5 PCB files, those with the ending '.kicadpcb'. It can copy and optionally rotate and flip parts of PCB files. It can also be used to merge multiple PCB files. KiCAD PCB Tutorial. There are many PCB CAD tools. Some examples include: Altium, Allegro, PADS, Eagle, Diptrace and KiCAD. The principles behind PCB CAD tools are generally similar. Each tool has its own design choices, with these come advantages and disadvantages. Once you learn your first PCB CAD tool learning more should not be as difficult.
In software, one thing we all take for granted are libraries, enabling reusable software modules, bundling functionality together, and avoiding reimplementing the wheel over and over again.
In electronics, we have integrated circuits, so we don't have to build everything with just discrete components. This enables more complex functionality in smaller size, reduces the complexity designers need to handle, and enables people to create more.
Thanks to easily accessible development boards, like Arduino or Adafruit Feather, building prototypes got a lot easier. However, when we want to leave the wire spaghetti behind, and put every module neatly on a single PCB, we hit a wall.
Electronics hardware development is not only fragmented between multitudes of EDA tools. Reusing a design, or composing a project of multiple designs, is still next to impossible in 2020. Not even the elsewhere so ubiquitous (and sometimes carelessly done) copy-paste tricks work; having to juggle a PCB layout and a logical schematic simultaneously presents an inpenetrable barrier to most development tools.
My own journey into electronics only started two years ago. I have been using computers for ages, and was fascinated by what's below the cover. I am a self-taught electronics tinkerer, who is intimately familiar with software development tools and practices, and peeking into the world of hardware development got me amazed.
After the initial rush and fascination wears off a bit, and building electronics becomes more mundane and part of my daily life, I started to wonder: why do I have to build some parts over and over again? Where's my go get
or pip install
for that DC/DC converter I need? And why can't I even reuse my own schematics, and copy-paste between KiCad instances?
At least the last part will come whenever KiCad 6 gets released (and is already available in the nightly builds). But the other issue still stands: how can we share subcircuits we built? Trying to collaborate with other people on open hardware projects showed us how impossible it is today.
Often it takes many hours of consideration and consulting datasheets, reading application notes and dead-tree text books to get something right. Then meticulously adjusting the traces to get the best performance out of a layout, or to squeeze everything into the smallest area possible. Something I will need to do again, even when using the very same parts in the next project! Why can't I easily share the fruits of this work with others? To achieve more with less work, we need to stand on the shoulders of giants, like we do in software today. We can often just include a library, call an init function with the right parameters and get on with it. Read the documentation so we understand what we must know, but we don't always need to learn how exactly it works. So why not here too?
There is a growing Open Hardware movement, a diverse bunch of people with intimidating skill levels, and they are reimplementing the wheel over and over. What if it were easy to share those tricks, to reuse what we already made, tested, so we can build better, cheaper, or achieve more? What if we could drop a known good layout into a design? And maybe even dynamically parametrise components, so that we don't have to calculate everything by hand or by obscure spreadsheets?
This is what inspired the EDeA project. Out of a very naïve 'how hard can this be?' question, we first built a primitive prototype tool to merge KiCad projects, including their schematics and PCB layout. This still need a lot of work before it can be considered safe, including correct net aliasing, nesting of subschematics, etc. But this solves only one part of the problem, something which should be solved in the upcoming major release of KiCad anyways.
We are now laying the groundwork for EDeA; a community portal to share, find, and assemble subcircuits into KiCad projects. It's all in rough shape, and we're still a bit away from the first alpha we will show to the public, but we're getting there.
What we envisioned is an easy-to-use catalog of various circuit submodules; power supplies, data converters, microcontrollers, processors, and so on. These submodules contain schematics and a PCB layout, among with useful metadata; number of copper layers, component count, surface area, necessary manufacturing capabilities, and so on. Each of the subcircuit category should also have meaningful parameters; for example efficiency for a power supply, bandwidth for a transceiver. You can select any amount of these submodules, click a button, and get a KiCad project which contains all the submodules as hierarchical subsheets. Now you only need to wire these together as you need them, and in pcbnew move the already layouted submodules to fit the exact shape you need. To keep the already complex project manageable, we can't go into auto-connecting and auto-placing of submodules. At least not yet.
So stay tuned while we finish the boilerplate and the back-end, and we will get back to you! We count on your feedback and your help on filling the repository with invaluable circuits.

Our work on EDeA is being funded by the NLnet Foundation (project link) so that we can work on the project full-time during the next months. This also means that significant effort will be put into it being accessible and we're committed to respecting your privacy. We're interested in open collaboration and not user metadata. EDeA will also always be completely Open Source and free for everyone to host themselves if they choose to do so.

Kicad Pcb Design Tutorial Pdf
We're building an open-source web portal for sharing KiCad subcircuits, which will enable you to create more by doing less.
I kind of asked this before but I don't think I phrased it clearly, so I ask again...
If I have a circuit block, that is repeated many times in a design, what is the easiest way to create this in the PCB layout?
Do I need to piece together each individual block, or is there a way to copy and paste the block?
thank you
