There is a free open source program called freecad that allows for 3D modelling of mechanical stuff and this program exports and imports idf files. A quick google seems to show that importing and exporting of idf files is possible. I think the program does have all these features. The Gerber files are files that you can send to a pcb manufacturer to produce actual physical pcb. But also of the mechanical housing for the pcb to be designed. This eases the physical design of the pcb. With IDF and DXF files, you can export and import mechanical drawings. The interesting things will be how it supports the different formats in gerber files and idf files and dxf files. I had a quick glance and it seems to have features only found in professional software such as trace length matching and a 3D view of the pcb design to see how the design will end up and if it will fit. That program looks very nice and interesting. Especially for starters new to the electronic world. But for home hobby use, Fritzing seems nice. I think KIcad is meant to be used for serious pcb design. It is available for windows 32bit and 64bit. But for some relatively complex home projects it could be fine.Īfter decompressing the file, it is about 189MB in size. I do not think you can do real complex stuff with it. They also support arduino boards and a lot of sparkfun components and have a growing library. Meaning it has a schematic mode where you can insert components and draw wires in a neat fashion. It also support prototyping on a breadboard. If you are an electronic hobbyist and you want to make a schematic and a pcb but do not have the money for a real program. If you have not heard of it or read about it before : Fritzing. The previous renter must have been deaf or something. As it turned out, there was inside my intercom a potentiometer to lower the doorbell volume. In my search for some documentation, i came upon a German website that had some nice project about automating a similar door intercom and used this interesting software. I was looking for a way to turn down the annoying loud volume of the door bell from my door intercom in my apartment.
