sch schematic file which represents the electrical schematic and all the connections.
brd file which represents the physical layout of the board, but there is also. Basically you can unzip the files into EagleCAD's project folder, go to EagleCAD, and try opening the. ZIP file let us know, we can work on next steps to open the project for the first time. Once you get Eagle installed and download the. You can download EagleCAD at the official website You can export EagleCAD format to other CAD packages, but that is well beyond the scope for a beginner. Stack Exchange/Overflow will not answer any questions like "which CAD package is best", but in this case since Arduino is offering the files in EagleCAD format, I would suggest you start out with EagleCAD. ZIP" link to download the "Sort of" open-source hardware files. Surf to the official Arduino website, go to this page and scroll down and click on the "Eagle Files in. You just can't commercially sell them without getting licensed by Arduino company. Provided that you respect their brand name and don't try to re-sell their items without proper licensing, you are allowed to copy and produce as many Arduino UNO's for personal use as you want. The Arduino is quasi-open source hardware.
Starting with the Arduino UNO is not a bad idea. More often than not the output from CAD programs is not "manufacturer read" and will require some post-design tweaking by the PCB manufacturer. Almost always, the PCB manufacturer will take your design and then want to make further changes to make your design "manufacturable". Part of the learning process of designing PCB's isn't just getting the design correct on paper, but learning how to work with the PCB manufacturer after your design is finished. PCB design is almost a "Trade skill" - sometimes more art than science, so to speak - it will take you some time to build your skill, but it's well worth it.īeginning by producing existing designs is a good idea.
