In electronic engineering, open source PCB design is becoming an important way to promote technological innovation and lower the threshold of development.
1. What is open source PCB design?
Open source PCB design refers to making all the files of the circuit board design (including schematics, PCB layouts, Gerber files, BOM, 3D models, etc.) public in the form of open source license agreements (such as CERN-OHL, MIT, GPL, etc.), allowing other developers and teams to freely use, modify, copy, and even use them for commercial purposes.
This is similar to open source software, emphasizing the spirit of openness, collaboration and sharing, which not only helps developers reduce repetitive work, but also promotes the standardization and innovation of electronic design.

2. Tools for open source PCB
If you want to participate in or create an open source PCB project, it is crucial to choose the right design tools and sharing platforms:
Design tools
KiCad: KiCAD is a free open source PCB design software for circuit board designers and students. It provides functions such as schematic design, layout design, automatic wiring, 3D model design, and supports multiple file formats
EasyEDA: Based on the web page, it is suitable for beginners to get started and supports direct ordering and board making;
Altium Designer: Altium Designer is a professional electronic design automation (EDA) software that provides electronic engineers with a complete solution for designing printed circuit boards (PCBs) and electronic systems. The software integrates functions such as schematic design, PCB layout, signal integrity analysis, and generation of manufacturing files.
Eagle: Can be used for non-commercial open source projects and supports a large number of plug-ins

3. Challenges of open source PCB design
The integration of open source design faces several challenges, such as more noise problems. When the circuit board uses high-current switches, the noise will scatter into other lines. But the biggest and most important challenge facing open source design may be the change in the learning curve. For example, although engineers can easily copy and paste open source layouts, they may also lose the opportunity to learn the basics of complete design, including setting spacing, necessary line width, impedance matching, etc. This undoubtedly puts engineers in a dilemma: if they do not use open source design, they will encounter certain component design problems in the design process, and if they use open source design, they may not be able to learn in-depth design knowledge. If engineers do not understand the basic principles of design, they will find it difficult to cope with the unique design challenges in the future. On the other hand, using open source design can provide engineers with a new perspective on the PCB design process. In other words, if the method is appropriate, the learning barriers caused by using open source design can be transformed into a real learning opportunity.
Open source PCB design is not only about technology sharing, but also about the dissemination of ideas. It breaks down knowledge barriers, lowers the threshold for innovation, and shapes a more open, collaborative and inclusive engineering culture. In the future, as the open source hardware ecosystem continues to mature, open source PCB will play an increasingly important role in education, business, scientific research and even consumer electronics. Whether you are an electronic engineer, maker, student, or hardware startup, participating in open source PCB design projects will be a rewarding journey.
