Hardware Prototyping With Open-Source Tools

What is Hardware Prototyping with Open-Source Tools?

Hardware prototyping refers to the process of creating a preliminary model or proof-of-concept for a physical device or system. It allows engineers and designers to test functionality, identify design flaws, and refine their ideas before mass production. Open-source tools, on the other hand, are software or hardware resources made freely available to the public, enabling collaboration and innovation without proprietary restrictions. When combined, hardware prototyping with open-source tools empowers professionals to build, test, and iterate designs efficiently while fostering a culture of shared knowledge and creativity.
