Open Source Hardware refers to physical devices and systems whose design and specifications are publicly available for anyone to use, modify, and distribute. This concept promotes collaboration and innovation, allowing individuals and organizations to build upon existing designs without legal restrictions. Examples include Arduino boards and Raspberry Pi computers, which are widely used in educational and hobbyist projects. The open-source approach encourages a community-driven development model, where users can share improvements and adaptations. This not only fosters creativity but also helps reduce costs, as users can create customized solutions tailored to their specific needs without starting from scratch.
