Using a modular design in hardware offers several benefits, including flexibility, scalability, and ease of maintenance. Each module can operate independently, allowing for easier upgrades or replacements without overhauling the entire system. This also reduces development times and costs, as teams can work on different modules concurrently. Additionally, modular design enhances customization options, enabling users to tailor systems to their specific needs. It facilitates quicker troubleshooting and repairs, limiting downtime and optimizing overall performance. As a result, modular designs are highly adaptable for evolving technological demands.
