In the embedded computing industry, selecting the right technology architecture can significantly impact the success or failure of a project. Many projects still rely on traditional all-in-one SBCs, which integrate all functions into a single board. However, more and more developers are moving toward a modular approach, where a main SBC such as the KIWI330 is combined with MIO boards to expand interfaces, along with middleware that simplifies the interaction between hardware and software.

The difference is crucial: while traditional SBCs provide a fixed, rigid design, the modular architecture of the KIWI330 allows systems to adapt and scale according to project requirements.

Adaptable interfaces

Traditional SBCs come with a closed design, where the user is given a fixed set of interfaces, often including unused ports while lacking others that are critical. If a change is needed, the only option is usually to redesign the board or migrate to a different model, resulting in additional costs and delays.

In contrast, the KIWI330 allows customization through MIO boards, which add only the interfaces required for the project—such as UART, SPI, I²C, GPIO, or PWM. Middleware ensures that these expansions are integrated seamlessly, without requiring the application software to be rewritten. This adaptability makes the platform suitable for industrial automation, IoT, robotics, or AI-enabled vision systems.

Faster time to market

Developing monolithic solutions is typically a long and rigid process: it involves defining specifications early, designing the PCB, validating the hardware, and then creating the required drivers. Any change in requirements can restart the entire cycle.

By contrast, with the KIWI330 modular platform, engineers can start coding immediately. MIO boards are already validated, and middleware provides high-level APIs that reduce the complexity of hardware integration. This accelerates prototyping, allowing software teams to test features from early stages, and shortens the time-to-market.

Lower Costs

One of the key drawbacks of traditional all-in-one SBCs is over-design: they often include interfaces that increase board cost even if they are never used. Additionally, any redesign of the PCB entails high non-recurring engineering (NRE) and manufacturing costs.

The modular approach optimizes costs:

• Projects only pay for the modules they actually need.

• Redesigns of the main board are avoided when new requirements arise.

• Middleware ensures backward compatibility, extending the lifetime of existing software.

In the medium term, this results in significant savings on maintenance, upgrades, and overall project expenses.

Sustainable Life Cycle

Industrial projects often have life cycles of 7–10 years or more. During this period, new connectivity requirements may arise, and traditional SBCs quickly become obsolete.

With the KIWI330 modular approach, it is enough to replace an MIO board or update the middleware to keep the platform aligned with new requirements. Software developed on top of the middleware remains stable even as hardware evolves. This sustainable design not only protects the initial investment but also ensures long-term operational continuity in mission-critical applications.

Future-Ready

Technology standards and protocols evolve rapidly, making forward compatibility a crucial requirement. Unlike rigid SBCs, the KIWI330 platform can be continuously updated with new MIO boards and middleware, ensuring support for future connectivity and protocols.

The compact size of the KIWI330 further enhances its relevance for next-generation embedded designs. Its small footprint makes it ideal for space-constrained applications such as autonomous robots, portable devices, and edge computing nodes, where performance and adaptability to future requirements are critical.

Why KIWI boards?

The comparison between traditional all-in-one SBCs and the KIWI330 modular platform, featuring MIO boards and middleware, highlights a clear strategic choice for modern embedded projects.

Traditional SBCs may be sufficient for simple, static use cases, but they quickly become limiting when requirements change. In contrast, the KIWI330 offers the flexibility of modular I/O expansion, the efficiency of middleware-based software development, and the practicality of a highly compact design that integrates seamlessly into space-constrained applications.

This combination ensures faster prototyping, lower long-term costs, easier maintenance, and resistance to obsolescence. For projects that demand scalability, reliability, and adaptability to future needs, the KIWI330 is not just an SBC; it's a platform designed for the next generation of embedded and industrial systems.
