Solsta business development engineering team’s Chris Bowers and Gareth Jones explain the commercial and technical benefits of system-on-module solutions.
Disruptions in global supply chains are a persistent issue. As a result, procurement professionals must optimise sourcing while controlling costs. System-on-module (SoM) technology is revolutionising product development in both UK and international markets. These compact circuit boards function as complete computing systems, integrating essential components like processors, memory and connectivity into a single, plug-in module.
Why are organisations embracing SoM solutions?
SoMs offer two key advantages: they simplify the procurement process by consolidating multiple components into one unit, and they significantly reduce development complexity since the core computing functions are pre-integrated and validated. Instead of designing complex computing systems from scratch, manufacturers can focus on their unique product features by simply incorporating a SoM into their carrier board design.
Think of a SoM as a miniature computer that’s ready to be plugged into a larger system, similar to how a memory card slots into a camera, but with much more computing capability. This approach allows companies to leverage SoM providers’ bulk purchasing power and established supplier relationships, cutting costs and mitigating sourcing risks.
SoMs accelerate time-to-market by eliminating lengthy approval processes. This is especially beneficial for UK manufacturers in the EV-charging and medical device sectors, as the use of pre-certified SoMs ensures faster deployment in regulated environments while reducing compliance burdens.
Key considerations when evaluating SoMs
Selecting the right SoM requires assessing both technical specifications and business factors. The module’s form factor should enable easy upgrades and modifications without requiring a complete redesign. Scalability is essential—modern SoMs support multiple processor architectures and memory configurations to allow different product iterations while maintaining a consistent design foundation.
Security is another critical factor. To ensure long-term cybersecurity compliance, identify SoMs with built-in security features and remote firmware update capabilities. Additionally, supplier reliability matters—leading providers offer standardised modules with clear technology roadmaps, ensuring long-term availability and unified transitions to newer technologies.
Best practices for SoM procurement
A structured pilot programme is the best way to validate SoM benefits. Select a product line for implementation and track key metrics such as cost savings, time-to-market and quality improvements. This approach facilitates data-driven decision-making before full-scale adoption.
Lifecycle support must be a key contractual consideration. Partner with providers that offer decade-long availability commitments and flexible upgrade options. Suppliers with robust technical support, including UK-based assistance, simplify integration and troubleshooting.
Beyond the module itself, evaluate the provider’s ecosystem—development tools, technical documentation and engineering support are crucial in overcoming integration challenges and accelerating development.
How SoMs strengthen supply chain resilience
SoM providers act as strategic procurement partners, ensuring component availability through established distribution networks and proactive inventory management. By consolidating multiple components into a single module, they eliminate the risk of production halts caused by shortages of individual parts. Their ability to source alternative components further reduces exposure to supply chain disruptions.
Crucial technical considerations
Smooth integration is vital when selecting a SoM. Ensure compatibility with various connectivity options, including Ethernet, USB, WiFi and Bluetooth. The shift towards eSIMs and iSIMs optimises space and simplifies global connectivity.
Operating system flexibility is another key factor. SoMs that support established platforms like embedded Linux or Android provide greater control over software updates, reducing the risk of vendor lock-in while enabling long-term adaptability.
SoMs are transforming product development by enabling organisations to focus on innovation while outsourcing complex CPU design. With documented cost savings of 20 to 30 per cent and built-in support for emerging technologies like AI and machine learning, they provide a future-proof, cost-efficient path to market. If UK manufacturers want to compete globally, adopting SoMs is the game-changer that delivers the agility and resilience needed to stay ahead.
