As we kick off 2026, the embedded systems landscape is defined by a shift toward "modular-first" design. System on Modules (SoMs) / Computer on Modules(CoMs) have become the gold standard for navigating the dual pressures of increasing computational demands and shrinking time-to-market windows.
What is a System on Module (SoM)?
A System on Module (SoM) is a compact, production-ready computing platform that integrates the "brain" of an embedded system-processor, memory, power management (PMIC), and core interfaces—onto a single PCB.
By utilizing a SoM, engineering teams can offload the high-speed signal integrity and complex power-sequencing challenges of the core processing unit, allowing them to focus on the carrier board design and application-specific software.
Why SoMs are Dominating in 2026
In 2026, the "Make vs. Buy" debate has tipped heavily toward "Buy" for several reasons:
Design Velocity: Drastically reduces the hardware development cycle.
Scalability: Many System on Module’s follow industry standards allowing for easy CPU upgrades without redesigning the baseboard.
Risk Mitigation: SoMs come pre-validated for signal integrity and often carry pre-certified wireless modules.
Long Lifecycle: Leading vendors offer 10–15 year availability, essential for industrial and medical sectors.
Key Players: The 2026 SoM Ecosystem
The market is currently categorized by three distinct types of providers:
- PHYTEC
- Toradex
- Variscite
- Rugged Board
- Advantech
- Kontron
- Congatec
- SECO
- ADLINK
- SolidRun
- Octavo Systems
Selection Criteria for 2026 Projects
When evaluating a System on Module provider this year, look beyond the datasheet. Consider these five pillars:
Form Factor Standards: Will you use a proprietary pin-out or an industry standard like SMARC 2.1, OSM (Open Standard Module), or COM-HPC?
Software Ecosystem: Does the vendor provide a Mainline Linux kernel, Yocto Project layers, or a containerized OS
Security Integration: In 2026, hardware-based "Root of Trust" and encryption support are non-negotiable for IoT edge devices.5
Thermal Management: As edge AI performance increases, evaluate the module’s thermal dissipation efficiency at high loads.
Supply Chain Transparency: Ensure the manufacturer provides clear "End of Life" (EOL) roadmaps.
Looking Ahead
The SoM market in 2026 is no longer just about hardware; it is about the total solution. The most successful designs this year will be those that leverage the robust software stacks and long-term support cycles provided by established leaders like PHYTEC,Toradex ,Variscite, Advantech,Kontron.
Conclusion
System on Modules have become the cornerstone of modern embedded design, offering speed, scalability, and reliability in an increasingly competitive market. In 2026, success will depend on choosing the right SoM partner—one that provides not just hardware, but a complete ecosystem of software, security, and long-term support. Whether you’re building industrial automation, medical devices, or edge AI solutions, adopting a modular-first approach is no longer optional—it’s the future.
*Happy New Year 2026! May your hardware be stable, your latency low, and your product launches seamless. *
