A System on Module (SoM) is a board that integrates a processor (or SoC), memory (RAM, storage), power and often connectivity in a compact, standardized form factor. It connects to a carrier board that provides interfaces, connectors and product-specific functions.
Benefits in industrial products
It reduces design time and risk: the processing core is already validated, certified and supported for the long term. It allows resources to focus on the application, interfaces and integration. It makes it easier to upgrade the processor by changing only the module if the standard (e.g. COM connector) is maintained.
When to use it
It is especially useful when high performance, multiple cores or complex interfaces (PCIe, Ethernet, USB, etc.) are needed and the core is not to be designed from scratch. Also when extended temperature ranges, rugged packaging or certifications that the SoM vendor already offers are required.
- Speed up development and reduce technical risk
- Keep processor upgrades without redesigning the whole board
- Leverage modules already validated for industry, EMC or temperature
