What Does SoM Stand For?

SoM stands for System on Module. It is a compact, integrated computing solution that includes essential components such as a processor (CPU), memory (RAM), storage, and I/O interfaces. SoMs are designed to be embedded into larger systems, offering modularity, scalability, and faster development cycles for electronic and industrial applications.

An SoM functions as the core computing unit of a device, similar to a single-board computer but designed for integration into a custom carrier board. The carrier board provides additional connectivity, power management, and specific I/O interfaces tailored to the final application.

Faster Time to Market – Reduces development time by providing a ready-made computing core.

Compact and Efficient – Saves space and power compared to traditional computing setups.

Scalability – Easily upgraded or customised by swapping the SoM while keeping the same carrier board.

Reduced Development Costs – Lowers R&D expenses as the processing unit is pre-designed and optimised.

Long-Term Availability – Many industrial-grade SoMs offer extended lifecycle support for embedded applications.

SoMs are widely used in various industries, including:

Industrial Automation – Controls machinery and processes in factories.

Medical Devices – Powers diagnostic and monitoring equipment.

Automotive Systems – Used in infotainment, ADAS, and vehicle control units.

AI and Edge Computing – Provides efficient processing for AI-powered applications.

IoT (Internet of Things) – Enables smart devices with connectivity and computing power.

Aerospace and Defence – Used in mission-critical and rugged computing environments.

While both provide computing capabilities, an SoM is designed for integration into custom carrier boards, offering greater flexibility and scalability. In contrast, SBCs (such as Raspberry Pi) are standalone solutions with all components fixed on a single board, making them less modular.

Leading companies producing SoMs include:

NVIDIA (Jetson series – AI and edge computing)

Intel (IoT and embedded solutions)

Variscite (Industrial-grade ARM-based SoMs)

Toradex (Scalable embedded computing)

Advantech (Industrial automation and AI)

No, an SoC (System on Chip) is a single silicon chip that integrates a processor, GPU, memory, and other components, while an SoM is a modular board that houses an SoC along with additional components like RAM, power management, and storage interfaces.

A System on Module (SoM) is a powerful, modular computing solution that accelerates development, reduces costs, and enhances scalability for industrial, AI, and embedded applications.
