Unlocking the Power of SOMs: A Guide to System on Modules

What is a SOM? Understanding System on Modules and Their Applications

In today’s fast-paced industrial and embedded computing world, compact yet powerful solutions are essential. One of the key technologies driving this trend is the System on Module (SOM). But what exactly is a SOM, and why is it becoming a staple in industrial applications?

What is a System on Module (SOM)?

A System on Module (SOM), sometimes also referred to as a Computer-on-Module (COM), is a compact, integrated circuit board that combines the core components of a computer into a single module. This typically includes the processor, memory, storage, and essential interfaces. SOMs are designed to simplify the development of embedded and industrial systems, allowing engineers to focus on building application-specific hardware rather than designing every component from scratch.

By using a SOM, companies can accelerate product development, reduce costs, and ensure long-term scalability.

Types of System on Modules

SOMs come in different architectures, each suited to particular applications:

SOM Type	Key Strength	Common Applications
x86	High performance, legacy support	Industrial PCs, Medical devices
ARM	Low power, energy-efficient	IoT devices, portable embedded systems
Jetson	AI and GPU acceleration	Robotics, vision systems, AI edge computing

Popular SOM Form Factors

Beyond processor architecture, SOMs are available in different form factors, which define size, connector type, and compatibility with carrier boards:

• COM Express – A widely adopted x86 standard with high-performance processors and multiple I/O options. Ideal for industrial PCs, medical devices, and automation systems. COM Express comes in several module types to suit different size and performance requirements:
  • Basic – Larger module with maximum I/O connectivity and memory support, ideal for high-performance industrial and medical applications.
  • Compact – Mid-sized module balancing performance and space efficiency, commonly used in embedded systems with moderate I/O needs.
  • Mini – Smallest form factor for space-constrained designs, providing essential functionality with reduced footprint for compact embedded applications.
• SMARC (Smart Mobility Architecture) – Compact and low-power ARM-based modules designed for mobile and IoT applications.
• Qseven – Small, energy-efficient modules supporting ARM and x86 processors, perfect for embedded and portable devices.
• COM-HPC – The next-generation high-performance COM standard for demanding industrial and AI edge computing applications. Supports PCIe Gen 5, high-speed networking, and powerful CPUs/GPUs for maximum performance.
• Jetson Modules – NVIDIA SOMs specifically designed for AI, robotics, and GPU-intensive applications with accelerated graphics and deep learning support.
• Raspberry Pi – Popular developer platform often used for prototyping and learning embedded systems. While not a full industrial SOM, it provides an accessible environment for testing and development.

Understanding the right SOM form factor is crucial to designing a system that balances size, performance, and power consumption.
