The hardware segment of the embedded systems market is projected to reach a value of USD 120 billion by 2034, driven by the rapid adoption of Industrial IoT (IIoT), edge computing, and AI-driven automation. As industries increasingly rely on embedded computing solutions, selecting the right architecture—System-on-Module (SOM), Computer-on-Module (COM), or Single Board Computer (SBC)—has become a critical decision for engineers and system integrators. Each option has unique advantages, making it essential to understand their differences in order to optimize performance, scalability, and cost-efficiency for specific applications.

This blog will provide a technical comparison of SOM, COM, and SBC, guiding you in selecting the most suitable solution for your specific application or project.

1. What Are SOM, COM, and SBC? 

1.1 A Technical Overview

A System-on-Module (SOM) is a compact, integrated computing module that includes essential components such as the processor (CPU/SoC), RAM, storage, and I/O interfaces. A Computer-on-Module (COM) is similar to a SOM but follows industry standards such as COM Express, SMARC, and Qseven. Both SOMs and COMs require a carrier board to route the signals from the modules and provide additional connectivity and custom features. Due to their compact design and minimum circuity, the price can be attractive.

Overview of SMARC, Q-Seven and OSM Standard

The modularity of SOMs and COMs allows for scalability and upgradability, as the module can be replaced independently of the carrier board. However, the variability in standards can limit cross-industry compatibility.

A Single Board Computer (SBC) is a fully integrated computer on a single circuit board, including the processor, RAM, storage, and I/O interfaces. Unlike SOMs and COMs, an SBC does not require an external carrier board and can operate as a standalone system. SBCs are ideal for applications where simplicity and rapid deployment are prioritized.

2. How to Choose the Right Solution for Your AIoT and Edge Computing Applications?

2.1 When to Choose SOM or COM?

SOMs or COMs are ideal for projects that require scalability, compact designs, and low-power operation. If your project needs compact and low-power designs for IoT or edge AI applications and requires highly customized embedded solutions, a SOM or COM offers the flexibility needed to meet these demands.

For example, Vantron’s ARM-based SOMs comply with the OSM 1.1 Standard, making them customizable for diverse scenarios, from common applications to demanding AI applications. These SOMs are widely used in retail, healthcare, smart home, industrial automation, and AI robotics, featuring streamlined design, seamless integration, and flexible deployment. Additionally, Vantron provides long lifecycle support, ensuring reliability for industrial applications.

2.2 When to Choose SBC? 

An SBC is a ready-to-use embedded system that minimizes integration efforts, making it ideal for projects where time-to-market is critical. SBCs do not require additional hardware development, assuming they meet the required specifications. This makes them a cost-effective solution for low-to-medium volume deployments.
Vantron’s industrial SBCs are designed for high stability and feature flexible designs tailored to specific project requirements. These SBCs are built to withstand harsh environments, offering ruggedness and extended temperature ranges for industrial-grade conditions. They are particularly suited for applications such as industrial HMIs, edge computing gateways, and medical equipment.
