How to Select the Right Embedded SoM Board for Your Product Design

In the fast-moving world of embedded design, your choice of computing hardware lays the foundation for everything that follows. From performance and power efficiency to software support and cost, selecting the right Embedded SoM Board is one of the most critical decisions you’ll make.

Unlike traditional single-board computers or fully custom PCB designs, a System-on-Module approach offers a balanced mix of standardization and adaptability. These compact modules integrate processing units, memory, and essential I/O into a single package that connects to a custom carrier board—giving developers both structure and freedom.

This separation accelerates prototyping, streamlines scaling, and simplifies future upgrades. But how do you choose the right platform? Let’s walk through the key decision points to guide your selection process.

Understand Your Product Requirements First

Before diving into specifications, define the functional goals of your application. Begin by asking:

• What is the primary workload? (e.g., real-time control, AI processing, media streaming)
• What is your power envelope? Is the device battery-powered or always connected?
• What environmental factors must the system endure—vibration, temperature, humidity?
• What peripherals, displays, or external devices need to connect to the board?

Mapping out these core requirements will give you a baseline to match with potential SoM candidates.

What Is an Embedded SoM Board and Why Use One?

A System-on-Module is a pre-integrated computing platform that contains the processor, RAM, flash storage, and essential interfaces in a standardized form factor. These boards are designed to mount onto application-specific baseboards, making it easier to customize hardware without rebuilding the core processing unit.

Why are they widely adopted?

• They reduce time-to-market
• Simplify hardware design
• Allow scalable product families
• Support long-term availability in industrial markets

Unlike DIY SBCs, SoMs are often accompanied by production-grade documentation, board support packages (BSPs), and lifecycle support—ideal for commercial products that require stability and longevity.

Consider Processor Architecture and Performance Needs

The heart of any SoM is its processor. Your workload will determine whether you need a lightweight Cortex-A7 for basic tasks or a powerful Cortex-A76 or multi-core ARM SoC for AI inference, vision processing, or complex control loops.

Here’s what to evaluate:

• CPU core type and clock speed
• GPU/NPU acceleration for edge AI
• Real-time processing requirements (e.g., for motor control or safety-critical tasks)
• Number of concurrent tasks and memory footprint

Also, keep an eye on thermal design power (TDP)—a high-performance chip might require active cooling, which could affect your enclosure and thermal management strategy.

Evaluate I/O, Interface, and Expansion Capabilities

Your application determines what connectivity options you’ll need. When reviewing SoM solutions, consider:

• High-speed interfaces: USB 3.0, PCIe, SATA
• Industrial protocols: RS232, RS485, CAN
• Media: HDMI, MIPI DSI/CSI, audio codecs
• Storage: SD, eMMC, NVMe
• Networking: Ethernet, Wi-Fi, Bluetooth, LTE modules

Make sure the SoM supports enough flexibility to connect the sensors, displays, and expansion modules you plan to use—both now and in future versions.

Power Efficiency and Thermal Design Considerations

Power consumption is a key concern in mobile, fanless, and remote installations. A module with efficient power management can help extend battery life, reduce heat, and lower total system cost.

Factors to review:

• Typical power draw under load
• Support for sleep/idle states
• Thermal envelope: passive vs active cooling
• Power management ICs and profiles

Many SoM vendors offer thermal design guides—an important asset when optimizing your product for sealed enclosures or outdoor environments.

Operating System and Software Ecosystem Support

The availability of stable BSPs (Board Support Packages) and development tools can make or break your product schedule. Ensure your chosen compute platform supports your preferred OS, such as:

• Linux (Yocto, Debian, Ubuntu)
• Android
• RTOS for real-time or safety-critical tasks

Evaluate the quality of SDKs, documentation, sample code, and community support. A solid software stack reduces engineering burden and improves long-term maintainability.

Longevity, Compliance, and Supply Chain Assurance

For commercial and industrial projects, longevity and supply continuity are critical. Choose a vendor that can offer:

• Long-term availability (5–10 years or more)
• RoHS, CE, FCC, or other relevant certifications
• Secure boot and hardware-level security
• Transparent lifecycle and revision policies

Ask vendors about end-of-life (EOL) strategies and second-source availability to avoid future disruptions.

Real-World Use Cases: Tailoring SoMs to Industry Needs

Different industries prioritize different factors. A few examples:

• Medical Devices: Need long lifecycle support, FDA-friendly documentation, and low EMI designs
• Factory Automation: Favor rugged interfaces like CAN and wide temperature support
• Smart Transportation: Require high reliability, GNSS integration, and AI acceleration for vision tasks
• Retail and Signage: Value GPU performance for media playback and flexible display support

Understanding your vertical helps in choosing a compute module that aligns with both technical and compliance needs.
