Cortex-A sınıfı SoC'leri kullanarak yüksek performanslı gömülü ürün geliştirmede, starting entirely from scratch requires tremendous effort — from PCB layout and hardware debugging to system stabilization and final mass production. This path not only brings significant technical challenges but also risks costly PCB redesign cycles, which could cause missed market windows.
Fortunately, the industry already offers more mature solutions: leveraging proven Single Board Computers (SBCs) or System-on-Modules (SoMs) for secondary development. These options allow developers to bypass complex low-level hardware work and jump straight into product definition and application development. Fakat, many still face a dilemma: Should we choose a feature-rich, plug-and-play SBC to speed time-to-market, or a flexible, cost-efficient SoM that allows hardware customization? To answer this question, we must first clarify the fundamental differences between SBCs and SoMs.
What Are SBCs and SoMs?
1. Single Board Computer (SBC): A “Mini Computer” That Just Works
An SBC is a fully integrated computing system that brings together the CPU, memory, storage, power management, and interfaces (USB, Ethernet, HDMI, Wi-Fi, vesaire.) all on a single circuit board. It can independently run an operating system (Linux, Android, vesaire.) without requiring additional hardware.
Typical Examples: Raspberry Pi, BeagleBone, Advantech industrial SBCs, Tronlong RK3562 industrial SBC.
Key Features:
✅ Plug-and-play: Preloaded with OS and drivers, no extra hardware design needed.
✅ Rich interfaces: Integrated USB, HDMI, Ethernet, GPIO, and more for rapid prototyping.
✅ Certifications ready: Many industrial SBCs are pre-certified (CE, FCC, ROHS), saving compliance costs.
❌ Limited expandability: May lack high-speed PCIe or specialized sensor interfaces without add-on boards.
2. System-on-Module (SoM): A Compact and Flexible Computing Core
A SoM is a stripped-down computing module that typically integrates only the CPU, memory, storage, and power management. It lacks complete peripheral interfaces and connects to a custom carrier board through board-to-board connectors (stamp holes, edge fingers, vesaire.), with the carrier providing application-specific interfaces (USB, Ethernet, display, vesaire.).
Typical Examples: NXP i.MX SoMs, TI AM6x SoMs, ST STM32MP1 SoMs, Tronlong RK3562 SoM.
Key Features:
✅ High flexibility: Custom carrier boards allow tailored interfaces for diverse applications.
✅ Optimized for mass production: Core module reused across projects, carrier customized for cost reduction.
✅ Industrial-grade reliability: Tested for temperature, titreşim, and EMC, suitable for demanding environments.
❌ Higher development complexity: Requires custom carrier design, PCB layout expertise, and signal integrity analysis.
❌ Longer development cycles: More time needed for hardware design and driver adaptation.
SBC vs. SoM: A Development Model Comparison
| Boyut | SBC (Single Board Computer) | SoM (System-on-Module) |
|---|---|---|
| Hardware Design | Ready to use, no extra design required | Custom carrier board needed |
| Software | Preloaded OS and drivers | Requires adaptation for custom board |
| Uygunluk | Typically pre-certified (CE/FCC, vesaire.) | Carrier board requires certification |
| Development Cycle | Hızlı (days to weeks) | Longer (weeks to months) |
| Maliyet | Higher per-unit, ideal for small volume | Lower long-term cost in large volume |
| Best Use Cases | Prototyping, education, light industry | Sanayi, medical, automotive, mass production |
How to Choose: The Best Fit for Different Scenarios
✅ When to Choose SBCs
✔ Rapid prototyping (university projects, startups validating MVPs).
✔ Rich interface needs (HDMI, USB, Wi-Fi, Ethernet).
✔ Small production runs (hundreds of units).
✔ No in-house hardware design team.
Typical Applications:
-
Smart home prototypes (smart plugs, thermostats).
-
Industrial site monitoring (basic sensor collection).
-
Educational labs (Linux/embedded system training).
✅ When to Choose SoMs
✔ Highly customized designs (industrial, medical, military applications).
✔ Large-scale production (10,000+ units annually).
✔ Industrial-grade reliability (wide temperature range, titreşim, EMC compliance).
✔ Strong hardware engineering team.
Typical Applications:
-
Industrial automation (PLCs, robotics).
-
AI edge computing (industrial vision inspection).
-
Medical devices (portable diagnostic instruments).
-
Automotive electronics (dashboards, ADAS computing).
