ARM Single Board Computers (SBCs) are reshaping how industries design and deploy intelligent systems. From industrial automation and smart home hubs to advanced medical devices and retail POS systems, SBCs offer the flexibility, scalability, and power efficiency required for today’s connected world.
For a more detailed introduction to SBCs, including hardware platforms, display interfaces, and OS choices, you can explore this comprehensive resource: Embedded SBC Overview.
What Is an Embedded SBC?
An Embedded SBC is a compact, self-contained computer that integrates processing, memory, I/O, and storage on a single printed circuit board. Unlike general-purpose desktop PCs, SBCs are optimized for specific embedded applications, such as:
- Controlling industrial machinery
- Running intelligent home automation panels
- Managing data acquisition in medical equipment
- Powering interactive kiosks and POS terminals
SBCs are designed for long lifecycle support, high reliability, and low power consumption, making them ideal for harsh environments and mission-critical systems.
Hardware Platforms
Choosing the right System-on-Chip (SoC) platform is a key step in building an embedded system.
STMicroelectronics
ARM Cortex-based, low-power SoCs used in automotive, industrial, and home automation. Known for STM32 series and strong peripheral integration.Rockchip
Multimedia-focused SoCs with powerful GPU and video capabilities. Ideal for Android-based HMIs and smart devices. Common models include RK3566, PX30, and RK3399.Allwinner
Balanced cost-performance SoCs, widely used in smart displays and entry-level Android boards.NXP
Long-lifecycle i.MX series SoCs, used in automotive dashboards, industrial HMIs, and medical imaging systems.
Display Interfaces
SBCs can drive multiple types of displays. Choosing the right interface depends on resolution needs, latency, cable length, and EMI considerations.
- HDMI – High-definition video/audio, ideal for external monitors and digital signage.
- RGB Interface – Parallel connection for low-latency TFT LCDs in industrial HMIs.
- LVDS – Noise-resistant, long-cable display connection for automotive and industrial panels.
- MIPI DSI – High-speed serial interface, common in smartphones and compact control panels.
- eDP – Power-efficient, high-bandwidth option for 4K+ embedded displays.
Operating Systems
The OS determines system capabilities, development ease, and community support.
- Linux – Modular, open-source, and customizable via Buildroot or Yocto. Ideal for industrial and IoT projects.
- Android – Rich GUI and app ecosystem, perfect for touch-enabled devices. Read more about the trade-offs in this Android SBC vs Linux SBC comparison.
- RTOS – Real-time control for mission-critical, low-power systems such as medical monitors or automotive ECUs.
Custom Embedded Systems
Off-the-shelf SBCs may not always match your exact requirements. Custom SBC development allows:
- Tailored CPU, GPU, and RAM configurations
- Custom I/O (UART, CAN, USB, Ethernet, GPIO)
- Specific display interface support
- Optimized power delivery and thermal design
- Custom OS images and bootloader configurations
This approach ensures optimal performance, cost control, and maintainability.
Applications of Embedded SBCs
SBCs are deployed in a wide range of sectors:
- Home Automation – Lighting control, HVAC systems, smart security, and AI voice assistants.
- Industrial HMI – Real-time process control, robotics, and factory dashboards.
- Medical Devices – Portable analyzers, diagnostic imaging, and patient monitoring.
- Retail & POS – Payment terminals, barcode scanners, and digital kiosks.
Conclusion
Embedded SBCs are the backbone of modern edge computing. They bring together computing power, connectivity, and display integration into a compact, reliable package.
