Single Board Computers (SBCs), Computer On Module (COM)

1. Overview

Embedded computers are specialized computing systems designed for specific tasks within larger mechanical or electrical systems. Single Board Computers (SBCs) integrate all computer components on a single circuit board, providing a compact and self-contained solution. Computer On Module (COMs) are standardized modules containing core computing components, designed to be integrated into carrier boards for customized applications. These technologies are critical in industrial automation, IoT, robotics, and edge computing due to their reliability, scalability, and space efficiency.

2. Main Types and Functional Classification

TypeFunctional CharacteristicsApplication Examples
SBC (e.g., Raspberry Pi)Complete system with CPU, RAM, storage, and I/O interfacesSmart home devices, educational tools
COM (e.g., COM Express)Modular design with processor, memory, and basic I/O; requires carrier boardMedical imaging systems, industrial controllers
Industrial SBCRuggedized components for harsh environmentsFactory automation, outdoor kiosks

3. Structure and Components

A typical SBC includes a processor (ARM/x86), RAM, flash storage (eMMC/NOR), power management unit, and interfaces (USB, HDMI, GPIO). COMs feature a dense layout with SoC (System on Chip), DDR4 memory packages, thermal dissipation layers, and high-speed connectors. Both utilize PCB substrates with multi-layer routing for signal integrity.

4. Key Technical Specifications

ParameterDescriptionImportance
CPU PerformanceMeasured in DMIPS or GHzDetermines processing capability
Thermal Design Power (TDP)Power consumption in wattsImpacts cooling requirements
Interface TypesUSB 3.0, PCIe, CAN, etc.Dictates peripheral compatibility
Operating Temperature-40 C to +85 C rangeDefines environmental tolerance

5. Application Areas

  • Industrial: CNC machines, PLC controllers
  • Healthcare: Patient monitoring systems, diagnostic equipment
  • Transportation: In-vehicle infotainment, ADAS
  • Smart Cities: Surveillance cameras, environmental sensors

6. Leading Manufacturers and Products

AdvantechAIMB-236 SBCIntel Atom x6425E, -20 C to 70 C operation

7. Selection Guidelines

Consider processing requirements, power constraints, environmental conditions, and long-term availability. For industrial applications, prioritize extended temperature ranges and RoHS compliance. Evaluate ecosystem support (OS compatibility, SDKs) and choose modular designs for future upgrades.

8. Industry Trends

Key trends include AI integration at the edge, adoption of RISC-V architecture, increased use of heterogeneous computing (CPU+GPU+NPU), and standardization of COM interfaces (e.g., SMARC 2.0). Energy efficiency improvements and cybersecurity features are becoming critical for IoT deployments.
