How to Choose the Right Single-Board Computer (SBC) for Your Project

Single-board computers (SBCs) come in all shapes, sizes, and capabilities. From simple automation tasks to AI-driven edge computing, choosing the right SBC can save development time, reduce cost, and ensure long-term reliability.

This guide outlines the key factors to consider when selecting the best SBC for your embedded or industrial project.


1. 🎯 Define Your Application Requirements

Before looking at technical specs, ask:

  • What will the SBC do? Data collection? Display UI? AI inference?
  • What environment will it run in? Indoor, outdoor, harsh industrial?
  • What’s the lifecycle? One-off prototype or long-term production?
  • Any size, temperature, or power constraints?

βœ… Example: For a smart home controller, you might prioritize Wi-Fi, low power usage, and touchscreen support.


2. 🧠 Processing Performance

Choose a CPU that matches your task complexity:

TaskRecommended SoC
Simple control logicARM Cortex-A7 or A55
Multimedia & UICortex-A72 or RK3566
AI edge processingSoC with NPU (e.g., RK3588)

Also consider RAM size (1–8GB typical) and storage type (eMMC, SD, NVMe).


3. πŸ”Œ I/O and Interfaces

Check the availability of:

  • USB ports (2.0, 3.0)
  • HDMI / LVDS / MIPI-DSI for displays
  • GPIO, UART, I2C, SPI for sensors
  • Ethernet (10/100/1000 Mbps)
  • Audio in/out
  • PCIe or M.2 for expansion

🧩 If your project requires camera input and real-time display, confirm CSI & DSI support.


4. πŸ“Ά Networking & Wireless Connectivity

Must-have for most IoT and mobile applications:

  • Wi-Fi 2.4/5GHz β€” many SBCs have onboard chips or M.2 sockets
  • Bluetooth β€” often included with Wi-Fi
  • 4G/5G β€” via USB dongle or SIM slot on advanced SBCs
  • Ethernet β€” always recommended for industrial reliability

5. 🧰 Software & OS Support

Ensure your target SBC supports:

  • Linux (Ubuntu, Debian, Buildroot)
  • Android (for UI-intensive projects)
  • Driver availability for peripherals
  • SDKs and sample code

πŸ’‘ Rockchip-based SBCs often have Android and Linux dual support with active developer communities.


6. πŸ— Mechanical Size & Power

  • Form factor: Credit card size (e.g., Raspberry Pi) or larger (3.5” or Pico-ITX)
  • Mounting: DIN rail, VESA, panel-mount?
  • Power: 5V vs 12V input; passive or active cooling?

⚠️ For battery-powered devices, power draw must be <5W ideally.


7. πŸ’° Cost vs Longevity

Don’t just choose the cheapest SBC. Look at:

  • Long-term availability (3+ years)
  • Support for hardware revision tracking
  • Documentation & community
  • EOL (end-of-life) roadmap
