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. π― 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?
- Whatβs the lifecycle? One-off prototype or long-term production?
- Any size, temperature, or power constraints?
β Example: For a smart home controller, you might prioritize Wi-Fi, low power usage, and touchscreen support.
2. π§ Processing Performance
Choose a CPU that matches your task complexity:
Task | Recommended SoC |
---|---|
Simple control logic | ARM Cortex-A7 or A55 |
Multimedia & UI | Cortex-A72 or RK3566 |
AI edge processing | SoC with NPU (e.g., RK3588) |
Also consider RAM size (1β8GB typical) and storage type (eMMC, SD, NVMe).
3. π 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
π§© If your project requires camera input and real-time display, confirm CSI & DSI support.
4. πΆ 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. π§° 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
π‘ Rockchip-based SBCs often have Android and Linux dual support with active developer communities.
6. π Mechanical Size & Power
- Form factor: Credit card size (e.g., Raspberry Pi) or larger (3.5β or Pico-ITX)
- Mounting: DIN rail, VESA, panel-mount?
- Power: 5V vs 12V input; passive or active cooling?
β οΈ For battery-powered devices, power draw must be <5W ideally.
7. π° Cost vs Longevity
Donβt just choose the cheapest SBC. Look at:
- Long-term availability (3+ years)
- Support for hardware revision tracking
- Documentation & community
- EOL (end-of-life) roadmap
