How to Choose an ARM Single Board Computer
-
Form Factor and Carrier Boards
Decide whether you need an all-in-one standalone board or a modular compute card. Standard single board computers feature full-sized USB, Ethernet, and video ports soldered directly to the PCB. In contrast, compute modules omit standard external connectors. The Raspberry Pi Compute Module 5 16GB RAM 16GB eMMC requires a separate carrier board to break out interfaces and power. If you design custom industrial hardware or specialized enclosures, compute modules offer compact integration. For straightforward desktop testing, choose a board with standard connectors.
-
Integrated Displays and Sensors
Determine if your build requires built-in peripherals or external peripherals. Most ARM boards require you to connect a separate monitor, keyboard, and sensor modules through GPIO pins or USB ports. However, all-in-one designs simplify portable and educational deployments. The DFRobot UNIHIKER ARM Single Board Computer includes an integrated touchscreen and onboard sensors directly on the board. This configuration allows you to program and monitor the system without external display hardware. If you need a compact handheld interface, prioritize boards with onboard displays.
-
Firmware and Boot Flexibility
Check how the board initializes and loads operating systems from storage. Many ARM platforms rely on proprietary bootloaders that complicate operating system setup across different drives. Boards supporting standard UEFI firmware simplify deployment by allowing standard operating system installers to run seamlessly from external media. The Libre Computer Sweet Potato 2GB SBC provides flexible UEFI storage booting for reliable system initialization. If you run persistent servers requiring clean operating system installs, look for boards with standardized UEFI support.
-
Architecture and Word Size
Examine whether the ARM processor uses a 32-bit or 64-bit architecture. While 64-bit ARM processors handle modern software distributions and large datasets effectively, specialized embedded systems often prioritize low-overhead microarchitectures. The KLAYERS Luckfox Lyra Ultra Linux Board uses heterogeneous CPU cores tailored for embedded Linux development without 64-bit execution. If your workload involves compiling complex applications, select a 64-bit ARM processor. For dedicated microcontroller replacement or targeted embedded logic, compact heterogeneous designs provide sufficient computing power.
-
Operating System Distribution Support
Verify which operating system images the board supports out of the box. Single board computers depend on specific kernel builds and device tree files for hardware initialization. Certain models arrive with pre-configured Linux distributions like Ubuntu, while others demand custom kernel compilation. The Banana Pi Allwinner H618 SBC supports Ubuntu, providing access to familiar package managers and precompiled binaries. If you want a fast setup without building board-support packages, choose boards with official distribution support.
Frequently asked questions
Which ARM single board computers support 4K video output?
You can get 4K display output from several models on this list. The Libre Computer Sweet Potato 2GB SBC provides hardware 4K media decoding, while the Banana Pi Allwinner H618 outputs 4K in a small footprint. For multi-display setups, the Raspberry Pi Compute Module 5 supports dual 4K video output via compatible carrier hardware.
Can you program an ARM single board computer without an external monitor?
Yes, you can run ARM boards headlessly or select a board with an integrated screen. The DFRobot UNIHIKER includes an onboard touchscreen and built-in sensors, allowing standalone Python development directly on the device. Other boards can be accessed headlessly across a local network using standard remote terminal protocols over Ethernet or wireless.
What onboard storage options are available on ARM single board computers?
Storage configurations range from boards without integrated flash to large flash capacities. The Libre Computer La Frite includes no onboard eMMC storage. In contrast, the Banana Pi Allwinner H618 provides 8GB of eMMC flash, while the Raspberry Pi Compute Module 5 offers onboard configurations featuring either 16GB or 64GB of eMMC storage.
Which ARM single board computer has the lowest power consumption?
The Libre Computer Sweet Potato 2GB SBC offers the lowest power profile, idling at approximately 1W. The Libre Computer La Frite is also built for low-draw applications, operating at an active 2W power draw. These low thermal and electrical requirements make them suitable for continuous 24/7 background tasks.
What operating systems run on these ARM single board computers?
Most ARM single board computers run specialized or mainstream Linux distributions. The Banana Pi Allwinner H618 lists explicit compatibility with Ubuntu, while the KLAYERS Luckfox Lyra Ultra is tailored for embedded Linux development. Additionally, the Libre Computer Sweet Potato features standard UEFI storage booting, simplifying standard OS installation workflows.
Which ARM board provides the highest system memory capacity?
The Raspberry Pi Compute Module 5 offers up to 16GB of onboard RAM. While entry-level and compact boards such as the Libre Computer La Frite provide 1GB or 2GB of RAM, jumping to a 16GB memory footprint gives you substantial capacity for heavy multitasking and data-intensive embedded applications.
When should you choose a non-64-bit ARM single board computer?
You should choose a non-64-bit board when you need dedicated hardware control rather than high-throughput computing. The KLAYERS Luckfox Lyra Ultra uses heterogeneous cores for targeted embedded development without 64-bit overhead. If your software requires standard 64-bit computing, boards like the Libre Computer La Frite provide a quad-core 64-bit architecture.
