What Is an Open Source ARM Motherboard? Benefits & Use Cases

As embedded systems evolve to become smarter, more flexible, and highly connected, developers are searching for better ways to design products with transparency, full control, and long-term adaptability. One technology gaining strong traction is the open source ARM motherboard.

By combining the energy-efficient and scalable power of ARM architecture with the openness of hardware freedom, these boards give developers, engineers, and innovators the tools to create systems that are faster, smarter, and more secure — without being tied down by closed, proprietary platforms.

In this guide, we’ll break down what open source ARM motherboards are, how they function, the unique advantages they offer, and the real-world industries and applications where they make the biggest impact.

What Does “Open Source” Mean for Motherboards?

When people talk about “open source” in computers, they usually mean software. But when they talk about “open source” in hardware, they mean that everyone may see and access the design and implementation of a motherboard.

An open source ARM motherboard usually has:

• Open circuit diagrams and PCB layouts
• Bootloaders and firmware that are open source, such U-Boot or Coreboot
• Support for open-source software like Linux, Android, and FreeRTOS
• Drivers and tools that are kept up by the community

By removing proprietary barriers, these boards allow anyone to study, modify, and improve the hardware and software stack — making them ideal for prototyping, secure applications, and long-term deployments.

Why ARM Architecture?

ARM processors dominate the embedded and mobile markets due to their low power consumption, performance-per-watt advantage, and licensing flexibility.

Key reasons ARM is preferred in open source hardware:

ARM’s modular licensing also means multiple manufacturers can create SoCs and development boards with varying degrees of openness, giving developers more choices.

Core Features of Open Source ARM Motherboards

Let’s look more closely at what makes an ARM motherboard “open source,” not just the schematics.

Designing hardware that is clear

Open source boards usually post:

• All the schematics and board layout files
• BOM (Bill of Materials)
• Drawings of enclosures or mounts that are mechanical
• Expansion interface pinouts (GPIO, I2C, SPI, and UART)

This lets OEMs and engineers:

• Make different versions of hardware
• Make daughterboards or add-on modules for the design.
• Check the hardware for quality and compliance

Open Firmware and Bootloaders

Open source ARM boards don’t have locked BIOS or UEFI; instead, they use

• U-Boot for systems that run Linux
• Coreboot for apps that care about security
• TF-A or OP-TEE for environments where execution is trusted

This means you can change how the computer starts up, turn on secure boot, or boot from storage devices that you own.

Linux and Android Compatibility

Most open ARM boards support:

• Mainline Linux kernel or BSP (Board Support Package)
• Debian, Ubuntu, Yocto Project, and Buildroot
• Android 7–13, especially for touch-based UIs
• Real-time operating systems (FreeRTOS) for industrial applications

Many boards are even pre-integrated with ROS (Robot Operating System) or TensorFlow Lite for AI/robotics use.

Customization and Developer Control

Unlike proprietary motherboards that restrict firmware and software customization, open source ARM boards give full control over:

• Bootloader parameters
• Kernel modules and drivers
• GPIO behavior and peripheral support
• Memory and storage options

This is invaluable when building tailored systems or deploying hardware at scale.

Benefits of Open Source ARM Motherboards

Open hardware has both technical and strategic benefits, whether you’re making a proof-of-concept or scaling up an industrial solution.

Full Transparency of Hardware

In fields like defense, finance, and healthcare, security and compliance mean knowing exactly what is running in the system.

Open boards:

• Lower the risks in the supply chain
• Let full security audits happen
• Make firmware and silicon trustworthy

Less expensive to develop

You can get free access to schematics, firmware, and OS support:

• No fees for licensing firmware
• Less NRE (non-recurring engineering)
• Prototyping faster with CAD files that are already available

Along with ARM’s energy efficiency, this lowers the BOM and TCO (Total Cost of Ownership).

Customization Without Vendor Lock-In

Need a different connector or a new I/O config?

With open source designs, you can:

• Fork an existing layout
• Adapt firmware for your use case
• Maintain your own long-term software support

This is critical for products with long life cycles or regulatory constraints.

Strong Community and Ecosystem

Open boards like the BeagleBone, Pine64, and Libre Computer benefit from active developer communities. You get:

• Shared bug fixes and enhancements
• Tutorials, code samples, and overlays
• Long-tail support for old releases

If you need to port software or troubleshoot hardware, chances are someone has done it before — and shared the solution.

Common Use Cases for Open Source ARM Boards

Industrial IoT & Automation

Use open ARM motherboards to build:

• Field gateways with Modbus, CAN, RS485
• Touchscreen HMIs running Linux
• Smart meters or data loggers with secure boot

They provide long-term stability, real-time performance, and open control.

Robotics and Edge AI

Thanks to GPU/NPU integration and ROS support, open ARM boards are ideal for:

• Autonomous vehicles
• Vision-based pick-and-place robots
• AI-powered arms and kiosks

You can run inference engines locally without relying on the cloud — critical for low-latency decisions.

Education and STEM Learning

Open source hardware teaches:

• Circuit design and PCB layout
• Linux driver development
• Embedded programming with Python/C/C++

Many universities and makerspaces use boards like BeagleBone or Libre Computer for capstone projects.

Secure Embedded Systems

From banking terminals to health kiosks, transparency matters.

Open source boards let developers:

• Audit every line of firmware
• Control boot sequences and security keys
• Comply with strict cybersecurity standards

They’re often used in open government, blockchain nodes, and regulated environments.

Smart Terminals and Kiosks

Need to deploy Android-based signage or POS terminals?

Open ARM boards with touch and HDMI support are:

• Easy to skin and brand
• Compatible with most CMS platforms
• Remotely upgradable and secure

Pair them with a fanless design for 24/7 commercial-grade operation.
