Open-source hardware can speed product development by letting a team start from reusable designs, editable source files, working development platforms, and shared documentation instead of building every circuit or mechanical element from scratch. The greatest gains are usually in exploration and prototyping; a product still needs engineering for cost, reliability, safety, manufacturing, supply, and legal compliance before it is ready to sell.
What counts as open-source hardware?
The Open Source Hardware Association (OSHWA) defines it this way: “Open source hardware is hardware whose design is made publicly available so that anyone can study, modify, distribute, make, and sell the design or hardware based on that design.”
In practice, the important test is whether the design’s preferred editable source files are available—not just photos, a rendered PDF, or a compiled file that cannot reasonably be changed. For an electronic product, that usually means original schematics and PCB layout files. For a mechanical product, it means the original CAD files. Documentation, a bill of materials (BOM), and build or assembly information can also be essential to understanding and reproducing a design.
A project may combine hardware, firmware, documentation, and third-party libraries governed by different licenses. Check each component rather than assuming that one license covers everything.

How can open hardware shorten development?
Reuse known building blocks
A development board or reference design can provide a working controller, interfaces, and documentation early in a project. An Arduino-compatible development board, for example, can help a team test whether a sensor, control loop, or user interaction works before committing to a custom circuit board. Reusing a known design can also avoid recreating standard circuitry.
Make review and iteration easier
When schematics, CAD, BOMs, and revision history are available, engineers, prospective suppliers, and users can inspect the design directly. Teams can build several iterations using readily available components and standard processes, then share editable files with colleagues or manufacturing partners. Public issue histories and community feedback may reveal integration problems earlier, though a project still needs someone to review proposed changes and control which revisions are accepted.

Keep design knowledge transferable
Editable source files are useful beyond the first prototype. A new team member or manufacturing partner can work from the design itself rather than trying to infer it from a finished device or static export. This can make handoffs and modifications more direct.
These are ways to reduce friction, not a guarantee of a particular schedule or cost saving. OSHWA and the other sources cited here do not establish a universal percentage or number of days saved. Any numeric claim would need to identify the project, its comparison baseline, and the year measured.

Which approach should you use: a development board, reference design, or custom board?
| Approach | Best fit | What it makes easier | What to account for before production |
|---|---|---|---|
| General-purpose development board | Early experiments and quick proof-of-concept builds | Getting a controller and common interfaces working without first designing a complete board | Whether the board’s cost, power use, size, reliability, and design suit the finished product; a production design may need to replace it |
| Open reference design | Adapting an existing circuit or mechanical design to a product’s requirements | Inspecting and editing the design rather than recreating it from a description | Whether the source files, documentation, components, and license are suitable for your intended changes and distribution |
| Custom production design | A product whose volume, form, power, reliability, or manufacturing constraints demand a tailored design | Designing around product-specific constraints | More design, verification, manufacturing, and supply-chain work than simply using a prototype platform |
The right starting point depends on what you need to learn. Use a board to test an idea quickly; use an editable reference design when adapting a known circuit or mechanism is central; plan for a custom design when the prototype platform does not meet the product’s production constraints. A prototype that works is evidence about the concept, not proof that its hardware is ready for launch.
How to use open hardware in a product-development workflow
- Define the audience and purpose. Decide who the design is for, why you want to open it, and what outcome you expect. Google’s Open Source guidance recommends making those decisions early.
- Choose a starting platform and check licenses. Identify the licenses for the hardware design, firmware, documentation, and third-party libraries. Confirm that their terms fit the changes you plan to make and how you expect to distribute the result.
- Prototype from editable files. Work from the schematics, board layout, CAD, and BOM where available. Record revisions and known limitations so the prototype can be reproduced and assessed.
- Decide what will be open. Identify which parts of your design you will publish and provide the preferred source formats, not only exported files. State the license and attribution requirements clearly.
- Engineer for the intended product. Check electrical, mechanical, thermal, safety, and manufacturing requirements. Replace general-purpose parts where the design needs different cost, power, reliability, certification, or manufacturability characteristics.
- Separate design rights from branding. Follow the relevant license and attribution terms, and keep your product’s branding distinct from upstream trademarks.
- Prepare for distribution. Before selling, provide the source and compliance information required by the license. Use version identifiers that connect physical units to the design releases they were built from.
Which hardware license should you choose?
Commercial reuse is compatible with open-source hardware, but the project must meet the applicable license conditions. The right choice depends on how you want others to be able to reuse and share modifications. Hardware-specific terms matter; do not assume a software license automatically addresses every hardware-design obligation.

CERN’s Open Hardware Licence, version 2, has three variants:
- CERN-OHL-S (strongly reciprocal): for projects that want stronger sharing obligations for derivatives.
- CERN-OHL-W (weakly reciprocal): for a weaker form of reciprocity.
- CERN-OHL-P (permissive): for a more permissive approach to derivatives.
CERN describes the OHL as a legal tool intended to promote collaboration and support the freedom to use, study, modify, share, and distribute hardware designs and products based on them. Read the specific license terms before choosing a variant; the labels alone are not a substitute for checking the obligations that apply to your design and distribution model.

OSHWA’s licensing guidance, updated in 2023, asks project owners to consider whether original design files are linked, which portions are open, and whether an open-source license is attached. Those points are also useful checks for anyone evaluating whether a design is genuinely reusable.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Can you sell a product based on Arduino hardware?
Arduino’s official guidance says products based on Arduino hardware can be distributed commercially when the applicable open-source licenses are followed. For a derived board, Arduino says the full BOM and CAD files must be made public under the applicable open license. Its trademark is separate from the design rights: you cannot use Arduino branding in a way that suggests the product is official or approved. Use an exact Arduino product name only where Arduino’s trademark policy allows it.
That distinction is broadly important in open hardware: permission to use or modify a design does not by itself grant permission to use the original maker’s name, logo, or product branding. Check both the design license and any relevant trademark policy before naming or marketing a product.
What still needs work before an open-hardware prototype can ship?
Open files and community knowledge can accelerate discovery, but they do not replace product engineering. Before launch, a team needs to assess the design against its actual production requirements.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problems- Manufacturability: Confirm that the design and assembly process are practical for the intended production method and volume.
- Component and supply risk: Check component availability and plan for supply changes rather than assuming prototype parts will remain suitable.
- Performance and reliability: Verify electrical, mechanical, and thermal behavior under the conditions the product must handle.
- Safety and certification: Determine which requirements apply to the product and complete the necessary checks; an open design is not itself a certification.
- Release and license compliance: Track versions, preserve required attribution, and provide source files and other compliance information promised by the applicable license.
Plan for extra design work when a general-purpose board is only a convenient way to test the idea. Moving to a production design may require replacing that board and revisiting cost, power, reliability, certification, and manufacturing assumptions.
