Disclaimer
Effective Date: September 29, 2026
All content published on this Website, including PCB design files, circuit schematics, hardware module descriptions, and related technical documentation, is primarily intended for personal DIY projects, educational purposes, and experimental reference by electronics enthusiasts. We also provide custom hardware design and development services.
1. Technical Information and Performance Disclaimer
Hardware specifications, test waveforms, circuit designs, and performance data published on this Website are based on testing conducted under specific laboratory conditions, unless otherwise stated.
A design may have the potential to support high-reliability applications. However, its suitability for any specific end product or operating environment must be independently evaluated and verified by the client. This includes compliance with applicable industry standards, local laws and regulations, safety certification requirements, and system-level reliability testing.
DIY circuit boards, modules, and related hardware products featured on this Website are intended for development, experimentation, and evaluation. Unless expressly stated otherwise, they should not be assumed to have obtained any mandatory industry certifications or safety approvals.
Actual performance may vary depending on components, assembly quality, operating conditions, integration methods, and other factors.
2. Electrical Safety and User Responsibility
Power supply circuits and other electronic hardware may present risks, including electric shock, overheating, fire, and damage to connected equipment or loads.
Anyone who solders, assembles, wires, powers on, tests, modifies, or otherwise uses these circuits or products is responsible for taking appropriate safety precautions and ensuring that the equipment is suitable for the intended application.
Improper assembly, wiring, testing, or operation may result in equipment damage, property loss, personal injury, or other consequences.
To the extent permitted by applicable law, users assume responsibility for risks arising from their own assembly, modification, installation, and use of DIY hardware products and circuit designs. Nothing in this Disclaimer excludes or limits liability that cannot lawfully be excluded or limited.
3. High-Reliability and Safety-Critical Applications
We may undertake hardware design projects for high-reliability or regulated applications, including automotive systems, energy storage equipment, medical-related devices, and life-support systems, subject to project-specific assessment and agreement.
If you intend to use our designs or services in these applications, you must disclose the intended use, applicable industry standards, regulatory requirements, certification requirements, and relevant operating conditions during the initial project discussions.
The parties must agree in a separate written project contract on the applicable design requirements, verification and testing plans, deliverables, and allocation of responsibilities.
Content displayed on this Website does not constitute a commitment to deliver a design suitable for any particular safety-critical application, nor does it guarantee regulatory compliance or certification.
Unless otherwise expressly agreed in writing and permitted by applicable law, the client is responsible for leading and coordinating final product certification, system-level safety verification, and compliance with the requirements applicable to the finished product.
4. Custom Hardware Development Services
All deliverables, project scope, acceptance criteria, timelines, fees, warranty obligations, and other contractual responsibilities relating to custom hardware development services are governed by the formal written agreement signed by the relevant parties.
Descriptions, project examples, technical specifications, and other information published on this Website are provided to demonstrate technical capabilities and previous work. They do not constitute a binding commitment regarding the scope, performance, delivery, or outcome of any future project.
If there is any inconsistency between information published on this Website and a signed project agreement, the applicable terms of the project agreement will govern, subject to applicable law.
5. DIY Products, Assembly, and Use
This Website may provide product descriptions, technical documentation, project information, and links to external purchasing channels.
Unless expressly stated otherwise, the Website does not directly handle product orders or payments. We are not responsible for losses resulting from user-performed soldering, assembly, wiring, debugging, installation, modification, or operation, except to the extent such responsibility cannot lawfully be excluded.
Before using any circuit or hardware product, users should review the relevant documentation, verify electrical compatibility, observe appropriate safety precautions, and conduct suitable testing under the intended operating conditions.
Users should not deploy experimental hardware in applications where a failure could cause serious injury, loss of life, or substantial property damage unless the design has undergone the necessary engineering review, validation, and approval for that application.
6. Accuracy and Suitability of Information
We make reasonable efforts to keep the technical articles, circuit designs, project documents, and other information on this Website accurate and up to date. However, we do not guarantee that all content is complete, error-free, or suitable for every application.
Technical documentation may contain errors, omissions, or information that becomes outdated over time. The suitability of any design must be assessed and validated against the actual operating conditions and requirements of the final product.
Users are responsible for independently reviewing, testing, and verifying any design or technical information before relying on it in a practical application.
7. Third-Party Advertising and Affiliate Links
We may introduce third-party advertising or affiliate marketing programs in the future. Such content may include advertisements, sponsored links, or affiliate links to third-party products and services.
Third-party advertisers and affiliate partners are responsible for their own advertising claims, products, services, and business practices. We do not guarantee the accuracy of third-party advertising content or the quality, safety, or suitability of advertised products.
Where required, we will identify advertising or affiliate relationships in accordance with applicable disclosure requirements. Any purchase made through a third-party link is subject to the relevant seller’s terms and policies.
8. Changes to Website Content
We reserve the right to update, revise, remove, or discontinue any project documentation, technical article, product description, or other content on this Website at any time, subject to applicable law.
We may make such changes without prior notice. We encourage visitors to check the relevant pages periodically for updated information.
