ZECTRIX / Zectrix Lab follows a staged open-development strategy. Firmware, drivers, interfaces, and printable enclosure resources that are ready for third-party development are published through public pages, while production firmware, cloud operations, and manufacturing materials are organized and released according to maturity. The links below are the current entry points. The license attached to each repository or model page defines its actual permitted use.
| Resource | Scope | Status | Access | License |
|---|---|---|---|---|
| NOTE4C four-color firmware source | NOTE4C · 400 × 300 four-color display | Public, under active organization | GitHub | MIT License; retain the original copyright and license notice |
| NOTE4 e-paper reference demo | NOTE4 · 400 × 300 black-and-white display | Public and independently buildable | GitHub | MIT License · Zectrix Lab |
| Open API and device interfaces | Devices running official firmware | Public | API documentation | Subject to the API documentation and service terms |
| AI Voice Sticky Note printable enclosure | Current public enclosure and print profile | Published on MakerWorld | MakerWorld model page | MakerWorld Standard Digital File License; not a software open-source license |
2bpmacheng2017 copyright notice. It originates from LazyYoun/youn-ink-fourcolor-firmware.Model warning: NOTE4C firmware must not be flashed to a black-and-white NOTE4. Before building or flashing, verify the model, flash capacity, partition table, and write offset, and back up the original 16 MiB flash. Public source code is not the complete delivery package for ZECTRIX commercial cloud services or production firmware.
maincomponents/zectrix_epd display driver, NOTE4 board adapters, demo UI, hardware self-tests, asset tools, and integration documentation.THIRD_PARTY_NOTICES.md in the repository for third-party font and component licenses.Scope: This is a hardware capability demo and driver reference for the black-and-white NOTE4. It is not the complete NOTE4 consumer firmware or cloud service, and it is not compatible with NOTE4C. Flashing replaces the firmware currently on the device; make a backup first.
License warning: Although the enclosure is publicly listed and has an access entry point, it is not open source under a conventional license such as MIT, GPL, or CERN-OHL. A firmware license does not automatically cover the enclosure files. Obtain separate written permission from Zectrix Lab before mass production, sale, republication, or creation of distributed derivatives.
The public documentation covers device discovery, screen-content delivery, to-do management, and related interfaces. Developers can use these interfaces to build desktop clients, automation scripts, content-delivery plugins, and third-party services.
Never commit API keys, device identifiers, or service credentials to a public repository. Technical access to an interface does not automatically grant commercial display or redistribution rights for third-party data.
Schematic PDFs, assembly references, and batch-specific materials may be requested from official support for qualified development needs. These references do not mean that a production BOM, supply-chain information, editable PCB project, or manufacturing authorization has been released.
These boundaries protect device security, user data, and reliable delivery. A public demo, API, or download page should not be interpreted as default authorization for the materials above.
The roadmap describes the current direction; it is not a fixed release schedule or a promise that every internal resource will be published. Actual releases may change according to hardware revisions, security risks, third-party licenses, and maintenance capacity.
Thank you to every developer contributing to the ZECTRIX / Zectrix Lab ecosystem.
