Licence and reuse
The project ships its own license terms rather than a standard SPDX license. Open the license file in the repository and read it before you reuse the files — custom hardware licenses often restrict commercial manufacture.
Opening it in ProtoFlow
The repository does not clearly state which EDA tool produced the files — check the repository contents before planning an import.
- 01 Select “Edit in ProtoFlow” for opening options. Download the source and open supported KiCad files in the app. Other EDA formats may need conversion.
- 02 Work in the imported local copy: rename nets, swap parts against live distributor stock, re-route, or strip it back to the sub-circuit you actually need.
- 03 Keep the original licence and credit hkzlab if you publish or sell what you build from it.
This page indexes a public repository. The design, the files and the copyright belong to hkzlab; ProtoFlow does not host, mirror or verify them. Details are read from GitHub and refreshed periodically — check the repository for the current state of the project.
