Licence and reuse
No license is declared on the repository. Publishing files publicly is not the same as granting permission to reuse them, so ask the author before you build on this design.
Opening it in ProtoFlow
The design was drawn in Altium Designer. Altium projects need converting before they open in KiCad-compatible tools, so expect to check footprints and layer mapping after any 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 4pplet 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 4pplet; 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.
