What’s in the repository
- KiCad schematic and PCB layout source files
- Full revision history, so you can see how the board changed between versions
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
Select Edit in ProtoFlow for the available opening options. Download the source and open supported KiCad schematic or board files in the desktop app; check the project version and external libraries.
- 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 Fescron if you publish or sell what you build from it.
