Licence and reuse
Released under GPL-3.0, a copyleft license. You are free to fork and modify the design, but anything you distribute that is derived from it has to be published under the same terms — worth checking before it goes into a closed product.
Opening it in ProtoFlow
The design was drawn in EAGLE. EAGLE schematic and board files convert into KiCad format, which is the path to take if you want to carry this design into ProtoFlow.
- 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 ZakKemble 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 ZakKemble; 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.
