Licence and reuse
Released under Apache-2.0, one of the permissive licenses. You can fork the design, change it, manufacture it and sell the result, provided you keep the original copyright and license notice with the files.
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 NationalAssociationOfRealtors 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 NationalAssociationOfRealtors; 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.
