## Overview

This repository is an open-hardware design for a breadboard power-supply board, not a software runtime. Its user-facing workflow is to supply DC through a jack or USB-C, then use the board’s selectable power rails. The documented design covers the schematic and PCB, while production and reference files include manufacturing packages, BOMs, interactive BOMs, schematics, 3D models, and compliance documents. No source excerpts are available, so the graph shows only relationships stated in the README; it does not infer how output files were generated from the CAD designs.
