PCB ReTrace Demo: Turning traced nets into KiCad Schematics

Overview
A quick demo of the new "Schema ReTrace" feature in PCB ReTrace, a free, open-source, and entirely browser-based tool for documenting and reverse-engineering printed circuit boards.

In this video, we take a previously traced board (a UPS circuit) and use the new Schema builder to visually arrange the extracted components and nets. We also demonstrate fetching standard KiCad symbol libraries directly in the browser, swapping out generic components for standard schematic symbols, organizing the layout, and exporting the final result as a native KiCad .kicad_sch file.

Everything you see runs 100% locally in your web browser—no cloud uploads required!
