Video tutorial on designing a 4-layer embedded PCB in KiCad 6.0. This includes an overview of basic PCB principles, component selection, schematic design, layout, routing, and ordering the fully assembled from JLCPCB. The video is accompanied by a GitHub repository that includes the KiCad 6.0 design files, exported manufacturing files (Gerber, NC Drill, BOM, and Component Placement), and basic firmware.
