Kicad for software developers
summary
Hands-on KiCad 5 tutorial that walks through drawing a complete schematic for a 24 V sprinkler relay controller with an ESP8266 Wi‑Fi switch and solar‑friendlier power conversion, using eeschema for symbols, annotation, ERC and footprint assignment, then pcbnew for two‑layer layout, zones, vias and 3D preview. It shows concrete design rules (0.15 mm trace, 0.6/0.3 mm vias), produces Gerber files and demonstrates uploading to JLCPCB for a $2 prototype plus shipping; the board is manufacturable and verifiable.
