Ideal for landing pages, saas. AI-ready template. Circuit boards were never meant to be beautiful. They were engineered — routed by necessity, constrained by physics. Copper traces follow the shortest viable path between components. Solder pads exist at precise intervals dictated by pin spacing. Every line serves a function. And yet, somewhere in the late '80s, designers started lifting these patterns out of their enclosures and plastering them across posters, album covers, and tech branding. The PCB became shorthand for 'this is the future.' It makes sense if you think about it. A circuit board is an engineering drawing that actually works. It's a blueprint that conducts electricity. There's something deeply satisfying about that overlap — form following function so literally that the function becomes the form. The green soldermask, the gold traces, the repetitive geometry of vias marching across a substrate. It reads as complexity, as intelligence, as something built with intention. The aesthetic peaked in the '90s cyberpunk era but never really left. It just got more refined. Today's PCB-inspired patterns strip away the literal green-and-gold and keep the topology — the branching paths, the nodes, the sense of interconnection. Less motherboard, more abstract network. - Density: 7/10 — Compact - Variance: 2/10 — Structured - Motion: 6/10 — Expressive - **Style:** Technical, Electronic, Structured, Precise - **Keywords:** Printed circuit board, copper traces, solder pads, IC chip outlines, electronic schematic, precision-engineered, technical, network-based - **Era:** Technical Electronic - **Light/Dark:** ✓ Full / ✓ Full ## Colors - **PCB Green** (#0F3B2C) — Primary surface or dominant color - **Copper Trace** (#D98C53) — Metallic accent, decorative detail - **Cream Label** (#EAD0AC) — Light surface, card backgrounds - **Dark Green** (#2D5C4E) — Dark surface, primary background - **Warm Brown** (#8B7355) — Extended palette, decorative use - **Gold Pin** (#C17817) — Premium accent, decorative highlights ## Typography - **Display / Hero:** System UI stack (-apple-system, sans-serif) — Weight 700, tight tracking, used for headline impact - **Body:** System UI stack (-apple-system, sans-serif) — Weight 400, 16px/1.6 line-height, max 72ch per line - **UI Labels / Captions:** System UI stack (-apple-system, sans-serif) — 0.875rem, weight 500, slight letter-spacing - **Monospace:** JetBrains Mono — Used for code, metadata, and technical values Scale: - Hero: clamp(2.5rem, 5vw, 4rem) - H1: 2.25rem - H2: 1.5rem - Body: 1rem / 1.6 - Small: 0.875rem ## Layout - **Grid:** CSS Grid primary.
