The frustrating part of PCB work is rarely the circuit concept. It is the repetitive overhead: missing footprints, manual current calculations, and router guardrails that are easy to miss under schedule pressure.
On this relay board, CopperPilot handled the full workflow in KiCad: schematic capture, two custom footprints from measured geometry, a new 3D part model, and IPC-2221-based trace-width sizing for 10A relay-contact paths.
It then routed all 16 nets and finished with zero DRC errors, preserving a full decision trail so every step can be audited without reverse-engineering a black box.
