What Routing 314 Nets Taught Me About AI-Assisted PCB Design
Part three of a series on designing an Arduino Giga R1 level-shifter shield with Claude Code and open-source EDA tools. Covers the v0.4 respin: what Claude Code actually helped with, what it didn't, and what six hours of Freerouting clearance debugging revealed about the limits of LLM-assisted hardware design.
