From the project

30-Days-PCB-Design-Challenge

A self-directed challenge to design, document, and release one original PCB per day for 30 consecutive days using KiCad 8. Each board lives in its own folder with complete hardware source files, gerbers, a bill of materials, and a standalone README covering the design rationale, schematic walkthrough, layout decisions, and common troubleshooting for that specific circuit.
