From the project
KiCad protected buck converter with Python-based automated hardware validation, fault injection, and CI reporting
A portfolio project combining a protected 5 V buck-converter PCB with a Python automated validation bench. It demonstrates PCB design, instrument automation, fault injection, safety interlocks, data logging, and CI-style reporting—the day-to-day concerns of hardware validation and systems-integration engineering.
The editable source is hardware/protectedbuck.kicadsch; its generated PDF is included for design review. KiCad 10.0.6 reports zero ERC errors and zero ERC warnings, and the automated parity check matches all 88 schematic pins to 88 PCB pads.
