## Overview

This repository is a KiCad design for the ATLAS PHat prototype: its central artifact is a board schematic and PCB, with separate schematic sheets named for power and device interfaces. The likely engineering workflow is to define circuit sections in the schematic sheets and realize them on the PCB. The tree supports those component identities, but no README or schematic excerpts were provided, so links between sheets and board artifacts are shown only as unverified; electrical connectivity and runtime behavior cannot be established here.
