# MuseAir
`index.circuit.tsx` is the real PCB design. The main **3D** tab displays `assembly.circuit.tsx`, which imports that same board and adds the sensor, holder, cables, display, speaker and enclosure as native assembly parts. The board uses its actual substrate, routed copper and imported component CAD—not an exported PCB mesh. PCB and schematic views retain the reviewed circuit.
The lid (`REMOVABLE_TOP_LID`), base (`ENCLOSURE_BASE`), button cap and other mechanical parts are independently hideable using the 3D viewer context menu. Open `index.circuit.tsx` for the bare circuit or `assembly.circuit.tsx` for the assembled device. Mechanical model assets are isolated in `assembly-assets/`; the assembly architecture and guarded build are documented in `mechanical/NATIVE-ASSEMBLY.md`.
The PCB model includes v0.5.7 ESP buck regulator. Manufacturing authority and qualification limitations are documented in the repository; physical fit and thermal testing remain outstanding.
