📂 Folder Descriptions

/hardware/

Contains all electrical design files:

• schematics/: KiCad or EDA schematic files
• pcb/: PCB layout files
• bom/: Bill of Materials
• manufacturing/: Gerbers, pick-and-place, drill files
• simulations/: Simulation circuits (e.g. SPICE)

/mechanical/

Mechanical or enclosure design:

• enclosure/: STL/STEP files for 3D-printable parts
• cad/: Editable CAD models (FreeCAD, Fusion360)
• drawings/: 2D drawings for fabrication or documentation
• stl/: Final 3D-printable export files

/firmware/

Firmware source code:

• src/, include/, lib/: Microcontroller code and dependencies
• Example: PlatformIO, STM32Cube, Arduino, Zephyr

/software/

Optional software tools, GUI, or helper scripts:

• gui/: Any frontend or desktop apps
• scripts/: CLI or backend support tools

/docs/

Project documentation:

• overview.md, quickstart.md, photos, diagrams
• datasheets/: PDFs of important components

/tests/

Hardware and firmware testing:

• hardware/: Test jigs, test instructions
• firmware/: Unit and integration test code
• reports/: Test results, logs, and photos

/ci/

Automation and CI pipelines:

• GitHub Actions, GitLab CI, etc.

/tools/

Developer tools, flashing utilities, debug helpers

/certs/

Regulatory and certification documents (e.g., CE, FCC)

/manufacturing/

Everything needed for production:

• assembly/: Instructions for assembly/test stations
• fab/: Files needed by PCB fab houses

/meta/

Project metadata:

• b4l_manifest.json: Name, version, tags, license
• authors.md, changelog.md
