footprints/ATTRIBUTION.md

# KiCad footprint attribution

The connector footprint files and their converted TSX geometry originate in the KiCad community libraries: USB3_A_Molex_48393-001, USB_C_Receptacle_Amphenol_12401548E4-2A, and SD_TE_2041021. The Coilcraft XxL4020 and CP_Elec_6.3x5.8 files are retained as land-pattern references.

Source collection: https://github.com/KiCad/kicad-footprints and the archived KiCad `.pretty` libraries. These library files retain CC-BY-SA 4.0 with the KiCad library exception. See LICENSE-KiCad.md.

Normalized copies change only legacy 3D-model `at` syntax to `offset`. The project's connector imports use the converted pad, drill, outline and courtyard geometry, with the unsupported pill `height` property removed and reference text replaced with the component's name. The authored custom QFN, Coilcraft and electrolytic footprint implementations require manufacturer review before fabrication.
