Add real FSC-BT1035 footprint, reconstructed from DigiRadio's EasyEDA project
Extracted 52 pad records + silkscreen geometry from the raw JSON-Lines document format inside manvalan/DigiRadio's fabricated EasyEDA Pro project (epro2kicad couldn't handle this project's newer multi-doc export format, so the relevant FOOTPRINT document was located and parsed directly). Pad size/pitch independently match the official FSC-BT1035 datasheet's mechanical spec exactly; pad numbering follows the same perimeter walk as the datasheet's own pin table, so pad N = pin N. The underlying component was originally a SnapEDA export for the mechanically-compatible FSC-BT806 (same 13x26.9mm 52-pad family package), relabeled BT1035 by the designer -- documented in README. Validated with kicad-cli fp export + visual SVG comparison against the datasheet's own footprint layout figure before import. No 3D model.

**No footprint or 3D model is included.** The datasheet's mechanical
|
||||
section (module 13 x 26.9 x 2.2mm, castellated LCC-52 package, 1.0mm pad
|
||||
pitch, antenna keep-out on one edge) has enough detail to build one, but
|
||||
extracting exact per-pad coordinates reliably from the PDF's dimensioned
|
||||
drawing (rather than a real coordinate table) was judged too
|
||||
error-prone to commit blind -- a wrong castellated-pad footprint could
|
||||
produce an unfabricatable board without anyone noticing until parts
|
||||
don't line up. A working footprint for this exact part does exist
|
||||
(fabricated, per the gerbers) in `manvalan/DigiRadio`'s EasyEDA project,
|
||||
but its pad geometry is embedded in EasyEDA's proprietary JSON format,
|
||||
which wasn't reverse-engineered here. Import a verified footprint (e.g.
|
||||
from a SnapEDA KiCad download, or by exporting the DigiRadio EasyEDA
|
||||
footprint to KiCad format) with `scripts/import_snapeda.py` or
|
||||
`scripts/add_component.py --name FSC-BT1035 --footprint ...` -- it will
|
||||
detect the existing symbol and only need the footprint/model added.
|
||||
`footprints/rf/FSC-BT1035.pretty/FSC-BT1035.kicad_mod` was reconstructed
|
||||
from the actual PCB footprint in `manvalan/DigiRadio`'s EasyEDA Pro
|
||||
project (a fabricated, gerber-verified design) by extracting the raw pad
|
||||
records from that project's internal document format (JSON-Lines with
|
||||
`PAD`/`POLY` records per document; the relevant footprint document was
|
||||
located, isolated, and parsed directly -- KiCad's own `epro2kicad`
|
||||
converter couldn't be used as-is, since this newer EasyEDA Pro export
|
||||
bundles all documents into one multi-record file rather than the
|
||||
per-document files it expects). Notably, that project's component was
|
||||
originally sourced from a SnapEDA export for the mechanically-compatible
|
||||
**FSC-BT806** (same manufacturer, same 13 x 26.9mm 52-pad castellated
|
||||
family package used across BT806/BT1026/BT1035/BT1038) and relabeled
|
||||
`FSC-BT1035` by the designer; the extracted pad size (1.6 x 0.6mm) and
|
||||
pitch (1.0mm) match the official FSC-BT1035 datasheet's own mechanical
|
||||
spec exactly, and the pad numbering follows a single clean perimeter
|
||||
walk (left column top-to-bottom, bottom row left-to-right, right column
|
||||
bottom-to-top) identical to the datasheet's own Table 3-2 pin order, so
|
||||
`pad N` = `pin N` throughout. Rounded body corners were simplified to

straight lines in the silkscreen (cosmetic only, no pad geometry

affected). No 3D model is included.
