3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
stm32f429igt6.step 2279 KB You want the bare part, or you mark your own boards.
stm32f429igt6-etched.step 11.4 MB You want the part with STM32F429IGT6 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 2837 faces against 2675 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: STMicroelectronics datasheet (102 pp, sha256 cfbe40d4b0d8b287, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
