Materials and finish

As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).

Part Material Colour / plating Datasheet says Page
contacts tin configurations, including indium tin oxide (ITO) sensor grids. The PTC requires one pin per X-line and one pin per Y-line. 382

CAD (KiCad official)

  • Symbol: ATTINY814-SSN
  • Footprint: Package_SO:SOIC-14_3.9x8.7mm_P1.27mm
  • 3D model: SOIC-14 (KiCad packages3D, STEP)
  • 3D model files: attiny814-ssn-etched.step / attiny814-ssn-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); attiny814-ssn.step / attiny814-ssn.glb are the bare package body.

Provenance
