CAD (KiCad official)

  • Symbol: FODM2701
  • Footprint: Package_SO:SOP-4_3.8x4.1mm_P2.54mm
  • 3D model: SOP-4-2.54mm (KiCad packages3D, STEP)
  • 3D model files: fodm2701-etched.step / fodm2701-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); fodm2701.step / fodm2701.glb are the bare package body.

Provenance
