CAD (KiCad official)

  • Symbol: PCA9534APWR
  • Footprint: Package_SO:TSSOP-16_4.4x5mm_P0.65mm
  • 3D model: TSSOP-16 (KiCad packages3D, STEP)
  • 3D model files: pca9534apwr-etched.step / pca9534apwr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pca9534apwr.step / pca9534apwr.glb are the bare package body.
