CAD (KiCad official)

  • Symbol: DST310S 32.768KHz
  • Footprint: Crystal:Crystal_SMD_3215-2Pin_3.2x1.5mm
  • 3D model: SMD3215-2P (KiCad packages3D, STEP)
  • 3D model files: dst310s-32-768khz-etched.step / dst310s-32-768khz-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dst310s-32-768khz.step / dst310s-32-768khz.glb are the bare package body.
