CAD (KiCad official)

  • Symbol: RPI-243C1
  • Footprint: Package_DIP:DIP-4_W7.62mm
  • 3D model: DIP-4 (KiCad packages3D, STEP)
  • 3D model files: rpi-243c1-etched.step / rpi-243c1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rpi-243c1.step / rpi-243c1.glb are the bare package body.
