CAD (KiCad official)

  • Symbol: NRF52810-QFAA-T
  • Footprint: Package_DFN_QFN:QFN-48-1EP_6x6mm_P0.4mm_EP4.2x4.2mm
  • 3D model: QFN-48-EP(6x6), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.9 mm nominal QFN height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: nrf52810-qfaa-t-etched.step / nrf52810-qfaa-t-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); nrf52810-qfaa-t.step / nrf52810-qfaa-t.glb are the bare package body.
