## CAD (KiCad official)

- Symbol: `HAL248RST`
- Footprint: `Package_TO_SOT_SMD:SOT-23-3`
- 3D model: TSOT-23-3L (KiCad packages3D, STEP)
- 3D model files: `hal248rst-etched.step` / `hal248rst-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `hal248rst.step` / `hal248rst.glb` are the bare package body.
