## CAD (KiCad official)

- Symbol: `RS724XQ`
- Footprint: `Package_SO:TSSOP-14_4.4x5mm_P0.65mm`
- 3D model: TSSOP-14 (KiCad packages3D, STEP)
- 3D model files: `rs724xq-etched.step` / `rs724xq-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `rs724xq.step` / `rs724xq.glb` are the bare package body.
