- Symbol: `SY6915RBC`
- Footprint: `Package_DFN_QFN:QFN-20-1EP_3.5x3.5mm_P0.5mm_EP2x2mm`
- 3D model: VQFN-20-EP(3.5x3.5), 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: `sy6915rbc-etched.step` / `sy6915rbc-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sy6915rbc.step` / `sy6915rbc.glb` are the bare package body.
