Notes
- Datum: lower-left PCB corner (pin row along the left edge), board bottom at 0. PCB 22.10 × 19.94 × 1.68.
- Two Ø3.30 mounting holes, diagonal pair at (2.54, 17.40) and (19.56, 4.45).
- Transducer Ø15.24 centred at (11.05, 10.85), its face 15.60 above the board bottom (13.92 above the board top).
- Not modelled: the 7-pin 0.1 in header and its pins (they point down about 9.5, so keep 10 clear under the board) and small components.
- All dimensions are exact nominal millimetres, true size, with no tolerance added.
