Notes
- Datum: board centred on X and Y, bottom on z=0; +Y is the screw-terminal edge, −Y the 6-pin header edge.
- Board 25.40 × 20.32 × 1.6 mm with R2.54 corners.
- Four Ø2.50 holes at (±10.16, ±7.62): a 20.32 × 15.24 mm pattern.
- Two side-entry JST SH 4-pin STEMMA QT connectors, 4.94 × 6.00 × 2.96, at x=±7.70..±12.64, centred in Y; overall height 4.56.
- Not modelled: the 1×6 header and 2-pin 3.5 mm terminal block (ship unsoldered). The original non-STEMMA board (25.40 × 22.24) is a different part.
- Exact nominal mm.
