Notes
- Datum: board centre, board bottom at 0, components on top. PCB 25.40 × 25.40 (1.0 × 1.0 in), square corners, 1.6 thick (standard; not stated in the board file).
- Four Ø3.30 holes for M3 or #4-40 at (±10.16, ±10.16): a 20.32 square, 2.54 from each edge.
- Two Qwiic (JST SH 4-pin side-entry) connectors, each 4.25 × 6.00 × 2.95, centred at x ±10.10 on the centre line, openings facing the ±x edges; top at 4.55 above the board bottom.
- Not modelled: the two 1 × 6 0.1 in header rows along the ±y edges (plated holes, no headers fitted) and the 3 × 3 × 1 ICM-20948 at the board centre.
- Dimensions are exact nominal (true size), no tolerance added.
