## Overall (mm)

| length | width | height |
|---|---|---|
| 65.0 | 56.5 | 18.52 |

**Exact dimensions.** Every file is drawn at true size with no tolerance added. The holes and pins that meet another part are listed below under Mating features, with the fit each joint needs; open those by your process's clearance before making the part.

## Notes

- Datum: board centre; +y is the 40-pin header edge. The bottom of the 40-pin socket is at 0, the board spans 8.51 to 10.05 (1.54 thick).
- Board 65.00 × 56.50 with R3.0 corners. Four Ø2.70 holes on the 58.0 × 49.0 Raspberry Pi HAT pattern (table).
- 2 × 20 stacking socket under the board (51.30 × 4.96, 8.51 deep below the board); the pin tails rise 8.47 above the board top, at 2.54 pitch on rows y +22.98 and +25.52.
- On top: two Qwiic (JST SH 4-pin) connectors 4.32 tall, three DIP switches 2.52 tall and the Notecard M.2 retaining standoff Ø5.10 × 2.50. Board cut-outs: a 5.0 × 17.0 notch in the −x edge and a 2.0 × 19.0 slot at x +12.50.
- Not modelled: the Notecard M.2 Key E socket, micro-USB, nano-SIM holder, u.FL connectors, the Notecard itself and small passives.
- Dimensions are exact nominal (true size), no tolerance added.

## Mating features (exact size; open press / slide / run / socket by your process clearance, leave designed and clamp as drawn)

| feature | exact | mates with | fit | files |
|---|---|---|---|---|
| mounting holes | 4 × Ø2.70 on 58.0 × 49.0 | M2.5 standoffs to a Raspberry Pi | designed | all |
| 40-pin stacking socket | 2 × 20 at 2.54 pitch, 51.30 × 4.96 | Raspberry Pi GPIO header pins | socket | all |
| Qwiic connectors | JST SH 4-pin, 1.0 pitch | Qwiic / STEMMA QT cables | socket | all |

## Sizes

| hole | x (mm) | y (mm) | Ø (mm) |
|---|---|---|---|
| 1 | −29.00 | +24.25 | 2.70 |
| 2 | +29.00 | +24.25 | 2.70 |
| 3 | −29.00 | −24.75 | 2.70 |
| 4 | +29.00 | −24.75 | 2.70 |
