## Overall (mm)

| length | width | height |
|---|---|---|
| 54.0 | 54.0 | 16.5 |

**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: enclosure centre; back face at 0, screen face at 16.5.
- Enclosure 54.0 × 54.0 × 16.5; corners drawn square because the drawing does not dimension their radius.
- Four Ø3.2 holes in the back face on a 44.0 × 44.0 square, 5.0 from each edge. They are the M3 screws that hold the base and can be used to mount the unit; modelled 4.0 deep (depth not on the drawing).
- Side ports and screen are flush with the enclosure, so nothing protrudes beyond 54 × 54 × 16.5.
- Not modelled: USB-C, Grove Port A, power button and TF-card openings, the rear keyhole slot, the speaker grille and the rear boss and LED.
- Dimensions are exact nominal (true size), no tolerance added.
