## Overall (mm)

| length | width | height |
|---|---|---|
| 68.58 | 53.34 | 7.0 |

**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

- Exact nominal dimensions. Arduino UNO shield outline 68.58 × 53.34 × 1.6 mm with the UNO's two 2.54 × 2.54 chamfers on the +X edge; datum is the board centre, bottom on z=0.
- Three mounting holes Ø3.2 at (−19.05, +24.13), (+31.75, +8.89) and (−20.32, −24.13), i.e. UNO holes (15.24, 50.80), (66.04, 35.56) and (13.97, 2.54) from the UNO's lower-left corner. The fourth UNO hole is not drilled.
- Tallest parts: three Ø5.0 electrolytic capacitors, top 7.0 mm above the board bottom, at (+14.10, −4.95), (−20.57, −11.30) and (−26.92, +15.37).
- Not modelled: Arduino stacking headers, 3.5 mm terminal blocks and servo headers (all ship loose), ICs and small parts.

## 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 | 3 × Ø3.2 on the Arduino UNO hole positions; PCB 68.58 × 53.34 × 1.6 | M3 screws or standoffs, or the Arduino Uno below | designed | all |
| Arduino headers | UNO R3 shield header positions, 2.54 mm pitch | Arduino Uno R3 female headers via stacking headers | designed | all |

## Sizes

| hole | x mm | y mm | diameter mm |
|---|---|---|---|
| 1 | -19.05 | 24.13 | 3.2 |
| 2 | 31.75 | 8.89 | 3.2 |
| 3 | -20.32 | -24.13 | 3.2 |

## Questions

**How big is the Adafruit Motor Shield V2?**

68.58 × 53.34 mm (2.7 × 2.1 in), the Arduino UNO outline, 1.6 mm PCB; 7.0 mm tall at the capacitors without headers.

**Which mounting holes does the shield have?**

Three Ø3.2 holes on Arduino UNO positions (13.97, 2.54), (15.24, 50.80) and (66.04, 35.56); the hole at (66.04, 7.62) is not drilled.

**Does it fit an Arduino Uno enclosure?**

Yes: same outline and hole positions as the UNO; allow for the stacking headers and the terminal blocks above the board.
