# Arduino UNO Q (ABX00162 / ABX00173): board outline, 4 mounting holes and header positions

> What are the Arduino UNO Q dimensions and mounting-hole positions?

- Category: Electronic components › Microcontroller boards
- Kind: Modern device
- Basis: Arduino UNO Q datasheet ABX00162-ABX00173 (Mechanical Information), with the UNO hole and outline coordinates from the Arduino UNO R4 WiFi datasheet ABX00087.

## Overall (mm)

| length | width | height |
|---|---|---|
| 68.58 | 53.34 | 10.1 |

**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: lower-left corner of the board (USB-C edge on the left, power/analog header edge at the bottom), board bottom at 0.
- Standard UNO outline 68.58 × 53.34, 1.6 thick, with the stepped edge opposite the USB-C port.
- Four Ø3.2 mounting holes at the UNO positions (table); same pattern as the UNO R3 and R4.
- Header tops 8.5 above the board top (10.1 overall). Digital header along the top edge, power/analog header along the bottom edge, each 1.3 in from the edge.
- Modelled: outline, holes and header rows. Not modelled: USB-C, Qwiic connector, LED matrix and the bottom-side high-density connectors; leave 2 mm clear under the board.
- All dimensions are exact nominal millimetres, true size, with 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 × Ø3.2 at the UNO pattern | M3 standoffs or screws in a case or base plate | designed | all |
| Shield headers | 2.54 pitch female headers, tops 8.5 above the board | UNO-format shields and 2.54 mm header pins | designed | all |

## Sizes

| hole | x (mm) | y (mm) | diameter (mm) |
|---|---|---|---|
| 1 | 13.97 | 2.54 | 3.2 |
| 2 | 15.24 | 50.80 | 3.2 |
| 3 | 66.04 | 7.62 | 3.2 |
| 4 | 66.04 | 35.56 | 3.2 |

## Questions

**How big is the Arduino UNO Q?**

68.58 × 53.34 mm, the standard UNO size; 10.1 mm tall to the header tops with a 1.6 mm board.

**Does the UNO Q use the UNO R3 hole pattern?**

Yes: four Ø3.2 holes at (13.97, 2.54), (15.24, 50.80), (66.04, 7.62) and (66.04, 35.56) mm from the lower-left corner.

**How much room is under the UNO Q?**

Bottom-side connectors stay under 2 mm, so keep at least 2 mm clear under the board.
