# Adafruit MPU-6050 6-DoF accelerometer & gyro (#3886, STEMMA QT): 25.4 × 17.78 mm board and 4 mounting holes

> What are the Adafruit MPU-6050 (product 3886) breakout dimensions and mounting-hole positions?

- Category: Electronic components › Modules, sensors & displays
- Kind: Modern device
- Basis: Adafruit's EagleCAD board file for the MPU-6050 STEMMA QT breakout, with connector height from the JST SH datasheet.

## Overall (mm)

| length | width | height |
|---|---|---|
| 25.4 | 17.78 | 4.55 |

**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

- This is Adafruit's own MPU-6050 board (product 3886). The generic GY-521 MPU-6050 board is about 21 × 16 mm with a different hole layout and does not share this footprint.
- Board 25.40 × 17.78 with R2.54 corners, centred, board bottom at 0. Board thickness 1.6 is assumed (Adafruit's board file does not state it); everything else is from the board file.
- Four plated Ø2.5 mounting holes at (±10.16, ±6.35) from the board centre: a 20.32 × 12.70 rectangle.
- Two STEMMA QT (JST SH 4-pin) connectors on the short edges, openings facing outward; 4.55 overall height.
- Not modelled: the two loose 1×6 0.1 in headers along the long edges and the 4 × 4 QFN chip.
- 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 × Ø2.5 on 20.32 × 12.70 | M2.5 or #2-56 screws and standoffs | designed | all |
| STEMMA QT connectors | 2 × JST SH 4-pin, 4.25 × 6.10, top 4.55, openings on both short edges | JST SH 4-pin cable plug; leave cable clearance past each short edge | designed | all |

## Sizes

| hole | x (mm) | y (mm) | diameter (mm) |
|---|---|---|---|
| 1 | -10.16 | -6.35 | 2.5 |
| 2 | +10.16 | -6.35 | 2.5 |
| 3 | -10.16 | +6.35 | 2.5 |
| 4 | +10.16 | +6.35 | 2.5 |

## Questions

**How big is the Adafruit MPU-6050 board?**

25.40 × 17.78 mm, 1.6 mm board (assumed), 4.55 mm tall over the STEMMA QT connectors.

**Where are its mounting holes?**

Four Ø2.5 holes on a 20.32 × 12.70 mm rectangle centred on the board.

**Does this fit a GY-521 board?**

No. The generic GY-521 is about 21 × 16 mm with a different hole layout; this page is Adafruit product 3886 only.
