## Overall (mm)

| length | width | height |
|---|---|---|
| 69.14 | 25.4 | 4.8 |

**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. PCB 25.40 × 62.87 × 1.60 mm, square corners; datum is the lower-left PCB corner at (0, 0), bottom on z=0, USB-C end at y=0.
- No mounting holes: the board is held by its two 2 × 22 header rows (2.54 mm pitch) or in a breadboard.
- ESP32-S3-WROOM-1 module 18.00 × 25.50 × 3.10 mm at x 3.75–21.75, y 43.64–69.14: the antenna end overhangs the board edge by 6.27 mm (overall length 69.14).
- Two USB-C receptacles 8.20 mm wide, 3.20 mm tall, at x 1.90–10.10 and 15.30–23.50, y 1.03–6.30.
- Header pins project about 6 mm below the board: leave that clearance underneath. Not modelled: pins, buttons, LED 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 |
|---|---|---|---|---|
| header rows | 2 × 22 pins, 2.54 pitch, rows 22.86 apart, 6 below the board | breadboard or 2.54 mm female headers | designed | all |
| USB-C ports | 2 × 8.20 wide, top 4.8 above board bottom, at x 1.90–10.10 and 15.30–23.50 | USB-C openings in the case end wall | designed | all |
| module antenna overhang | 6.27 past the board edge, 18.00 wide, 3.10 tall | keep-out for antenna (no metal around it) | designed | all |

## Sizes

| feature | x mm | y mm | top z mm |
