## Overall (mm)

| length | width | height |
|---|---|---|
| 20.32 | 12.7 | 1.57 |

**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 20.32 × 12.70 × 1.57 mm (0.8 × 0.5 in); datum is the board centre, bottom on z=0, long side along X.
- No mounting holes: the board mounts by its two 1 × 8 header rows.
- Sixteen header holes Ø1.02 on 2.54 mm pitch: rows at y = ±5.08 (10.16 apart, 1.27 mm from each long edge), holes at x = ±1.27, ±3.81, ±6.35, ±8.89.
- Components are low-profile and not modelled; headers ship loose and are not modelled. Corners modelled square.

## 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 holes | 2 × 8, Ø1.02, 2.54 pitch, rows 10.16 apart | 2.54 mm pin headers, breadboard or 16-pin 0.4 in socket | designed | all |

## Sizes

| row | y mm | holes x mm | diameter mm |
|---|---|---|---|
| A | -5.08 | −8.89 … +8.89 (8 × 2.54) | 1.02 |
| B | 5.08 | −8.89 … +8.89 (8 × 2.54) | 1.02 |
