## Overall (mm)

| length | width | height |
|---|---|---|
| 20.32 | 20.32 | 1.6 |

**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

- Board 20.32 × 20.32 (0.8 × 0.8 in), 1.6 thick, square corners, centred.
- No mounting holes: the board mounts by its two 1×8 header rows.
- Sixteen Ø1.12 header holes, two rows of eight at 2.54 pitch, rows 15.24 apart (x = ±7.62 from centre, y = ±1.27 … ±8.89).
- Modelled: board outline and header holes. Not modelled: the low TB6612FNG IC on top. ROB-14450 is the same board with male headers soldered on.
- 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)

|---|---|---|---|---|
| Header rows | 2 × 8 holes, 2.54 pitch, rows 15.24 apart | 2.54 mm pin headers into a breadboard or female sockets | designed | all |
