## Overall (mm)

| length | width | height |
|---|---|---|
| 85.0 | 56.0 | 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

- Datum: board centred on X and Y, bottom on z=0; the 2×20 GPIO header edge is −Y, the 8.4 V input / 5 V OUT / switch edge is +Y, the wide 23.5 mm margin is at −X.
- Board 85.00 × 56.00 mm, 1.6 mm thick, square corners (corner radius not dimensioned).
- Four Ø3.0 holes on a 58.00 × 49.00 mm pattern (Raspberry Pi HAT pattern): 23.50 from the −X edge, 3.50 from the +X and +Y edges.
- Not modelled: 2×18650 holder and cells, DC jack, power switch and GPIO header (their heights are not on the drawing).
- This is the 85 × 56 mm 2×18650 version; dimensions are exact nominal mm.

## Mating features (exact size; open press / slide / run / socket by your process clearance, leave designed and clamp as drawn)
