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. Mating features
- length
- 50.8 mm
- width
- 22.86 mm
- height
- 1.6 mm
Notes
- Exact nominal dimensions. PCB 22.86 × 50.80 mm (0.9 × 2.0 in), 1.6 mm; datum is the board centre, bottom on z=0.
- Four mounting holes Ø2.54 (0.1 in) at (±8.89, ±22.86): a 17.78 × 45.72 mm (0.7 × 1.8 in) pattern, 2.54 mm in from every edge.
- Header rows: two single rows of 2.54 mm pitch along the long edges, 20.32 mm (0.8 in) apart, 16 pins on one side and 12 on the other.
- Modelled: outline and holes. Not modelled: header pins, radio module, USB connector and U.FL connector (not dimensioned on the datasheet); corners modelled square.
