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

Drawn at the exact size. Open press, slide, run and socket features by your process's clearance (tolerances by process); leave designed gaps and clamp fits as drawn.
