Notes
- Datum: board centre, component side up, board bottom at 0. PCB 60 × 40 × 1.6, corners R0.8, on Seeed's Grove 20 mm grid.
- Grove edge: five round ears Ø4.2 on the edge line, each with a Ø2.2 hole (table), and five Ø4.2 notches at (−20, +20), (+20, +20), (0, −20), (−30, −10), (+30, −10). The ears take the outline to 64.2 × 44.24.
- Above the board: Grove 4-pin 2.0 mm right-angle connector on the −x edge, 6.0 tall, opening toward −x; eight 2 × 3 2.54 mm servo headers (16 channels) in 4 columns × 2 rows at x ±10.29 and ±20.32, y ±13.97, 8.5 tall; 2-pin 5.0 mm servo-power screw terminal at the +x edge, 14.8 tall; two Ø6.3 electrolytic capacitors 5.4 tall.
- Component heights come from the footprint package names (not in the board file). Not modelled: the PCA9685 chip, SMD passives, test pads and solder jumpers.
- Dimensions are exact nominal (true size), no tolerance added.
