## Notes

- GH is the 1.25 mm pitch latching connector on flight controllers, GPS modules and Pi cameras. Housing GHR-nnV-S, 2 to 15 circuits listed. Pitch span of n circuits = 1.25 × (n − 1) mm.
- Ratings, wire range and drawing dimensions were not available in a readable form from the sources reached, so none are published. No file: the datasheet drawing prints its dimensions as bare numbers without naming the feature each one measures, so no outline or cutout is drawn from them.
- Bounding boxes of KiCad-derived GH headers (2 to 6 circuits) are on the JST connectors page.
