## Notes

- SH is the 1.0 mm pitch connector on Pixhawk-class flight controllers (Qwiic/STEMMA QT use it too). Housing SHR-nnV-S (SHR-nnV-S-B with protrusions), 2 to 15 circuits plus 16 and 20 (protrusion type); headers SM..B-SRSS-TB (side entry). Pitch span of n circuits = 1.0 × (n − 1) mm.
- The housing width columns and drawing numbers are unlabeled in the text layer, so they are not 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.
- Existing KiCad-derived header bounding boxes for related JST series are on the JST connectors page.
