CAD (KiCad official)

  • Symbol: B3B-XH-2
  • Footprint: Connector_JST:JST_XH_B3B-XH-A_1x03_P2.50mm_Vertical
  • 3D model: JST_XH_B3B-XH-A_1x03_P2.50mm_Vertical (KiCad packages3D, STEP)
  • 3D model files: b3b-xh-2-etched.step / b3b-xh-2-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); b3b-xh-2.step / b3b-xh-2.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: JST datasheet (5 pp, sha256 ``, retrieved 2026-11-06, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins, primary connector numbering (convention), consensus off (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
