JST Connectors
From YourSpec Automotive Wiring Wiki
JST Connectors refers to a family of electrical connectors made by the Japanese company JST.
JST Connectors in their most-recognizable form are white plastic connector housings and headers on PCBs.
JST Connectors are usually described using the series, pin-to-pin pitch, wire count and gender. For example, a 3 pin female JST XH connector would be described as:
- JST XH 2.5mm 3-pin female
