Small JST Connectors

Courtesy of RCG user jj604, here's a nice thread that clears up some of the confusion around small JST connectors.  Here's an extract, but lots of interesting details at the link so check it out!

  • JST-XH is 2.5mm pin spacing (same as 0.1inch for all practical purposes)
    Not micro size but very common. Used in most balance plugs on LiPos and is the "standard" header spacing in many electronic components including PCs. The standard Futaba/JR style servo plugs are this spacing.
  • JST- ZH is 1.5mm pin spacing
    Used in the Spektrum AR 6300 system and a compatible DSM2 Rx from DelTang (DelTangs are available with all 3 connectors).
  • Molex PicoBlade is 1.25mm pin spacing.
    Used in Futaba, FlyDream, Walkera and the new Hobby King Micro (DSM2) 2.4G systems. The HobbyKing 1.7 and 2.2g Servos have this connector. The 2 pin version is used on the PZ bricks as a battery connector.
  • JST-SH is 1.0mm pin spacing.
    Used for servo connection in Spektrum AR6400 "Brick" and the HobbyKing SuperMicro (not DSM2) systems. Most linear servos have this connector.
