JST Is Not A Connector
We can simplify to “JST connector” when chit-chatting about projects. But when it comes to actual hardware specification, that’s not good enough. Which JST connector?
simple two pin wire-to-wire connector is probably the RCY series.
pitch: the distance between pins.
We start with the JST XH series. Its pitch of 2.5 mm is effectively identical to the 0.1″ pitch commonly found on prototyping breadboards. After the XH series, the pin pitch gets narrower, the wires get thinner, and the connectors are more fragile through PH (2.0 mm), ZH (1.5 mm), GH (1.25 mm), and SH (1.0 mm). The SH series are so small that JST specified optional protrusions to give us something to hold
keep in mind the possibility that it might not be a JST connector at all.
The Molex PicoBlade is a 1.25 mm pitch connector frequently confused with JST GH in the same pitch.
gain experience with connectors, we’ll make better guesses based on context
backyard-friendly hobby aircraft ecosystem (airplane, helicopter, and multi-rotor) uses many connectors designed by JST with Molex as a smaller player. The situation is reversed in PC components where Molex designed most of the connectors in that ecosystem.
