JST Conector Cables

Note: Includes pre-wired male and female connector pigtails with stripped ends—simply solder, crimp, or wire-nut the bare leads together to complete your extension.

Extend and adapt your micro-electronics connections effortlessly with our JST 1.25mm Male to Female Connector Cables. Featuring an ultra-fine 1.25mm pin pitch (distance between pin centers), these miniature wire harnesses are engineered for high-density, weight-sensitive applications where standard 2.54mm Dupont wires or JST-XH connectors are far too bulky.

Equipped with a pre-crimped male plug on one end and a matching female socket on the other, these extensions allow you to bridge micro LiPo batteries, mini brushless motors, tiny speaker modules, analog sensors, and custom PCB headers directly to your main control board without cutting or soldering existing wiring.
