Molex KK 254 MX5264 2.54mm Connector Kit with 22AWG Pre-Crimped Cables

Molex KK 254 / MX5264 2.54mm Connector Kit with 22AWG Pre-Crimped Cables — Complete Assortment for Arduino, 3D Printers & Industrial PCB Wiring

The Molex KK 254 / MX5264 2.54mm connector kit with 22AWG pre-crimped cables is the all-in-one solution for Arduino builders, 3D printer enthusiasts, PC modders, and industrial PCB engineers who need a comprehensive assortment of genuine KK 254 / MX5264 connectors and pre-crimped cables in a single package. This kit includes male and female housings across multiple pin counts, along with 22AWG UL1007 pre-crimped cables — everything you need to build, repair, and prototype KK 254 wiring harnesses without ordering individual components.

The KK 254 / MX5264 2.54mm connector system is the industry standard for Arduino GPIO headers, PC fan connectors, 3D printer wiring, and general-purpose PCB connections — offering a positive-lock latch that prevents accidental disconnection, unlike standard DuPont friction-fit connectors. With genuine housings and factory pre-crimped cables, this kit ensures consistent, professional-quality connections every time.
