LitaElek20m 65.6ft 22AWG RGB LED Strip Extension Cable 4 Pin LED Tape Extension Cord Wire Extender Connector Connection Cable for SMD 5050 3528 2835 RGB LED Strip

I use this for it's designed use with LEDs, but it is also very useful for making leads for I2C devices and sensors to be used with electronics and Arduino, as these often have 4 connections.The cores themselves can just about be persuaded to crimp into Dupont connectors, but it's a very tight fit, and getting the shells on is hard, but it can be done.The insulation is very tough, like a harder version of PVC, and the cores difficult to separate without a sharp knife, a good thing.For the length you get, this is a pretty nice price and will last me quite a while.

Useful wire for model layouts.

Highly recommended

Working as expected. Thanks.

It's wire - it's 4 stranded - it's coloured! Brill!
