Premium Jumper Wire 60-Piece 6-Color Assortment M-F 2".

Wires with Pre-crimped Terminals 60-Piece 6-Color Assortment M-F 2".

Our popular premium jumper wires and wires with pre-crimped terminals are a convenient way to make quick, neat connections to 0.1″ (2.54 mm) connectors and solderless breadboards, and they are now available in shorter 1″ and 2″ lengths. Each new length is available in three gender combinations (female-female, male-female, and male-male) and seven color combinations:

  • black 10-pack
  • red 10-pack
  • yellow 10-pack
  • green 10-pack
  • blue 10-pack
  • white 10-pack
  • multi-color 60-pack (10 each of all six colors)

Our wires with pre-crimped terminals work with our 0.1″ crimp connector housings to make custom cables with the pin arrangement of your choosing. You can easily make cable harnesses or assemblies that branch from one connector on one side to multiple connectors on the other, and you can also cut off one pre-crimped end and solder the wires directly to components to make swapping connections easy:

The premium jumper wires are just wires with pre-crimped terminals that have 1×1 crimp connector housings already installed over the crimp pins.

You can use the following selection boxes to get to a specific pack of premium jumper wires:

New track sets and colorful Zumo sprockets

Pololu 22T Track Set – Red.

We have replaced our original Pololu track sets with new versions featuring our newer style of spoked Zumo sprockets. The sprockets are available in three colors, and like our original sets, we have two different track lengths to choose from:

Each track is made of a single piece of flexible silicone, and the drive sprockets are designed to work with 3mm D-shafts, such as those on our micro metal gearmotors and most of our mini plastic gearmotors.

Additionally, we are offering sprockets by themselves (without tracks or fasteners) for use as replacements for the black sprockets included with our Zumo robots: you can use the red sprockets to add a splash of color, and you can use the white sprockets for painting (or just leave them white!).
