1″ (2.5 cm) and 2″ (5 cm) premium jumper wires and wires with pre-crimped terminals
|
|
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:
- 22T tracks with black sprockets
- 22T tracks with red sprockets
- 22T tracks with white sprockets
- 30T tracks with black sprockets
- 30T tracks with red sprockets
- 30T tracks with white sprockets
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!).

Addressable through-hole RGB LEDs are back
We’re happy to announce that our previously discontinued addressable through-hole RGB LEDs are once again part of our catalog and in stock! While these might look like ordinary RGB LEDs, each one contains its own integrated WS2811 LED driver that lets you chain them together and individually control them all with a single digital output from a microcontroller. The interface is very similar to that of our SK6812-based LED strips, so there is a variety of sample code available for the Arduino, AVR, and mbed microcontroller platforms.
The LEDs are available in two sizes: 5 mm and 8 mm.
Two different sizes of addressable RGB LED. From left to right, their diameters are: 5 mm (#2535) and 8 mm (#2536). |

New 5V step-up/step-down voltage regulator S9V11F5
Our newest step-up/step-down voltage regulator, the S9V11F5, takes input voltages between 2 V and 16 V and increases or decreases that voltage as necessary to produce a fixed 5 V output with a typical efficiency of over 90%. (Note that it requires a minimum of 3 V to start up, but it can operate down to 2 V once it is running.) It can temporarily deliver peaks of around 2 A, and the maximum continuous output current depends on the input voltage as shown in the graph below:
The ability to raise or lower the input voltage makes this regulator especially well suited for battery-powered applications where the nominal battery voltage is close 5 V, such as when using four NiMH cells, since the battery voltage transitions from above 5V to below as the battery discharges. The wide input voltage range is also great for applications where you want a lot of flexibility in power supply choice or for systems powered by alternative energy sources like solar or wind, where the output voltage can vary a lot.
With a wider input voltage range and its ability to deliver more current, the S9V11F5 is a higher-performance alternative to our popular S7V7F5 buck-boost regulator, all while being even smaller in size thanks to its double-sided assembly.
For more information on this regulator, visit the S9V11F5 product page, and for other regulator options, you can take a look at our full selection of step-up/step-down regulators, step-up voltage regulators, and step-down voltage regulators.
New 20D mm metal gearmotors
Our vast assortment of metal gearmotors has gotten even bigger! With over 100 micro metal gearmotor options and nearly 100 25D mm metal gearmotor versions to choose from, the next step seemed clear: expand our offering of 20D mm metal gearmotors, which fit nicely between the smaller micro metal gearmotors and larger 25D mm metal gearmotors. We have replaced our initial four 20D mm options with twelve entirely new gear ratios that feature more efficient gearboxes and much longer output shafts.
|
|
The motor portion is unchanged, and we now also offer versions with an extended motor shaft that rotates at the same speed as the input to the gearbox and can be used to add an encoder, such as our new magnetic encoder for 20D mm metal gearmotors, for closed-loop speed or position control.

The table below shows our current offering of 20D mm metal gearmotors:

We also have 12V versions on the way, so stay tuned for more information!
