We are excited to introduce new versions of our high-power micro metal gearmotors with long-life carbon brushes in place of the standard precious metal brushes:
Micro metal gearmotor HPCB long-life carbon brushes (left) next to micro metal gearmotor HP precious metal brushes (right).
So far, we only offer these on motors with HP windings, so the brushes being a lot more robust can just move the failure point if you try to push the motors too hard. However, if you use them at around 6 V and keep the continuous load under around 20% of the stall torque, the carbon brushes allow the HPCB motors to last several times longer than HP versions with precious metal brushes.
With the addition of this new HPCB motor variant in ten different gear ratios (10:1 through 1000:1), our selection of popular micro metal gearmotors now spans more than fifty options, giving you control over the motor winding, gearbox, and shaft arrangement:

Make your next project more colorful with our new red, white, blue, and yellow breakaway male header strips. You can use them to add some personal flair to an otherwise boring PCB, or you can use them to color-code connections, like on this custom-assembled 24-channel Mini Maestro:
Like our venerable black breakaway male header strip, these strips are 40 pins long, but they can easily be cut or broken into smaller strips that work with standard 0.1″-pitch through-holes, female connectors, and breadboards.
We are particularly excited about the 3×40 right angle header because it can be used with the partial kit versions of our Maestro servo controllers to make low-profile modules where the servos plug in from the side rather than the top.
We now have 40mm-diameter wheels (available in black, red, and white) in the same thin style as our 32×7 mm wheels, which help fill the void between those and the 60×8 mm wheels that were previously our next size up.
Black Pololu wheels with 90, 80, 70, 60, 40, and 32 mm diameters (other colors available).

A customer of ours who is a software engineer in Seattle made this detailed video showing how to assemble the new Zumo 32U4 robot kit. Thanks for sharing it with us, Jamie!
We are now offering Sharp’s GP2Y0A60SZLF analog distance sensor by itself. This is a great sensor with a wide 4″ to 60″ (10 cm to 150 cm) detection range and a high update rate of 60 Hz, but it requires additional components to use and has a non-standard 1.5 mm pitch. You can use this sensor with our compact carrier boards to make a complete sensor module, or you can get our carrier boards with the GP2Y0A60SZLF already installed.
For more information, see the GP2Y0A60SZLF product page.
PeterPan, an active member of our forum, recently started a thread asking other Wixel users to push for us to get Wixels FCC certified. The Wixel is getting to be one of our older products, so it is due for some updates, too (e.g., our new USB products have moved on to Micro-B connectors). We realize many of our customers do not necessarily want to publicly discuss their projects, so if you do not feel like participating in the forum thread, please feel free to contact us directly about your thoughts on FCC certification and other ways you would like to see the Wixel improved.
Tomorrow is Arduino Day, and we are joining in on the fun by offering big discounts on many of our Arduino-related products, including our A-Star programmable controllers and Arduino shields. The sale has already started, and it will run through the end of Sunday (I know, Arduino Day is a one-day event, but this makes sure the sale lasts all Arduino Day in every time zone). You can find all of the sale items on our Arduino Day 2015 sale page.
Get FREE copies of Circuit Cellar magazine’s March issue and Elektor magazine’s March/April issue with your order, while supplies last. To get your free issues, enter the coupon codes CIRCUIT0315 and ELEKTOR0315 into your shopping cart.
