Micro metal gearmotors now available with long-life carbon brushes

Posted by Ben on 12 June 2015
Tags: new products

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:

New product: 0.1″ low-profile male LCD header

New 0.1″ male header strips

Tags: new products

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 also now have right angle male header strips available in 2 rows or 3 rows:

0.100" (2.54 mm) Breakaway Male Header: 2×40-Pin, Right Angle.

0.100" (2.54 mm) Breakaway Male Header: 3×40-Pin, Right Angle.

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.

New products: 40×7 mm wheels

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).

Like the rest of the Pololu wheels, the 40×7 mm wheels press-fit onto the 3mm D shafts on many of our motors, including the micro metal gearmotors and mini plastic gearmotors.

New product: Sharp GP2Y0A60SZLF Analog Distance Sensor

Posted by Ben on 9 April 2015
Tags: new products

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.

Looking for Wixel feedback

Posted by Ben on 3 April 2015


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.
