New product: shorter 12 mm hex wheel adapter for 6mm shafts

We now have a shorter (20 mm) 12 mm Hex Wheel Adapter for 6 mm Shaft as an alternative to our original 35 mm extended version. These adapters work well with our 37D mm metal gearmotors, allowing you to use them with many common hobby RC wheels.

12mm Hex Wheel Adapter for 6mm Shaft connecting a Wild Thumper Wheel to a 37D mm Metal Gearmotor.

New motor driver carriers for the BD65496MUV and MAX14870

We have two exciting new DC motor driver carriers to introduce, one for ROHM’s BD65496MUV and one for Maxim’s MAX14870:

BD65496MUV Single Brushed DC Motor Driver Carrier, labeled top view.
MAX14870 Single Brushed DC Motor Driver Carrier, labeled top view.

These drivers each offer wide operating voltage ranges, with the BD65496MUV operating from as low as 2 V up to 16 V and the MAX14870 operating from 4.5 V all the way up to 36 V. They can each supply over an amp to a single, bidirectional brushed DC motor. These are the highest-performing integrated motor drivers we know of short of substantially larger units such as the MC33926 and VNH5019.

New products: Hakko tools

Most electronics projects (and many Pololu products) require soldering. That’s why we’re excited to offer a soldering station and other accessories that we can wholeheartedly recommend! We are now carrying Hakko soldering and desoldering tools and Hakko hand tools (cutters and pliers). We use Hakko tools in our own manufacturing, and we believe they offer a great mix of reliability, performance, and price. Continued…

New distributors in South America

Continuing with our belated new distributor introductions, we are happy to welcome these six new Pololu distributors in South America:

Baú da Eletrônica is a new Pololu distributor in São Paulo, Brazil. Check out their Pololu category for the 3pi Robot, Zumo, and more.


BUILDBOT, also in São Paulo, is now carrying the 3pi and Zumo as well as a variety of Pololu sensors, relay modules, and mechanical parts.


FILIPEFLOP is yet another new distributor in Brazil (bringing the total to eight), located in the city of Florianópolis. Make sure to check out their blog, which is full of useful-looking tutorials.


IMPORTRONIC, a robotics and electronics store in Quito, Ecuador, now features a Pololu category with a selection of our popular motors and servos.


Paruro.pe, in Lima, Peru, carries a large selection of electronics parts. Search for Pololu on their site to find our 3pi and Zumo, Arduino and Raspberry motor drivers, the Arduino-compatible A-Star Mini, and more.


Eneka is a new distributor with an interesting history. The store was founded by four brothers as a radio assembler/installer in Paris, France, and moved to Montevideo, Uruguay, in 1936 due to the deteriorating situation in Europe. Since then, they have become a distributor of electronics equipment and components, and they recently started adding robotics to their product line. Our first distributor in Uruguay, Eneka carries a number of Pololu parts including voltage regulators, sensors, motors, and wheels.

Robot contest in Mexico to be held at 14th National Congress of Mechatronics

Robot contest in Mexico to be held at 14th National Congress of Mechatronics

A contact at Mexican distributor Cosas de Ingeniería wrote to let us know about a contest he is helping organize in Juriquilla, Querétaro, Mexico. The Mexican Mechatronics Asociation (Asociación Mexicana de Mecatronica A.C.) will be hosting the 14th National Congress of Mechatronics (14º Congreso Nacional de Mecatrónica) 2nd Robotics Competition on October 15th through 17th this year. The three-day event will host several robotic competitions:

  • Autonomous Vehicle Competition (based on the Sparkfun Autonomous Vehicle Competition)
  • Insect Robot Race (insectoid robots try to be the first to travel 2 m over obstacles and uneven surfaces)
  • Mini-Sumo Competition (autonomous robots, similar to the one pictured above and our Zumo robots, fight to stay in a designated area)
  • Line Following Competition (autonomous robots follow a line-marked course as quickly as they can)

To keep up with the latest news about this competition, see the RoboticaAMM Facebook page, which also has dozens of pictures from the last competition.

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:

Bohlebots at the German Open in Robocup Soccer 1v1

In March, I wrote a blog post about the Bohlebots robotics team winning the West German Robocup Soccer 1v1. Since then, the Bohlebots team has gone on to win first and third in the German Open Robocup Soccer 1v1 with their two robotics teams.

Amanda's line following robot: Newbie

Amanda's line following robot: Newbie

Many of the engineers and robot enthusiasts here at Pololu competed in the LVBots 2015 line following competition. (For house rules and details about how the competition was judged, see the LVBots line following rules page.) Unlike most of my peers this was my first competition at LVBots, so I thought it was fitting to name my robot “Newbie”. Newbie uses a servo to steer the front wheels, creating fluid movements in and out of turns. At least that was the plan; unfortunately, Newbie had complications. Continued…

Continuing to catch up on our new distributor introductions, we are excited to welcome these new European distributors:

Transfer Multisort Electronik (TME) is an electronics distributor based in Łódź, Poland, with local offices in six countries around Europe and a catalog of 145,000 products. Their robotics category is now full of Pololu products. Scroll down to the end of this post for a video of their warehouse, including an impressive 23-meter-high automated storage rack.


GoTronic runs an online store with a physical storefront in Blagny, France, near the Belgian border. They have been in business since 1990 and sell all kinds of robotics parts and kits and electronics components. Search for “Pololu” to find wheels, motors, the Zumo Robot Kit for Arduino, Maestros, motor drivers, and more.


OM ELECTRONIQUE is an electronics shop and online store located in Grenoble, France, selling all kinds of electronics items from audio/visual equipment to robotics parts. You can check out their two-page Pololu category.


MCHobby – Microcontroleur Hobby is an online electronics store operating out of Waterloo, Belgium. They have put a huge amount of effort into supporting customers in France and Belgium with detailed French-language documentation for the products they carry. For examples, check out their Zumo page or this DRV8825 carrier tutorial.


Flikto Elektronik distributes our products alongside items from places like Adafruit, Arduino, and Sparkfun. Located in Cologne, Germany, they offer same-day, low-cost shipping throughout Europe, including free shipping within Germany for orders over €50.


Floris.cc is a shop run by Pieter Floris in Breda, Netherlands, distributing all kinds of “electronic thingies”. They are carrying a variety of Pololu products including motors, motor drivers, Maestro servo controllers, and the zumo Robot for Arduino. I noticed that they also offer something I have not seen at other places: a €5.00 soldering service to help people without soldering experience.


SPACE d.o.o. is a hobby shop located on the grounds of the Belgrade Fair complex in Serbia, now carrying Pololu parts including the 3pi and Zumo Robot for Arduino.


MechaDroid is a new electronics and robotics shop in Cham, Switzerland, selling Pololu motors, motor drivers. and more.
