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…

Micro metal gearmotors now available with long-life carbon brushes

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: Breakout Board for microSD Card with 3.3V Regulator and Level Shifters

New product: Breakout Board for microSD Card with 3.3V Regulator and Level Shifters

In September of last year, we started carrying our Breakout Board for microSD Card, which was the first board that I ever designed and routed here at Pololu. It is a simple breakout board that gives direct access to each contact available on a microSD card socket. However, since microSD cards operate at 3.3 V, it can be tricky interfacing them with a 5 V system. To address this, we made a new version with an integrated 3.3 V regulator and level shifters. Even with the extra components (and mounting holes, which the mechanical engineers at here Pololu are always pushing for), the board is still compact, measuring only 0.94″ × 0.9″, and it breaks out all of the contacts from a microSD card socket necessary to interface with the card through its SPI bus mode interface to a single 1×9 row of 0.1″-spaced pins. This allows easy use with breadboards, perfboards, or 0.1″ connectors.

You might recognize the circuit from our A-Star 32U4 Prime controllers, which use essentially the same level shifters to interface a microSD card with an Arduino-compatible ATmeg32U4 microcontroller running at 5 V.

For more information about this breakout board, see its product page.

New high-current stepper driver carrier with SPI: AMIS-30543

New high-current stepper driver carrier with SPI: AMIS-30543

This new board is a Pololu carrier for ON Semiconductor’s AMIS-30543 Micro-Stepping Motor Driver, which is a high-performance stepper motor driver with advanced features not found on our other stepper motor driver carriers.

AMIS-30543 stepper motor driver carrier, bottom view with dimensions.

The Pololu AMIS-30543 Stepper Motor Driver Carrier breaks out all of the important pins of the driver onto breadboard-compatible 0.1"-spaced pins, with optional terminal blocks for the power and motor connections and mounting holes for a more robust setup. Our board supplies reverse protection and all the necessary circuit components for interfacing to a microcontroller.

The AMIS-30543 is rated up to 30 V and 3 A, but (as with other stepper drivers) the current rating is a theoretical maximum assuming excellent cooling. Using our board at room temperature without a heatsink, the chip can practically supply about 1.8 A per coil, more than any of our other stepper motor driver carriers.

The SPI interface of the AMIS-30543 provides many exciting features: it lets you configure microstepping (down to 1/128-step), set the current limit, select voltage slopes, change direction, disable the outputs or put the driver to sleep, monitor the micro-step position and errors, and more. Please note, however, that you cannot step the motor over SPI.

Many of our customers have asked for software current limit control, since it allows better power management. For example, consider that stepper motors counter-intuitively use their maximum current when stopped, even if there is no holding torque required. This wastes a lot of power and generates undesirable heat in the drivers and motors. In a typical application like a 3D printer, where you don’t need much holding torque, you would want to reduce the current limit to a low value during pauses. You might use a higher limit (above the continuous limit) when accelerating and an intermediate value for constant-speed motion. The SPI current limit control on the AMIS-30543 lets you do all of this in your code.

Another advanced feature is the SLA (speed and load angle) output that indicates the level of the back-EMF voltage of the motor. This is an analog signal that can be used for stall detection or closed-loop control of the torque and speed:

AMIS-30543 stepper motor driver SLA output (green) and motor output (blue).

It is easy to get started using our Arduino library on GitHub, which provides basic functions for configuring and operating the driver as well as access to many of the advanced features. Please visit the product page for a detailed description, wiring diagrams, the AMIS-30543 datasheet, and more.

New 0.1″ male header strips

New 0.1″ male header strips

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

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.
