New product: 1.3" graphical OLED display

Posted by Kevin on 7 July 2021
Tags: new products

We’re now selling an OLED display module that you can use to add some fancy graphics to your project! This monochrome OLED screen measures 1.3 inches diagonally and uses a common SH1106 driver that can be controlled via SPI communication. (For more information, see its product page.)

Graphical OLED Display: 128×64, 1.3", White, SPI, controlled by an A-Star 328PB Micro running at 3.3V.

With a 128×64 grid of individually-controllable, high-contrast pixels, this OLED display can show a lot more information (and looks a lot cooler) than simple text-only LCD screens. We’re working on something that can take advantage of these enhanced graphical capabilities, so keep an eye out for updates!

New product: 5V Step-Up/Step-Down Voltage Regulator S13V30F5

Posted by Claire on 9 June 2021
Tags: new products

I started routing the PCB for the S13V30F5 5V step-up/step-down voltage regulator in January of 2020, and we were in the middle of testing the assembled prototypes when the pandemic shutdowns hit. Like lots of other things in 2020, the project got put on hold because appropriate testing requires a decent amount of equipment and is not the easiest thing to do remotely. That only makes it more exciting to announce that the S13V30F5, our most powerful step-up/step-down regulator, is now available! It operates from 2.8 V to 22 V and steps that voltage up or down as necessary to produce a fixed 5V output with typical efficiencies of 85% to 95%. As shown in the graph below, it can deliver around 3A continuously when the input is near 5V.

This new regulator measures just 0.9″ × 0.9″. That is almost half the size of our previously highest-power step-up/step-down units, the S18V20Fx family, which we have recently started rationing due to impacts from the global semiconductor shortages.

To help celebrate finally releasing the S13V30F5, we are offering an extra introductory special discount. The first hundred customers to use coupon code S13V30F5INTRO can get up to five units for just $9.95 each!

We are excited to announce the addition of new GF23-series high-speed linear actuators to our already extensive linear actuator selection. This brand new Glideforce series from Concentric International is specifically designed for high-speed, light-duty applications, offering almost twice the speed of our previously fastest options while still supporting almost the same dynamic loads. This video demonstrates the speeds of the four types of light-duty actuators we carry:


They are available in 2″, 4″, 6″, 8″, 10″, and 12″ lengths with or without a feedback potentiometer. The table below shows how these new units compare to our other light-duty options, which are slower but stronger:

New longer-range Pololu distance sensors

Posted by Kevin on 4 June 2021
Tags: new products

We released the first of our new Pololu distance sensors a few months ago, and now we’re releasing additional Pololu Digital Distance Sensors with longer ranges! These boards have the same form factor and pinout as both our old Sharp/Socle GP2Y0D8x carrier boards and the short-range Pololu distance sensors designed to replace those, but the new versions offer greatly increased detection and measurement ranges, opening up new possibilities in applications where longer-distance sensing capabilities are desired.

Comparison of a Pololu Carrier with Sharp GP2Y0D8x Digital Distance Sensor and two Pololu Digital Distance Sensors (irs16a and irs17a).

Like their shorter-range counterparts, these new Pololu distance sensors determine distance by using an integrated lidar module to measure the time of flight (ToF) of invisible, eye-safe infrared laser light. The new versions include four digital output versions, which simply indicate whether they detect an object within their respective range thresholds:

There are also two new versions with pulse width outputs, which encode a distance measurement in a pulsed signal:

(For more detail on how the different output types work, see the earlier announcement or the sensors’ product pages.)

This brings us up to ten different Pololu distance sensor options, as shown in these tables:

2 Objects closer than the minimum distance can still be detected, but the measured distance might be inaccurate. The minimum detection range is < 5 mm for irs16a boards and < 1 mm for irs17a boards.

We’ve also just published comprehensive information about all the possible jumper settings for these sensor boards on their respective product pages. By changing the jumper connections, you can make a sensor act like a different version or even select another configuration that isn’t available as a standard product. (And if you have a special volume requirement, we can manufacture a custom batch of sensors for you; please contact us for more information.)

Once again, we are offering an extra introductory special discount on these sensors, to help share in our celebration of releasing new products. The first hundred customers to use coupon code DISTSENSORS can get up to three units of each type (including the shorter-ranged versions released earlier) for just $9.95 each!

New Pololu distance sensors with digital and pulse width outputs

Posted by Kevin on 6 February 2021
Tags: new products

In many applications ranging from robotics to industrial automation, it is useful to quickly detect the presence of objects within a certain distance. Our carrier boards for the Sharp/Socle GP2Y0D8x digital distance sensors have been popular in this role, but those sensors are unfortunately no longer being produced and are becoming hard to find. So we are excited to announce the release of our next-generation lidar-based Pololu Digital Distance Sensors, which can replace the discontinued Sharp sensors and more!

Comparison of a Pololu Carrier with Sharp GP2Y0D8x Digital Distance Sensor and a Pololu Digital Distance Sensor (irs16a).

Comparison of a Pololu Carrier with Sharp GP2Y0D8x Digital Distance Sensor and a Pololu Digital Distance Sensor (irs16a).

These new sensors use an on-board rangefinder module to determine distance by measuring the time of flight (ToF) of invisible, eye-safe infrared laser light. They are available in three different digital output versions with the same range thresholds as the GP2Y0D8x series:

We also have one additional option for more advanced applications:

(More on that version below.)

A camera with no IR filter shows the infrared light emitted by a Pololu Digital Distance Sensor.

The Pololu Digital Distance Sensors work like the Sharp sensors: they operate with either a 3.3 V or 5 V supply and output a simple digital signal, which is low if an object is detected within the specified range, high otherwise. They have the same indicator LED, pinout, and form factor as our GP2Y0D8x carrier boards (but are much thinner than the Sharp sensors), allowing them to be drop-in replacements in most applications.

The pulse width output version looks almost identical to its digital output counterparts, but instead of simply indicating the presence or absence of an object, it outputs a pulsed signal (similar to a hobby servo control signal) that encodes the distance it is measuring in the length of each high pulse. By timing these pulses, you can get quantitative range readings for targets up to half a meter away (depending on reflectance and environmental conditions).

The four numbered surface-mount jumpers on these sensors’ printed circuit boards, near the mounting hole on the front side, determine the sensor’s operating mode. You can change the jumper connections yourself to customize its behavior and even effectively convert the sensor into a different version (more information on the jumper settings will be available soon). And since we assemble and program these boards here in our Las Vegas facility, we can produce a custom-configured batch of sensors for you. If you are interested in manufacturing customization, please contact us for more information.

We are back to offering an introductory special discount on new products, to help share in our celebration of releasing these Pololu distance sensors. The first hundred customers to use coupon code DISTSENSORS can get up to three units of each type for just $7.87 each!

New Products: CP2102N serial adapter and another USB Type-C breakout. Should we do more with USB-C?

Posted by Kevin on 24 December 2020
Tags: new products

Seven years ago, we released a CP2104 USB-to-Serial Adapter Carrier, our first product with a USB Micro-B connector (we had only used Mini-B up to that point). A few months later I wrote a blog post discussing our decision to switch connector types, and since then, we have exclusively used the Micro-B connector in all of our USB products.

Well, it’s now 2020 and we recently released a CP2102N USB-to-Serial Adapter Carrier to replace the CP2104 board, along with a breakout for a different type of USB connector: our USB 2.0 Type-C Connector Breakout Board (usb07b). These products do not seem to have much in common at first glance (other than both being related to USB), but I think they create a good opportunity to talk about USB connectors again.

First, a bit about these new boards:

The CP2102N is Silicon Labs’ replacement for several of their older USB-to-UART bridge ICs that are going out of production, including the CP2104. (It is not to be confused with the even older CP2102 without the “N”, featured on our first USB-to-serial adapter and also being phased out.) Compared to the CP2104, the CP2102N has similar functionality but includes a few small improvements, such as a higher maximum baud rate and a re-programmable configuration ROM. Our CP2102N carrier can be used as a drop-in replacement for our CP2104 board in most applications. For more information, see the product page for the CP2102N USB-to-Serial Adapter Carrier.

Our usb07b connector breakout board is very similar to the first Type-C breakout (usb07a) that we released last year. The two boards use different styles of connectors, and the newer one is priced a bit lower, but they both provide access to all of the USB-C connections required for USB 2.0 operation (power, USB 2.0 data, configuration, and sideband pins) and feature integrated CC pull-down resistors that make it easy to use the port as a power sink. For more information, see the product page for the USB 2.0 Type-C Connector Breakout Board (usb07b).

So now, the obvious question is: Why doesn’t this new serial adapter have a USB Type-C connector?

When we designed and released the CP2104 board in 2013, the USB Type-C connector did not even exist yet. (Its development was probably well under way, but the specification was not finalized until August 2014.) Since then, USB-C connectors have started appearing in all kinds of devices and are becoming increasingly widespread. They offer the promise of a single type of connector that can be used everywhere, supporting faster data transfer, higher power, and alternate modes. On top of all that, the connector is reversible, so you don’t have to worry about getting the orientation of the plug right.

With those advantages in mind, it’s reasonable to wonder why we haven’t started using the Type-C connector in more products. I touched on some of the challenges introduced by USB Type-C when I announced for our first USB-C breakout board, and that increased complexity accounts for part of the explanation here. A full-featured Type-C connector like the one on usb07a has 24 separate pins, way more than the five on a Micro-B connector, which means it’s significantly harder both to design a printed circuit board for it and to ensure good quality and yields when manufacturing that board (especially since half of the contacts on the usb07a connector are small, tightly-packed through-hole pins). Because it is more mechanically complex, the Type-C receptacle usually also costs quite a bit more than a Micro-B connector.

The connector on our new usb07b board improves the situation a bit. It does not expose the eight USB 3 SuperSpeed signals (which we did not make available on our usb07a breakout anyway), and some of the power and ground pins are paired up more conveniently. So this connector effectively has just 12 pins, and they are all surface-mount, which helps lessen some of the design and manufacturing challenges I mentioned. The connector’s simpler construction makes it slightly less expensive as well.

Bottom view comparison of the USB Type-C connectors used on our usb07a (left) and usb07b (right) breakout boards.

This means it’s now a little bit more practical for us to consider a Type-C connector for more applications. However, there is still some question of what is to be gained by switching to it. While the enhanced power delivery capabilities of USB 3 and Type-C might open up some interesting possibilities for new kinds of devices, it’s not clear that our existing products would benefit much from a change to USB-C, and there are some features like SuperSpeed communication that we are not likely to take advantage of anytime soon with the types of electronics we make.

So we want to ask you: what products, revised or new, would you like to see us make with USB Type-C? Would a device have to be uniquely enabled by Type-C in order to be compelling (maybe something like a USB bus-powered motor controller), or is just having a reversible connector alone worth it, and would you be willing to pay a couple extra dollars to get something with a Type-C connector instead of Micro-B? What else about USB-C appeals to you? Please let us know in the comments!

New Products: JST SH-Style cables and connectors for Micro Metal Gearmotor encoders

Posted by Emily on 9 December 2020
Tags: new products

We have expanded our selection of JST SH-style cables and connectors! These cables and connectors are ideal for use with our magnetic encoders for Micro Metal Gearmotors as seen in the photo on the right above.

In addition to the 6-pin single-ended female JST SH-style cables we’ve offered for a while, we now offer 6-pin female-female JST SH-style cables in five different lengths. Here’s the full list of currently available options:

To go along with the new female-female cables, we also have breakout boards available for both the side-entry and top-entry versions of the JST SH-style connector. When used with our encoders and JST cables, these breakout boards offer a convenient way to access the encoder signal and power pins through a breadboard, and the pins are labeled on the board’s bottom silkscreen with this application in mind. Alternatively, these boards can serve as general-purpose breakouts for other applications that do not involve encoders. For example, a pair of connector breakouts with a female-female cable could be used as a removable general-purpose interconnect between different parts of a modular system.

We are trying something new with how we package and sell these connector boards. At Pololu, all our electronics undergo functional testing, where each product is placed on a custom testing apparatus and checked for functionality. This is a labor intensive step in our production process, and for a product as simple as these connector boards, testing and packaging represent a significant amount of the cost to produce it. As such, we are offering two options for purchasing these connector boards: either fully tested and individually packaged, or an untested pack of three.

Even though we do not functionally test the discounted 3-packs, each one undergoes automated optical inspection (AOI) to visually check the placement of the connector and the quality of the solder joints. Additionally, each printed circuit board (PCB) is electrically tested by our PCB manufacturer, so we know the PCB itself is free from electrical defects. This makes it very unlikely for any of the breakout boards to be bad.

The additional functional testing we perform on the fully tested units just confirms the solder connections between the connector and the board. If you purchase the untested units but would still like this additional confirmation, you can easily check it yourself with a multimeter. (Just use it to check for continuity between corresponding pins on the actual JST connector and through-holes on the board, and verify that there is no continuity between adjacent pins.) In the unlikely event you receive a unit with a poor or shorted connection, you should be able to touch it up yourself with a soldering iron. So for common applications that require two boards, such as use with a pair of encoders, you have the option of two individually packaged units we have confirmed functional or, for the same price, three units that have passed visual inspection and are very likely to leave you with two functional units plus a spare.

All units automatically optically inspected.

Here are all of our 6-pin JST SH-style connector options:

All of these cables and connectors and the encoders they are compatible with can be found here. And you can get 15% off the encoders and cables using coupons from our Christmas Sale going on now!

What do you think about this kind of approach where we test something less thoroughly in order to offer it at a lower price? Would you prefer it over the fully tested option? Do you think one option will be more popular than the other? We’d love to hear your thoughts!

Our newest robot, 3pi+, is here—Arduino-compatible, USB, encoders, full IMU and more!

Posted by Jan on 23 November 2020

I am thrilled to announce the release of our newest robot, the 3pi+! This new platform is a major upgrade from the original 3pi robot we introduced twelve years ago. At 97 mm, the diameter is just 1mm larger than the original, and the general concept of a tiny, fast robot powered by four AAA batteries and two micro metal gearmotors remains the same. However, just about everything has been redesigned from the ground up to add the extra features everyone has been asking for.

First off, the 3pi+ is now a platform that encompasses a range of products, not just one particular robot. This is enabled primarily by the chassis now being an independent structure rather than being a specific circuit board with motors strapped on:

3pi+ Chassis Kit (No Motors or Electronics).

The chassis incorporates the battery holders, motor mounts, and ball caster. An outer bumper skirt is removable and the motors can instead be held in by separate clips (also included in the kit). The left-most picture shows the chassis with motors installed but without the bumper skirt or motor clips, and the next two pictures show the motor clips installed:

Making the chassis separate from any electronics means that you can use it with your own electronics and that we can make various versions with different capabilities and microcontrollers.

3pi+ 32U4

The first full 3pi+ robot we are launching is the 3pi+ 32U4, which is based on an Arduino-compatible ATmega32U4 microcontroller from Microchip (formerly from Atmel). Like the original 3pi, the 3pi+ 32U4 has five integrated downward-looking reflectance sensors, making the robot a great starting point for line following and line-maze events.

The 3pi+ 32U4 offers many major improvements over the original 3pi, including:

  • ATmega32U4 microcontroller with Arduino-compatible bootloader can be programmed directly through a USB connection
  • Quadrature encoders on both motors for closed-loop position and speed control
  • Full 9-axis IMU (three-axis gyro, accelerometer, and compass)
  • Bottom-loading battery holders keep batteries accessible even if additional levels are added
  • Full wrap-around bumper to protect electronics from collisions
  • Two bump sensors on the front

3pi+ 32U4 Robot features, top view.

3pi+ 32U4 Robot features, bottom view.

The 3pi+ 32U4 is also available with three motor options for different usage scenarios:

3pi+ 32U4 Version Products Micro Metal Gearmotor Top Speed Comments
Standard Edition assembled or kit 30:1 MP 6V 1.5 m/s great all-around balance between controllability and speed, with top theoretical speed above that of the original 3pi
Turtle Edition assembled or kit 75:1 LP 6V 0.4 m/s longest battery life, easiest to control, appropriate for swarm robot projects or classrooms where you might not want robots flying around the floor (or desktop) too quickly
Hyper Edition assembled or kit 15:1 HPCB 6V ~4 m/s ridiculous speed, which can definitely be fun. But, controlling that speed can be difficult, which can make the robot more prone to self-destruction (or at least self-inflicted damage), so we recommend this only for advanced users

These three 3pi+ 32U4 motor options are available in assembled or kit form, and for those who want to do your own thing, the parts are available separately so that you can pick some other motor or gear ratio.

Normally we would have an introductory special for this big of a new product release, but since we are about to launch our annual Black Friday and Cyber Monday sale, you can get a great discount on the new 3pi+ there!

New product: VL53L3CX Time-of-Flight Multi-Target Distance Sensor Carrier

Posted by Kevin on 2 October 2020
Tags: new products

December 2020 update: ST originally specified a 3 m (10 ft) maximum range for the VL53L3CX, and we initially released this product with the name “VL53L3CX Time-of-Flight Multi-Target Distance Sensor Carrier with Voltage Regulator, 300cm Max”. However, they have since released an updated API with software improvements that increase the maximum range to 5 m (16 ft), so we have updated the name of this product accordingly. The latest version of the API should enable this increased range on existing boards as well as new ones; the hardware has not changed.

Please note that the rest of this post has not been updated to reflect the increased 5 m range (which now exceeds the VL53L1X’s 4 m range).

We are now offering a VL53L3CX Time-of-Flight Multi-Target Distance Sensor Carrier. The VL53L3CX is one of ST’s latest ranging sensors featuring their FlightSense technology, which determines distance by measuring how long it takes for emitted light to be reflected from a target and arrive back at the sensor. It can work at distances of up to 3 m, putting the VL53L3CX’s effective range in between those of ST’s older VL53L1X and VL53L0X integrated lidar modules.

Beyond just being an intermediate option, the VL53L3CX is interesting because it has the ability to detect multiple targets within its field of view. This is possible because instead of picking out a single distance based on the reflections received by the sensor, the VL53L3CX outputs histogram data representing how much reflected light it is receiving within different time intervals. The host processor can then read this data through a digital I²C interface and analyze it using special algorithms that ST provides as part of their VL53L3CX API.

This enhanced capability does come at a cost: the added complexity of the histogram processing means that the host requires much more RAM and program memory, making the VL53L3CX difficult to use with small microcontrollers. In our testing, we were unable to fit the VL53L3CX API on a typical 8-bit Arduino, and we are not providing an Arduino library to support the VL53L3CX; therefore, we recommend sticking with the VL53L1X or VL53L0X for applications with similar constraints. However, if you have more resources available on something like a 32-bit processor, the VL53L3CX’s multi-target detection might give you valuable information beyond what you could determine from a distance reading alone.

For more information about the VL53L3CX carrier, see its product page. The first 100 customers can use VL53L3CXINTRO to get up to 7 units for just $7.77 each!

First new products under emergency operations - new servo wheels!

Posted by Jan on 7 May 2020

We are into May, and after almost 8 weeks of shutdowns and emergency operations, most of the world’s attention seems to be moving toward reopening and how to return to some semblance of normal, or at least longer-term sustainable operations. With no particular medical solution even on the horizon, it’s clear that we have a long way to go, and a city like Las Vegas is going to be hurt especially hard and for a long time by changes people will adopt until they are comfortable flying for fun again. Pololu has managed to hold up much better than I initially feared during the first week of mandated shutdowns, and I am especially grateful to all of our customers and staff members who have worked hard to get us this far.

It is with this backdrop of gratitude for making it this far while realizing we still have a long way to go that I am especially excited to announce our first new products released since the pandemic hit!

In all, we have eight new wheels for micro and standard sized servos. These are red and white versions of the four sizes we released in black back in January. Since we are operating with a minimum staff on site, we don’t have many actual pictures of the new wheels in action, so I will use the pictures with older black wheels for the rest of the post.

Black Pololu Wheels for Standard and Micro Servos – 90, 70, 60, and 40 mm diameters.

We have small, 40 mm and 60 mm sizes that are compatible with micro servo splines with 20 teeth and a 4.8 mm diameter and can be used with the following continuous rotation servos that we carry:

We have larger 70 mm and 90 mm sizes that are compatible with standard servo splines with 25 teeth and a 5.8 mm diameter and can be used with the following continuous rotation servos we carry:

If you plan on using the wheels with a servo not listed above, be sure to check your servo’s specifications for compatibility as servo splines are not standardized.

I was never especially fond of continuous-rotation servos, but there’s no denying that they’re often a quick and relatively simple way to get something moving, both from the electronics side (since the motor controller is built into the servo) and the software side. I am a fan of building your own unique robots, so I am happy we now have a range of size and color choices to give you more problem-solving options and variety in your robots.

Like many of our plastic products, these wheels were designed by us in Las Vegas and then injection molded in China. Since we already had the design and molds finished before we released the black versions, these new products are not the most new from a design perspective. We made the black ones first, and red and white were supposed to follow shortly after the Chinese New Year holiday. As we all got reminded, things don’t always go according to plan. And now, what should have been a minor new product has additional sentimental meaning as our first new product since the coronavirus upended our lives and a symbol of our determination to carry on.

We had been announcing new products along with introductory discounts for the last few years, and I wavered for a bit about doing extra discounts for these wheels. Shipping costs have gone up dramatically, and we’re trying to raise whatever money we can, so extra discounts are not the first thing I felt like doing. But the whole point is that we do want to celebrate at least a little! So, hooray for the continuation of the new product discount tradition:

The first hundred customers to use coupon code SERVOWHEELS can get 22% off up to 3 pairs of each size! And, if you are one of the lucky ones not especially financially hurt by the pandemic and are interested in these wheels, please consider getting them without the coupon or even donating to help Pololu keep operating. We have set up item 2400 for donating in $1 increments.

Thank you to all of you who have donated to us or otherwise supported us over the past two months. Stay safe and healthy, everybody!
