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

via Pololu Blog

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!

New high-speed linear actuators

via Pololu Blog

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

via Pololu Blog

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:

1 Effective range depends on object reflectivity and ambient lighting conditions.
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!
