This post is a few weeks late, but I am following up on my original D24V22F12 12V regulator introduction to let you know that we now have 3.3 V, 5 V, 6 V, 7.5 V, 9 V, and 12 V versions of our new D24V22Fx family of step-down voltage regulators. These regulators all have typical efficiencies of 85% to 95% and can deliver continuous currents over 2 A in typical applications.
The new D24V22Fx regulators are priced lower than the older D24V25Fx family that they will be replacing. The two designs have the same size and similar current capabilities and input voltage ranges, but they do not have the same pinout and are based on different internal circuits, so there are fundamental differences in operation. In particular, these newer D24V22Fx regulators have much lower dropout voltages and provide a “power good” signal, and the newer design allows for higher output voltages (e.g. 12 V).
All of the sale details are now listed on our Black Friday/Cyber Monday sale page. Check them out and get your carts ready because the sale starts in less than six hours! Here are just some of the deals:
Our biggest sale of the year is less than two days away! As in previous years, we are offering huge discounts on hundreds of products, but we’re also introducing a new feature this time around: upgrades to the next best price break on the rest of the products we carry. You will also be able to select free bonus items with orders over $100. We have put up some of the special offers on the Black Friday/Cyber Monday sale page; stay tuned for more details, including the full list of discounted products and coupon codes.
Our 37D mm metal gearmotors now have fitted plastic end caps over their encoders that neatly protect the assembly and keep stray objects clear of the magnetic disc. The pictures below show the previous version (without end cap) next to one of the new ones:
The end cap is easily removable if you need to access the encoder or want a few more millimeters of clearance for your gearmotor, but there is a little bit of base plastic that will remain (as shown in the picture below), so removing the end cap does not quite make these new ones identical to the previous versions.

These gearmotors are available in six different gear ratios and with or without encoders, and we also carry the motor and encoder assembly by itself with no gearbox. The following table shows all of our 37D mm metal gearmotor options:

It has been a few months since we introduced our new high-power micro metal gearmotors with longer life carbon brushes. We now have them available with dual shafts, and we have made a corresponding update to our magnetic encoders to let them work with the larger terminals of the HPCB motors.
You might see similar-looking motors elsewhere, but no one comes close to our offering, from the quality of the gears to the variety of winding options to the selection of gear ratios, all in stock for shipment the day you order. By bringing together Pololu’s exclusive features of high-power windings, long-life carbon brushes, and encoders for closed-loop feedback control into a single package, these latest motors and encoders really demonstrate our continual investment in this popular form factor. With ten gear ratios available, from 10:1 through 1000:1, our total selection of micro metal gearmotors has grown to nearly 70 options:

You can see all ten of the new versions below, and if there are any versions we do not yet have that you would like to see us carry, let us know in the comments!
Halloween is just around the corner, but there is still time for you makers out there to build terrifying interactive props and amazing costumes, and we want to help. From now through October 21, we are having a sale on servos and servo controllers, proximity sensors, programmable microcontroller boards, power supplies, and more – all the products you might want to bring your creepy creations to life. See the sale page for more details and the full list of products.
If you need some inspiration, check out our sample Halloween projects, and as always, we would love to hear about anything cool you make with our products; we might feature it on the blog!
We are pleased to introduce our new 12 V, 2.2 A switching regulator, the inaugural member of the D24V22Fx family of step down voltage regulators. We expect to release other voltage versions next month, but we wanted to get a 12 V version out right away since we did not offer a 12 V buck regulator that could do more than 1 A. The compact regulator works with input voltages up to 36 V and can typically deliver up to a continuous 2.2 A. It offers integrated reverse voltage protection along with over-current and over-temperature shutoff, and a power-good output can be used to determine when the regulator cannot maintain its output voltage.
Unlike linear regulators which waste a lot of power and generate a lot of heat in the process, this new regulator is very efficient, which means you can get the most out of your battery life:
Until we release other voltage versions of the D24V22Fx, the closest substitutes are the similar D24V25Fx family of step-down voltage regulators:
These regulators are the same size as the D24V22F12 and they have similar current capabilities and input voltage ranges, but they do not have the same pinout and they are based on a different internal design, so there are fundamental differences in operation.
Continuous rotation servos like FEETECH’s FS90R are popular actuators for beginner robots because of their low cost and ease of use—since the motor controller is built right into the actuator, it can be controlled directly from a microcontroller or RC receiver. However, to complete the drive system, you need wheels, and that is something that we have not been able to offer for the FS90R until today. I am excited to introduce the new 60×8mm wheels for FS90R micro servos, which should make it much easier to get your FS90R-based miniature robot rolling.
All that said, we still generally recommend creating custom drive systems out of individual motor drivers, DC motors, and wheels over continuous rotations servos, since that gives you much more control over performance. Continuous rotation servos are more appropriate for projects where cost and simplicity are more important than performance, and with these wheels and the FS90R, this approach is simpler and more affordable than ever.
