The compact (0.5″ × 0.7″) D24V10F9 synchronous buck voltage regulator takes an input voltage of up to 36 V and efficiently reduces it to 9 V while allowing for a maximum output current of 1 A. This regulator offers typical efficiencies between 85% and 93% and has a very l...

SKU: PL-799

Overview The Pololu adjustable boost regulator is a very flexible switching regulator (also called a switched-mode power supply, SMPS, or DC-to-DC converter) that can generate voltages higher than its input voltage. We offer two adjustable ranges: approximately 2.5 V to 9.5 V and ...

SKU: PL-2675

This two-part aluminum assembly mounts directly to 1/4 inch diameter motor output shafts like those on our NEMA 23 stepper motors and allows you to drive most scooter, skateboard, inline skate, and other common wheels that are compatible with popular 608 ball bearings. Two M4 set screws are...

SKU: PL-2692

This ball caster is an improved version of our original Pololu Ball Caster with 1″ Plastic Ball; we recommend this new version over the older version for all applications that are not somehow specifically tied to the previous design.This ball caster kit includes a two-part black ABS housing, a 1″...

SKU: PL-954

This light ball caster uses a 3/4″ diameter plastic ball. The height of the assembled kit ranges from 0.9″ to 1.2″, depending on the combination of included spacers used. Included dowel pins can be used to reduce the friction between the ball and the ABS housing, but they are not necessary for o...
