This item is a set of three plastic rollers, a 1″-diameter plastic ball, and a retaining clip that can be used on the front or back ball caster locations on the Romi chassis base plate. The ball is white, and all other parts are black ....

The versatile Romi chassis is a great starting point for your next mobile robot. This kit includes all the basic mechanical parts to get up and running, including two motors, two wheels, one ball caster, and battery contacts. The wheels...

These white plastic wheels press-fit onto the 3mm D shafts on many of our motors, including our micro metal gearmotors and our mini plastic gearmotors, to make a nice drive solution for small robots. The wheels have silicone tires and...

This version of our TB67S249FTG Stepper Motor Driver Compact Carrier ships with male header pins installed , so no soldering is required to use it with an appropriate 16-pin socket or solderless breadboard. The TB67S249FTG has a wide...

This breakout board makes it easy to use Toshiba’s TB67S249FTG microstepping bipolar stepper motor driver, which features adjustable current limiting and seven microstep resolutions (down to 1/32-step). In addition, it dynamically...

The S9V11x family of efficient switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) use a buck-boost topology to convert both higher and lower input voltages to a regulated output voltage. They...

These tiny brushed DC gearmotors are available in a wide range of gear ratios—from 5:1 up to 1000:1—and with five different motors: high-power 6 V and 12 V motors with long-life carbon brushes (HPCB), and high-power (HP), medium power...

These tiny brushed DC gearmotors are intended for use at 6 V, though in general, these kinds of motors can run at voltages above and below this nominal voltage, so they should comfortably operate in the 3 – 9 V range (rotation can start...

This gearmotor is a miniature high-power, 12 V brushed DC motor with long-life carbon brushes and a 51.45:1 metal gearbox. It has a cross section of 10 × 12 mm, and the D-shaped gearbox output shaft is 9 mm long and 3 mm in diameter. Key...
