Winner of the Dr. Toy 100 Best Children’s Products award, the Snap Circuits educational kits by Elenco are a great way to learn about electronic circuits. Each Snap Circuits kit comes with full-color manuals and color-coded,...

If you’ve never soldered before but want to explore the world of robotics and electronics, this kit is for you! A soldering iron, solder, and diagonal cutters are included in this very complete kit. The flashing LEDs and a siren will let...

The Wixel shield seamlessly enables a wireless link (with a typical range of ~50 feet) to duplicate the functionality of your Arduino’s USB interface, which means you can use the standard Arduino computer software to: wirelessly program...

This ball caster kit includes a black ABS housing, a 1/2" diameter plastic ball, two spacers (1/16" and 1/8" thick), and two #2 screw sets. The total height of the ball caster, 0.53", can be increased to about 0.7" using the included...

This ball caster can be used as a replacement 3pi robot part or as a general-purpose ball caster. When mounted through a hole in a chassis that uses our micro metal gearmotors and our 32×7mm wheels , as on the 3pi, this ball caster is...

These plastic mounting brackets allow you to easily and securely mount the ubiquitous 10 mm x 12 mm x 26 mm metal gearhead motors first popularized by Sanyo’s 12GN series (e.g. NA1S…NA3S), such as ourmicro metal gearmotors and the...

This brushed DC gearmotor is very compact and weighs only 0.7 ounces (19.5 grams) — perfect for building a quick, miniature robot. The recommended operating voltage range for this motor is 3 to 6 V, though the gearmotor can start...

This #2-56, pan-head screw is 1" long. It is made from steel, is zinc-plated, and comes in packs of 25. Dimensions · Length: 1.00 in General Specifications · Threaded type: 2-56

DRV8824/DRV8825 stepper motor driver carrier with dimensions Overview This product is a carrier board or breakout board for TI’s DRV8825 stepper motor driver; we therefore recommend careful reading of the DRV8825 datasheet (1MB pdf)...

Zumo reflectance sensor array with labeled sensors and dimensions. The Zumo reflectance sensor array provides an easy way to add line sensing or edge detection to a Zumo robot . It features six separate reflectance sensors, each...

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...

Overview This 5 V boost (step-up) voltage regulator generates higher output voltages from input voltages as low as 0.5 V, and it also automatically switches to a linear down-regulation mode when the input voltage exceeds the output. This...
