The RoboClaw 2x7A is an intelligent motor controller designed to control two brushed DC motors at 7.5 Amps continuous with up to 15 Amps peak per channel. It can be controlled from USB, RC radio, PWM, TTL serial, analog and...

These step-up/step-down regulators take an input voltage from 3 V to 30 V and increase or decrease it as necessary to produce a fixed 5 V, 6 V, 9 V, or 12 V output, depending on the version. They are switching regulators (also called...

These universal mounting hubs are designed to work with most 4 mm diameter shafts, including round shafts, and “D” shafts. Each of the two included hubs has four mounting holes for #4-40 screws (not included), letting you mount custom...

Overview This ball caster kit includes a black ABS housing, a 1/2" diameter metal 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...

These small, two-pin, SPST momentary pushbuttons are intended for mounting to PCBs, but they can also be plugged into standard 0.1" breadboards as shown in the picture to the right. We use them as reset buttons and user pushbuttons in...

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 is a bulk-packaged version of our Black Edition A4988 Stepper Motor Driver Carrier that ships with 0.1″-pitch male header pins installed as shown in the main product picture, so no soldering is required to use it with an appropriate...

This 12 V light-duty (LD) linear actuator with a 5:1 gear reduction can lift loads up to 15 kgf [34 lbs or 150 N] and can withstand static loads up to 250 kgf [550 lbs or 2500 N]. It has a maximum speed of 43.9 mm/s [1.73″/s] at no load...

This 12 V light-duty (LD) linear actuator with a 20:1 gear reduction can lift loads up to 50 kgf [110 lbs or 500 N] and can withstand static loads up to 250 kgf [550 lbs or 2500 N]. It has a maximum speed of 14.6 mm/s [0.57″/s] at no...

These universal mounting hubs are designed to work with most 6 mm diameter shafts, including round shafts and “D” shafts. Each of the two included hubs has six mounting holes for #4-40 screws (not included), letting you mount custom...

The Pololu USB AVR Programmer v2 is a compact, low-cost in-system programmer (ISP) for Atmel’s AVR microcontrollers. The programmer provides an interface for transferring a compiled AVR program from your computer to the target AVR’s...

The D24V150Fx family of step-down voltage regulators are high-current synchronous switching regulators that generate lower output voltages from input voltages as high as 40 V. These types of regulators are also known as switched-mode...
