The Tic T249 USB Multi-Interface Stepper Motor Controller makes basic control of a stepper motor easy, with quick configuration over USB using our free software. The controller supports six control interfaces: USB, TTL serial, I²C,...

This powerful step-up/step-down regulator efficiently produces a fixed 24 V output from input voltages between 3 V and 30 V while allowing a typical output current of up to 2 A when the input voltage is close to the output voltage and...

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 50 V and efficiently reduces it to 5 V . The board measures only 0.7″ × 0.8″ yet delivers typical maximum continuous output currents between...

This small synchronous switching step-down (or buck) regulator takes an input voltage from 4.5 V to 50 V and efficiently reduces it to 3.3 V . The board measures only 0.7″ × 0.8″ yet delivers typical maximum continuous output currents...

The Pololu Pushbutton Power Switch is a compact, solid-state power switch that features built-in reverse-voltage protection and is controlled by a momentary pushbutton: one push turns on power and another push turns it off. This is a...

The RoboClaw 2x15A is an intelligent motor controller designed to control two brushed DC motors at 15 Amps continuous with up to 30 Amps peak per channel. It can be controlled from USB, RC radio, PWM, TTL serial, analog and...

Overview The Pololu Zumo chassis kit contains the components necessary to build a small, high-performance tracked robot platform that is compact enough to qualify for Mini Sumo competitions. Each side of the chassis has an idler sprocket...

The compact (0.5″ × 0.7″) D24V10F3 synchronous buck voltage regulator takes an input voltage of up to 36 V and efficiently reduces it to 3.3 V while allowing for a maximum output current of 1 A . This regulator offers typical...

This array of IR LED/phototransistor pairs is great for precisely identifying changes in reflectance (like line detection). It operates from 2.9 V to 5.5 V and offers dimmable brightness control independent of the supply voltage. In...

The Tamiya 70098 Universal Plate Set is a customizable chassis designed to be compatible with multiple Tamiya products. This set includes a plastic plate with an 11 x 31 grid of 3 mm holes spaced 5 mm apart, which provides space for many...

This #4-40, pan-head screw is 1/2" long. It is made from steel, is zinc-plated, and comes in packs of 25.

Description These 20 mm long aluminum adapters convert a 6 mm diameter shaft to a 12 mm hex shaft that is compatible with many common hobby RC wheels. The set includes two adapters, two M4 screws for securing wheels to the adapters, four...
