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...

Overview The Pololu step-up/step-down voltage regulator S10V4F5 is a switching regulator (also called a switched-mode power supply (SMPS) or DC-to-DC converter) with a single-ended primary-inductor converter (SEPIC) topology. It takes an...

This compact bracket enables convenient mounting of popular, Sanyo-style micro metal gearmotors. The white plastic bracket encloses the otherwise exposed gears, and the mounting tabs capture the nuts for easy installation. The brackets...

This small ball caster uses a 3/8″ diameter metal ball. The height of the assembled kit ranges from 0.4″ to 0.6″. This ball caster kit includes a black ABS housing, a 3/8″ diameter metal ball, two spacers (1/16″ and 1/8″ thick), and two...

These boost (step-up) voltage regulators generate higher output voltages from input voltages as low as 2.9 V. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) and have a typical...

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 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...

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

This breadboard-compatible module is an alternative to bulky power switches. It uses a small integrated slide switch to control a high-side power MOSFET that can deliver continuous currents up to around 6 A at 2 V to 20 V . The board...

This product is a power switch implemented as a pair of P-channel MOSFETs configured as a high-side switch with reverse voltage protection and controlled by a micro slide switch. Because the main current does not go through the...

Overview This product is a carrier board or breakout board for TI’s DRV8834 low-voltage stepper motor driver; we therefore recommend careful reading of the DRV8834 datasheet (2MB pdf) before using this product. This stepper motor driver...

The VM-CLAP1 Hand Clap Sensor from Verbal Machines is a low-power, microprocessor-based audio sensor that can detect hand claps or finger snaps while ignoring background noises such as human speech or music. It operates from 2.5 V to 5.5...
