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...

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...

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...

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 5 V. The board measures only 0.7″ × 0.8″, but it allows a typical continuous output current of up to 5 A ....

These hexagonal male-female aluminum standoffs are intended specifically for use with the Raspberry Pi. They keep parts spaced 18.6 mm apart, which is just the right height for mounting expansion boards with extra-tall female headers,...
