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,...

This powerful motor controller makes closed-loop speed or position (but not both!) control of a brushed DC motor easy, with quick configuration over USB using our free software. It supports five control interfaces: USB, TTL serial, I²C,...

This M2.5 hex nut is made from steel, is zinc-plated, and comes in packs of 25. General Specification Thread type:M2.5

This M2.5, pan-head screw is 6 mm long. It is made from steel, is zinc-plated, and comes in packs of 25. Dimension Length:6 mm General Specification Thread type:M2.5

Build your very own programmable balancing robot with the Balboa 32U4 robot kit! The Balboa control board features an Arduino-compatible ATmega32U4 MCU, motor drivers, quadrature encoders, and a full IMU. This board also has the ability...

90×10mm wheel with tire removed. Description These wheels are designed to press-fit securely onto the 3mm D output shafts on many of our gearmotors, including our micro metal gearmotors and our plastic gearmotors with 3mm D-shafts. They...

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...

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

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 S7V7F5 switching step-up/step-down regulator efficiently produces 5 V from input voltages between 2.7 V and 11.8 V. Its ability to convert both higher and lower input voltages makes it useful for applications where the power supply...

The D24V22Fx family of step-down voltage regulators generates lower output voltages from input voltages as high as 36 V. They are synchronous switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters)...
