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)...

This force-sensing resistor (FSR) from Interlink Electronics is a passive component that exhibits a decrease in resistance when there is an increase in the force applied to the 0.2″-diameter (0.5 cm) active area, allowing you to create a...

The Power HD 1235MG servo is all about torque. This 1/4-scale servo can deliver an incredible 560 oz-in of torque at 7.4 V or 490 oz-in at 6 V, and it features an all-metal gear train, digital control electronics, and two ball bearings...

These universal aluminum mounting hubs allow you to mount custom wheels and mechanisms to 5 mm diameter motor shafts. The set includes two hubs, two #4-40 set screws for securing the hubs to motor shafts, and one 0.05″ Allen wrench for...

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...

Add quadrature encoders to your 20D mm metal gearmotors (extended back shaft version required) with this kit that uses a magnetic disc and Hall effect sensors to provide 20 counts per revolution of the motor shaft. The sensors operate...

The A-Star 32U4 Prime SV is a programmable board based on Atmel’s ATmega32U4 microcontroller and arranged in the common Arduino form factor. The A-Star Prime offers many additional features and improvements over competing products,...

This tiny, button-type, vibrating motor shakes with a vibration amplitude of 0.75g and draws approximately 60 mA when 3 V is applied to its leads. The shaftless design keeps this motor small: 10 mm in diameter and 2.0 mm in height....

This gearmotor consists of a high-power, 6 V brushed DC motor combined with a 20.4:1 metal spur gearbox, and it has an integrated 48 CPR quadrature encoder on the motor shaft, which provides 979.62 counts per revolution of the gearbox’s...

This expansion plate for the Rover 5 tracked chassis is made of 1/8" (3mm) acrylic. The numerous 3 mm wide slots give you the flexibility to mount components in a variety of orientations almost anywhere on the plate. This 1/8" acrylic...
