This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 3.3 V . The board measures only 0.7″ × 0.7″, but it allows a typical continuous output current of up to 2.5...

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″ × 0.7″, but it allows a typical continuous output current of up to 2.5 A...

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 ....

This rugged, 4-wheel-drive chassis from Dagu Electronics is a smaller version of the Wild Thumper 6WD chassis. It is designed to excel at traversing rough terrain, making it a great platform for any robot that needs to perform tasks in a...

This module is a compact breakout board for ST’s high-power VNH2SP30 orVNH3SP30 motor driver IC, each of which is a fully integrated H-bridge that can be used for bidirectional speed control of a single brushed DC motor. The basic...

Overview DRV8838 Single Brushed DC Motor Driver Carrier, bottom view with dimensions. TI SN754410 (16-pin DIP) next to the #2135 DRV8835 carrier (14-pin DIP) and #2990 DRV8838 carrier (10-pin DIP) for size reference. Texas Instruments’...

DRV8833 dual motor driver carrier, bottom view with dimensions. Texas Instruments’ DRV8833 is a dual H-bridge motor driver IC that can be used for bidirectional control of two brushed DC motors at 2.7 V to 10.8 V. It can supply up to...

Overview This ball caster kit includes a black ABS housing, a 1/2" diameter metal ball, two spacers (1/16" and 1/8" thick), and two #2 screw sets. The total height of the ball caster, 0.53", can be increased to about 0.7" using the...

These tiny brushed DC gearmotors are intended for use at 6 V, though in general, these kinds of motors can run at voltages above and below this nominal voltage, so they should comfortably operate in the 3 – 9 V range (rotation can start...
