Overview This current sensor is a carrier board or breakout board for Allegro’s ACS709LLFTR-35BB-T Hall effect-based linear current sensor with overcurrent fault output; we therefore recommend careful reading of the ACS709 datasheet...

Overview This current sensor is a carrier board or breakout board for Allegro’s ACS715LLCTR-30A-T Hall effect-based linear current sensor; we therefore recommend careful reading of the ACS715 datasheet (593k pdf) before using this...

Overview This current sensor is a carrier board or breakout board for Allegro’s ACS711KLCTR-25AB-T Hall effect-based linear current sensor with overcurrent fault output; we therefore recommend careful reading of the ACS711 datasheet...

Overview The Pololu high-power motor driver is a discrete MOSFET H-bridge designed to drive large DC brushed motors. The H-bridge is made up of two N-channel MOSFET per leg, and most of the board’s performance is determined by these...

The Wixel shield seamlessly enables a wireless link (with a typical range of ~50 feet) to duplicate the functionality of your Arduino’s USB interface, which means you can use the standard Arduino computer software to: wirelessly program...

This brushed DC gearmotor is very compact and weighs only 0.7 ounces (19.5 grams) — perfect for building a quick, miniature robot. The recommended operating voltage range for this motor is 3 to 6 V, though the gearmotor can start...

Tamiya’s steel-ball caster is a good way to give a “third wheel” to a small robot powered by a differential drive. The kit comes with enough parts to make two casters, either 25 mm or 35 mm in height. The Tamiya 70144 ball caster from...

This gearmotor consists of a low-power, 6 V brushed DC motor combined with a 171.79:1 metal spur gearbox, and it has an integrated 48 CPR quadrature encoder on the motor shaft, which provides 8245.92 counts per revolution of the...

This 120:1 gearmotor (gearbox with brushed DC motor) is very compact and weighs only 0.7 ounces (20 grams) — perfect for building a quick, miniature robot. This gearmotor starts rotation at 0.58 V, drawing only 46.5 mA at 7 RPM. At 5 V,...

Overview The Tamiya 4-speed crank-axle gearbox has four possible gear ratios, including the highest gear ratio of Tamiya’s gearbox series, 5402:1, as well as 126:1, 441:1, and 1543:1. This gearbox also features a worm gear, which locks...

Overview The mini-motor gearbox kit from Tamiya makes it easy to get a small robot or plastic model moving. The kit includes one brushed DC motor and all the gears and parts to build any of the twelve possible gear ratio configurations:...

The Pololu dual high-power motor drivers are compact carriers for the VNH3SP30 and VNH2SP30 motor driver integrated circuits from ST. The board incorporates most of the components of the typical application diagram on page 8 of the...
