Overview This current sensor is a carrier board or breakout board for Allegro’s ACS714LLCTR-30A-T Hall effect-based linear current sensor; we therefore recommend careful reading of the ACS714 datasheet (678k pdf) before using this...

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 This current sensor is a carrier board or breakout board for Allegro’s ACS711KLCTR-12AB-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...

This is a rechargeable 6.0 V NiMH battery pack with a capacity of 2200 mAh. The pack consists of five AA cells in a single row and a 4" lead terminated by a “JR”-style connector. Connector This battery pack comes with 4" leads terminated...

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...
