The GP2Y0A21 Sharp distance sensor is a great way to add obstacle avoidance or motion sensing to your robot or any other project. With a detection range of 4" to 32" and an analog voltage indicating the distance, this sensor is very easy...

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 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 ball caster kit includes a black ABS housing, a 1/2" diameter plastic 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 included...

This ball caster can be used as a replacement 3pi robot part or as a general-purpose ball caster. When mounted through a hole in a chassis that uses our micro metal gearmotors and our 32×7mm wheels , as on the 3pi, this ball caster is...

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...
