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...

This board is very similar to our DRV8833 dual motor driver carrier in operating voltage range and continuous current rating, but the DRV8835 has a lower minimum operating voltage, offers an extra control interface mode, and is 0.1″...

This semiconductor gas sensor detects the presence of Carbon Monoxide at concentrations from 10 to 1,000 ppm and combustible gas from 100 to 10,000 ppm. The sensor’s simple analog voltage interface requires only one analog input pin from...

The Pololu step-up/step-down voltage regulator S8V3A is a switching regulator (also called a switched-mode power supply (SMPS) or DC-to-DC converter) with a single-ended primary-inductor converter (SEPIC) topology. It takes an input...

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...

Overview This pancake bipolar stepping motor from Sanyo has a 1.8° step angle (200 steps/revolution). Each phase draws 1 A at 4.5 V, allowing for a holding torque of 1 kg-cm (14 oz-in). The motor has four color-coded wires terminated...

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...

These premium jumper wires, which are equivalent to our wires with pre-crimped terminalswith 1×1 crimp connector housings already attached, are great for making quick and easy prototyping connections. They are available in three...

This product has been replaced by newer version of Pololu #2995 . 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 one N-channel MOSFET per...

The two extremely springy tires in the Tamiya 70096 off-road tires set are about 50 mm in diameter and 30 mm wide. Use these if you want your robot to have a soft, air-cushioned ride across rough terrain. (Compatible with the Tamiya...

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...
