The D24V10Fx family of step-down voltage regulators features the Intersil ISL85410 1A synchronous buck regulator and generates lower output voltages from input voltages as high as 36 V. They are switching regulators (also called...

The Pololu step-up/step-down voltage regulator S7V8A is a switching regulator(also called a switched-mode power supply (SMPS) or DC-to-DC converter) that uses a buck-boost topology. It takes an input voltage from 2.7 V to 11.8 V and...

This current sensor is a carrier board or breakout board for Allegro’s ACS711KEXLT-15AB-T Hall effect-based linear current sensor with overcurrent fault output; we therefore recommend careful reading of the ACS711 datasheet (533k pdf)...

These two large (120mm-diameter) wheels from Dagu Electronics match those on the Dagu Wild Thumper chassis and can be used as replacement parts or for custom robots that need to traverse complex, rugged terrain. The black tires are made...

Description These 20 mm long aluminum adapters convert a 6 mm diameter shaft to a 12 mm hex shaft that is compatible with many common hobby RC wheels. The set includes two adapters, two M4 screws for securing wheels to the adapters, four...

This add-on board enables a Raspberry Pi B+, A+, or Pi 2 to drive a pair of brushed DC motors. Its dual MC33926 motor drivers operate from 5 V to 28 V and can deliver a continuous 3 A (5 A peak) per motor. The default pin mappings make...

The VL6180X from ST Microelectronics is a sensor that combines proximity ranging and ambient light level measurement capabilities into a single package. This board is a carrier for the VL6180X, so we recommend careful reading of the...

The Pololu Pushbutton Power Switch is a compact, solid-state power switch that features built-in reverse-voltage protection and is controlled by a momentary pushbutton: one push turns on power and another push turns it off. This is a...

This gearmotor is a miniature high-power brushed DC motor with a 29.86:1 metal gearbox. It has a cross section of 10 × 12 mm, and the D-shaped gearbox output shaft is 9 mm long and 3 mm in diameter. This version also has a 4.5 × 1 mm...

Overview This current sensor is a carrier board or breakout board for Allegro’s ACS711KEXLT-31AB-T Hall effect-based linear current sensor with overcurrent fault output; we therefore recommend careful reading of the ACS711 datasheet...

Overview This pancake bipolar stepping motor from Sanyo has a 1.8° step angle (200 steps/revolution). Each phase draws 1 A at 5.9 V, allowing for a holding torque of 2.2 kg-cm (30 oz-in). The motor has four color-coded wires terminated...

The m3pi robot is a fully-assembled, upgraded version of our popular 3pi robot. It consists of a 3pi robot base connected to an assembled m3pi expansion board that simplifies augmenting your robot’s capabilities with an mbed development...
