This type of buck (step-down) voltage regulator is commonly used in the RC hobby industry, where it is called a “Battery Elimination Circuit” (BEC). It can convert a higher voltage, such as from a motor battery, to a lower 5 V level for...

This board is a compact (0.5″ × 0.9″) breakout board for ST’s L3GD20 three-axis digital-output gyroscope; we therefore recommend careful reading of the L3GD20 datasheet (2MB pdf) before using this product. The L3GD20 is a great IC, but...

Overview These sensors are a great way to quickly detect the presence of nearby objects. It consists of a Sharp GP2Y0D805, GP2Y0D810, or GP2Y0D815 sensor module installed on our tiny carrier board for these sensors, which includes all of...

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 hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 280 mA at 7.4 V, allowing for a holding torque of 650 g-cm (9 oz-in). The motor has four color-coded wires terminated with bare leads:...

Overview Pololu dual MC33926 motor driver shield for Arduino. This motor driver shield and its corresponding Arduino library make it easy to control two bidirectional, brushed DC motors with an Arduino or compatible board, such as the...

The mbed NXP LPC1768 development board from ARM enables quick and easy creation of high-performance prototypes. Based on the powerful NXP LPC1768 Cortex-M3 processor, which runs at 96 MHz and offers 512 KB flash and 32 KB SRAM, the...

These royal blue T-shirts are available in mediumadult sizes. The front shows a fully assembled Zumo robot with mounted Arduino Uno , and the word “Push.” written underneath. The back features the Pololu slogan, “Engage Your Brain”. Made...

The qik 2s9v1 is Pololu’s second-generation dual serial motor controller. The compact module allows any microcontroller or computer with a serial port (external RS-232 level converter required) or USB-to-serial adapter to easily drive...

Allegro’s A4990 is a dual H-bridge motor driver IC that can be used for bidirectional control of two brushed DC motors at 6 to 32 V. It can supply up to 0.7 A continuously to each motor channel, and the current control feature of the...

These adjustable boost (step-up) voltage regulators generate higher output voltages from input voltages as low as 2.9 V. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) and have a...
