These 0.1" female header strips are commonly used as low-cost connectors for custom-made cables or perforated prototyping PCBs. The standard spacing is the same as on most solderless breadboards and matches 0.1" male header strips . Our...

These universal mounting hubs are designed to work with most 6 mm diameter shafts , including round shafts and “D” shafts. Each of the two included hubs has six mounting holes for M3 screws (not included), letting you mount custom wheels...

This compact sensor is a great way to quickly detect the presence of nearby objects. As long as the sensor is enabled, it takes continuous distance measurements and uses a single digital output to indicate if it detects an object within...

This current sensor is a carrier board or breakout board for Broadcom’s ACHS-7121/7122/7123/7124/7125 Hall effect-based, electrically isolated current sensors; we therefore recommend careful reading of the ACHS-7121/7122/7123 datasheet...

Our Micro Metal Gearmotor family consists of tiny brushed DC metal gearmotors with nitride-hardened martensitic stainless steel gears in a wide range of gear ratios, motor windings, brushes, and encoder configurations: Micro Metal...

The U3V40Fx family of boost (step-up) voltage regulators are high-efficiency synchronous switching regulators that generate higher output voltages from input voltages as low as 1.3 V. (Note: minimum start-up voltage is 2.7 V; see the...

This board is a 3-channel time-of-flight proximity and distance sensor module based on the OPT3101 IC from Texas Instruments. Unlike conventional IR sensors that use the intensity of reflected light to estimate the distance to an object,...

The Pololu USB AVR Programmer v2.1 is a compact, low-cost in-system programmer (ISP) for AVR microcontrollers from Atmel (now a part of Microchip). The programmer provides an interface for transferring a compiled AVR program from your...

The Pololu High-Power Stepper Motor Driver 36v8 combines the DRV8711 stepper motor driver IC from Texas Instruments with external MOSFETs to enable control of large bipolar stepper motors at operating voltages from 8 V to 50 V. The...

This set contains components for adding a tracked drive system to a small robot or vehicle. It consists of: Two silicone tracks Two ABS drive sprockets Two ABS idler sprockets Two M3 shoulder bolts with a 5mm threaded portion Two M3...
