Use these controllers as the brain for your next project. You can connect them to your computer and program them in various languages including BASIC, C, and C++.
Prototype your electronic circuits for cheap with our affordable, reusable breadboards.
Protect your circuits from accidental flipping of power supply connections with these reverse voltage protection modules. They operate from 4 V to 60 V and provide protection from negative voltages down to -60 V.
Printed circuit boards with breadboard-like groups of connected pads for quickly making semi-permanent versions of your circuits.
Cleanly connect wires and modules to each other with our various connectors.
Stranded 26 AWG wires with male or female connectors for use with 0.1″ (2.54 mm) headers and breadboards. Available in a variety of lengths and colors.
Premium stranded wires with male or female terminals for use with 0.1″ (2.54 mm) headers and breadboards. Available in a variety of lengths and colors. Works with crimp connector housings to make custom cables.
Bulk stranded hook-up wire in a variety of gauges and colors. The convenient mini spools are all filled, so the wire lengths range from 40 to 100 feet (12 to 30 meters), depending on thickness.
Pre-cut wires that make your prototype breadboard circuits quick to assemble, neat, and reliable.
An assortment of switches, buttons, and relays that can serve as user-interface elements, tactile sensors, power switches, and more.
The Pololu RP5/Rover 5 expansion plates are cut from 1/8″ acrylic in a variety of colors and make it easy to mount components on the Rover 5 tracked chassis. They can also be used without a chassis as universal mounting plates for your project electronics.
Ensure your project gets the voltage it needs with these voltage regulator boards and wall-adapter power supplies.
These breadboard-compatible modules are alternatives to bulky power switches. Since the main current does not flow through the mechanical switch, a variety of small, low-power switches can be used to control a lot of power. Additional inputs enable control of these switches from a microcontroller output or other digital signal.
An assortment of unidirectional and bidirectional current sensors. They offer a very low-resistance current path and electrical isolation between the current source and the measuring circuit. You can use these sensors to monitor your motor current, detect current spikes, or even to make inexpensive current probes for your oscilloscope.
Pre-programmed motion control chips, microcontrollers, and more!

This breakout board for Texas Instruments’s TPS2113A autoswitching power multiplexer allows you to select which of two power sources is connected to a load while blocking reverse current into either of the sources. It has an adjustable current limit that can be set as high as 2 A and an adjustable switching threshold. Each input power rail on the multiplexer can be supplied with 2.8 V to 5.5 V, and the board also breaks out a USB Micro-B connector that can be used to supply one of the rails.
