Prototype your electronic circuits for cheap with our affordable, reusable breadboards.

Stranded 26-awg wires with male or female terminations for use with 0.1″ (2.54 mm) headers and breadboards. Available in a variety of lengths and in 10 different 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 in 10 different colors. Works with crimp connector housings to make custom cables.

Pre-cut wires that make your prototype breadboard circuits quick to assemble, neat, and reliable.

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.

Printed circuit boards with breadboard-like groups of connected pads for quickly making semi-permanent versions of your circuits.

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.

An assortment of unidirectional and bidirectional Hall effect-based 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.

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.

Price: $3.95
Quantity:

This breakout board for Fairchild’s FPF1320 acts as a power multiplexer, allowing you to select which of two power sources is connected to a load while blocking reverse current into either of the sources. It handles up to 1.5 A of current at 1.5 V to 5.5 V and also breaks out a USB Micro-B connector that can be used to supply one of the input power rails.

Pololu item #: 2592
Price: $1.49
Quantity:

This simple board breaks out all five pins of a USB Micro-B connector to a 0.1″ pin spacing that is compatible with standard perfboards, solderless breadboards, and 0.1" connectors.

Pololu item #: 2593
Price: $1.49
Quantity:

This simple board breaks out all five pins of a USB Mini-B connector to a 0.1″ pin spacing that is compatible with standard perfboards, solderless breadboards, and 0.1" connectors.

Pololu item #: 2597

This simple board breaks out the pins of a microSD card connector to a 0.1″ pin spacing that is compatible with standard perfboards, solderless breadboards, and 0.1" connectors.

Pololu item #: 2595
Price: $2.50
Quantity:

This tiny logic level shifter features four bi-directional channels, allowing for safe and easy communication between devices operating at different logic levels. It can convert signals as low as 1.5 V to as high as 18 V and vice versa, and its four channels are enough to support most common bidirectional and unidirectional digital interfaces, including I²C, SPI, and asynchronous TTL serial.
