The Pololu 15 Amp high-power motor driver is a discrete MOSFET H-bridge designed to drive one DC brushed motor. The H-bridge is made up of one N-channel MOSFET per leg, and most of the board’s performance is determined by these MOSFETs (the rest of the board contains the circuitry to take user inputs and control the MOSFETs). The board supports a wide 5.5 to 24 V voltage range and is efficient enough to deliver a continuous 15 A without a heat sink, or 21 A with a heat sink.

Side-looking Infrared Emitters and IR Detectors. These simple devices operate at 940nm and work well for generic IR systems including remote control and touch-less object sensing. Using a simple ADC on any microcontroller will allow variable readings to be collected from the detector. The emitter is driven up to 50mA with a current limiting resistor as with any LED device. The detect is a NPN transistor that is biased by incoming IR light.

A SparkFun original Lithium Polymer charger. This little black box charges single cell lithium polymer batteries with a max rate of 1A. This works well with our 5V/1A regulated supply. The charge output is via a 2-pin screw terminal. Top pin is ground, bottom pin is charge pin. Based on the popular Microchip part MCP73843-410.

These lipped Rubber Rings have an inner diameter of 4.65", a width of 1/8", and a sturdy rubber sidewall. These rings can be used as a replacement for Precision Disk Wheels or can wrap around the outside edge of another flat disc to make the ring a simple tire.

The Arduino Yún is a microcontroller board based on the ATmega32u4 (datasheet) and the Atheros AR9331. The Atheros processor supports a Linux distribution based on OpenWrt named Linino OS.

The mbed boards are a series of ARM microcontroller development boards designed for rapid prototyping and this is breakout makes it easy to get up and running with your mbed LPC1768 module. The new application board has been designed to enable the maximum number of potential experiments and projects, with the minimum footprint. And this thing is small.

An oscilloscope is an awesome tool to have around the shop. Unfortunately, most scopes take up quite a bit of bench space and they’re not very portable. The DSO Nano v3, on the other hand, is a 32bit digital storage oscilloscope that fits in the palm of your hand! Based on ARM -M3, it’s equipped with a 320x240 color display, internal 2MB storage, USB port and recharging function. It’s compact, simple to operate and perfect for everything from the test bench to field work.

Ever wish your project could just speak up and tell you what’s going on? Why not give it a voice? The Emic-2 Text-to-Speech module makes it really easy to give voice to your embedded projects.

Want to free your pcDuino from the oppression of wired networking? This USB Wifi dongle has been tested to work with the pcDuino, simply plug it into the USB port and you’re ready to connect to a nearby wireless network!

The pcDuino AV Kit includes everything you need to get your pcDuino powered, networked and connected to an HDMI enabled TV or monitor. If you don’t happen to have all of these cables laying around, this is the easiest way to get up and running with your pcDuino.

This is a high-quality color CMOS camera module. Power the CM-32 module, hook up any display, monitor, or LCD screen with an RCA input and get vivid color video at 728x488 resolution. Module is easily mountable and has a wide operating voltage (6V to 20V). Comes with high quality optics, all the on board circuitry to output RCA signal, and cable harness.

This is a pan/tilt bracket designed specifically to work with the robotic claw MKII that we sell. It comes with all of the hardware you need to connect it to the claw and even includes the ‘tilt’ control servo. Panning can be controlled by attaching a medium servo to the bracket milled into the base of the arm; it’s the same size servo that fits the robotic claw, you can find it in the related products below).

The µLCD-32PTU is a compact Intelligent Display Module from 4D Systems packed with plenty of features, ready to become the GUI for your project, and capable of being an interface controller for a number of applications.

When you’re working with e-textiles, you have a tendency to collect a lot of small parts: LilyPad boards, bobbins, needles, the tools of the trade. Why not pick up a sturdy little box to keep your bits and pieces off the floor? This LilyPad branded box is made from rigid cardboard printed with a fancy tone-on-tone pattern and LilyPad logo. There are even magnetic closures embedded in the lid.

This is a fairly large, 80x80x15mm fan. The fan has a DC brushless motor, with an operating voltage of 12V, and is rated at 180mA. Keeping the temperature down in your project can often be a necessity, and this fan can definitely help.

This is the same product as the Mr. Roboto Kit. The difference is this version comes in fancy clamshell packaging meant for our distributors that need it. Regular customers are welcome to order, but we want to limit the amount of extra packaging finding its way into the trash heap.

Button, button, Who’s got the button? You do… if you have our Button Kit on hand! This collection of common buttons and switches will ensure that you’ve got the right button for the job. There are 14 switches total of 5 different varieties that we use in projects every day here at SparkFun.

These crimp connectors can be used to terminate our 4-wire conductive ribbon. Simply insert the end of the ribbon into the connector and press it closed. The “teeth” inside the connector will crimp around the conductors and break them out to 4 standard 0.1" spaced pin headers!

This conductive ribbon is a great way to wire your e-textile projects without running hundreds of stitches all over the place! There are 4 insulated silver coated conductors in this flexible, polyester fabric ribbon. The conductors can’t be soldered to, but we do carry crimp-on connectors that you can use to terminate the ribbon cable with pin-headers. Check out the related items below for connectors.

This is the same product as our EasyDriver Stepper Motor Driver. The difference is this version comes in fancy clamshell packaging meant for our distributors that need it. Regular customers are welcome to order, but we want to limit the amount of extra packaging finding its way into the trash heap.
