Has your “Check Engine Light” turned on in your car and you don’t know what could possibly be wrong? We get it, it’s a stressful situation that no one wants to be subjected to, and that’s why we created the SparkFun Car Diagnostics Kit!...

The ProtoSnap series is a new way to prototype your project without a breadboard. Everything is wired together on a single board, which makes it easy to explore the possibilities of the components before snapping them apart and building...

This is a time saving kit of jumper wires - cut, stripped, and pre-bent for your prototyping pleasure. Included with this kit are 14 various lengths of 22AWG wire - 2, 5, 7, 10, 12, 15, 17, 20, 22, 25, 50, 75, 100, and 125mm - 10 pieces...

Do not look into the light. You know you want to, but boy will you be sorry. 1W per channel, RGB High Power LEDs in one aluminum backed package. These LEDs will blow you away. Light them up then put a coffee cup over the LED to keep your...

Yes you read that correctly - 1 Farad capacitor. This small cap can be charged up and then slowly dissapated running an entire system for hours. Combine two in series for 0.5F/5V. Do not over voltage or reverse polarize these capacitors.

We know what you’re thinking, “What’s the big deal? Looks like an SD card…” Well this is no SD card! The Electric Imp is a WiFi enabled development platform powered by a Cortex-M3 processor core. “Really?” Yup. In essence, the Imp...

If you need to charge LiPo batteries, this simple charger will do just that, and do it fast! The SparkFun LiPo Charger Basic is stripped down of all features and just does one thing well - charge 3.7V LiPo cells at a rate of 500mA. It is...

The PowerCell board is a single cell LiPo boost converter (to 3.3V and 5V) and micro-USB charger in one. The board comes with a JST connector for a single cell LiPo battery, a micro-USB connector for the 5V charge input, and selectable...

This semiconductor gas sensor detects the presence of alcohol gas at concentrations from 0.04 mg/L to 4 mg/L, a range suitable for making a breathalyser. The sensor’s simple analog voltage interface requires only one analog input pin...

This is a super-high intensity Luxeon Rebel LED, warm white in color. These LEDs provide optimized light quality and efficiency to address a number of project needs, including LED illumination. These LEDs can be blindingly bright and...

This is a rippled wide lens from Carlco Optics. Combine this lens with our Luxeon Rebel LEDs to control where the light is going and how bright it is. This lens produces a rippled beam with a 24° beam angle. It has a diameter of 20mm....

This version of the QRE1113 breakout board features an easy-to-use analog output, which will vary depending on the amount of IR light reflected back to the sensor. This tiny board is perfect for line sensing applications and can be used...
