It's blue! It's thin (0.8mm)! It's the Arduino Pro Mini! SparkFun's minimal design approach to Arduino. This is a 5V Arduino running the 16MHz bootloader. Arduino Pro Mini does not come with connectors populated so that you can solder in...

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...

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...

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....

The TTS256 is an 8-bit microprocessor programmed with letter-to-sound rules. This built-in algorithm allows for the automatic real-time translation of English ASCII characters into allophone addresses compatible with the Magnevation...

The uLog is a tiny analog datalogger. Central to the logger is an ATtiny24 mated with an AT45DB161D 16Mbit flash IC. Sampling at 50Hz, it’ll log 3 channels of 10-bit ADC for about 2 hours before the memory fills up. Very stripped down...
