EL wire, or electroluminescent wire, is a flexible wire coated in phosphor. Apply the appropriate voltage and it lights up! It looks a lot like a thin flexible neon tube. They come in many bright colors (check below for other colors) and...

The SparkFun VoiceBox Shield can be mounted on top of your Arduino board to give it access to all of the capabilities of the SpeakJet voice and sound synthesizer. The Voice Box Shield uses the SpeakJet chip to convert serial commands...

The Intel® Edison is an ultra small computing platform that will change the way you look at embedded electronics. Each Edison is packed with a huge amount of tech goodies into a tiny package while still providing the same robust strength...

An adjustable potentiometer can open up many interesting user interfaces. Turn the pot and the resistance changes. Connect VCC to an outer pin, GND to the other, and the center pin will have a voltage that varies from 0 to VCC depending...

Face it, if you keep this up your workbench is going to turn into a galaxy of small parts with no place for anything and nothing in its place. Okay, so maybe that just happens to some of us, but everyone could use a little organization...

The SparkFun BlackBerry Trackballer Breakout gives you easy access to a trackball which measures up, down, left, and right movements, clicks on the board, as well as adding a bit of flair to your project with four built-in LEDs. The...

This is the LilyPad Arduino Simple Board. It’s controlled by an ATmega328 with the Arduino bootloader. It has fewer pins than the LilyPad Arduino Main Board, a built in power supply socket, and an on/off switch. Any of our LiPo batteries...

The LilyPad SimpleSnap is a new, easy way to create e-textiles projects with LilyPad that are modular and can be disassembled or broken down, it’s also a great way to prototype! The SimpleSnap board is similar to the LilyPad Simple...

It’s blue! It’s skinny! It’s the Arduino Pro! SparkFun’s minimal design approach to Arduino. This is a 3.3V Arduino running the 8MHz bootloader. Because the system voltage for this board is lower than other Arduino development boards, it...

It’s blue! It’s skinny! It’s the Arduino Pro! SparkFun’s minimal design approach to Arduino. This is a 5V Arduino running the 16MHz bootloader in a super-sleek form factor that will fit easily into your next small project. Arduino Pro...

Two pin, compact surface mount connector. We really like the solid locking feeling and high current rating on these small connectors. We use these all the time as battery connectors.
