For a long time we\'ve had small 7-segment displays and *huge *7-segment displays, but now we finally have something in between. These 20mm 4-digit...

LEDs - those blinky things. A must have for power indication, pin status, opto-electronic sensors, and fun blinky displays. This is a very basi...

It\'s the end of the world, and you need a button to press. This is it. A 100mm diameter (outside diameter) dome illuminated push button comes with...

This DC Blower really moves some air! Pulling about 1Amp @ 12VDC, this blower is rated at 16CFM (although it seems like more to us). We\'ve used th...

These panel-mounting rocker switches have built-in indicator lights to let you know when your switch is engaged. They mount into a 20.2mm diameter ...

These plastic LED holders have a slick chrome finish and make it possible to panel-mount your indicator lights for a clean look. These LED holders ...

This is the kind of 1/4\" stereo jack you might find in home stereos and PA systems. Switched contacts allow you to detect whether or not there is ...

This is a simple 3.5mm TRS stereo audio jack with a screw-on plastic shroud. These are great for projects that plug into headphone jacks. Stereo pl...

Check out these big 10mm through-hole LEDs! The opaque epoxy package causes these LEDs to have a soft, diffuse glow. **Features:** * 3.0-3.4VDC F...

This 1024 pulse per rotation rotary encoder outputs [gray code](http://en.wikipedia.org/wiki/Gray_code) which you can interpret using a microcontro...

This through-hole speaker is great for projects where you need something that sounds better than a piezo buzzer but don\'t have room for a full-blo...

VS1063 is an easy-to-use, versatile encoder, decoder and codec for a multitude of audio formats. They can be hard to get hold of but we\'ve got the...

The MMA8452Q is a smart low-power, three-axis, capacitive MEMS accelerometer with 12 bits of resolution. This accelerometer is packed with embedded...

Resistors are a good thing, in fact, they\'re actually crucial in a lot of circuit designs. The only problem seems to be that resistors disappear i...

This is a basic, 4-digit 7-segment display - white in color. It has a common anode. The display features one decimal point per digit, and individua...

Schottky diodes are known for their low forward voltage drop and a very fast switching action. This 1A 40V Schottky diode is ideal for use with mot...

These are massive single pole - double throw (SPDT) sealed relays. This means that when current is applied to the coil it throws a simple changeove...

These are the same RGB LEDs that were used for the old WS2801 breakout board. They\'re great when you need a lot of color from not a lot of board s...

A simple SMD slide switch. Perfect for when you need access to a setting or a power switch from the edge of a PCB buried deep within a project. **...
