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 space. Features: Viewing angle: 120 degrees Red: (640nm) @ 250mcd Green: (525nm) @ 880mcd...

You may recognize the WS2801from our addressable RGB LED strips. These 3-channel constant current LED drivers are great for controlling chains of RGB LEDs. The IC is controlled by a 2-wire serial control scheme that allows multiple ICs...

This is a sensitive gate TRIAC (also known as a thyristor) with a 200V blocking voltage in a bread board friendly TO-92 package. Use a triac to control an AC load (like EL wire, small incandescent lamps, etc) from a DC source (like the...

These headers are made to work with the Arduino Main Board, Arduino Pro, and the Arduino Mega. They are the perfect height for clearing the USB-B connector and great for stacking multiple shields. This kit includes 4 headers (2 8-pin and...

Surface transducers give you the awesome power to turn almost any surface into a speaker. Much like our larger surface transducer, this is essentially just a speaker except instead of a cone, the coil is attached to a pad that conducts...

Surface transducers give you the awesome power to turn almost any surface into a speaker. They’re essentially just a speaker except instead of a cone, the coil is attached to a pad that conducts the vibration into whatever you press it...

Testing surface-mount components with standard test leads is anything but easy. Everyone has their own method: some people tackle it with teamwork and have a friend (or grad student) hold the probes, some people have adapted a sort of...

The TLC5940 is a 16 channel PWM unit with 12 bit duty cycle control (0-4095), 6 bit current limit control (0-63), and a daisy chainable serial interface. This breakout board is a good way to take full advantage of this useful IC. All 16...

The RPI-1031 tilt sensor is capable of sensing a change in orientation in four different directions: forward, back, left or right. This breakout board makes it easier to incorporate the RPI-1031 in your next project by breaking the...

A simple slide potentiometer can go a long way. Rated at 10kOhm and 0.5W. Comes with solder tab connections. The taper profile for this slide can be found in the datasheet below labeled “0B”

This is a breakout board for Blackberry Trackball. The four spindles on the trackball have a tiny circular magnet the end; each of these are paired with an SMD hall effect sensor, which are used to measure up, down, left and right...

Faster, cheaper, smaller, better, right? The SN754410 Quad Half H-Bridge is just that. Capable of driving high voltage motors using TTL 5V logic levels, the SN754410 can drive 4.5V up to 36V at 1A continuous output current! Please see...
