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...

If you want to get some sound out of your project but have a tight space budget, this is a good way to do it. This 0.25W, 8Ohm speaker is only 40mm in diameter and just over 4mm thick, the same kind you might find in one of those...

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...
