It’s like an Xacto knife, only better. We use these extensively when working with PCBs. These small knives work well for cutting traces, scraping ground pours, and guiding hair-like wires into their proper place. Excel knife comes with...

This a breakout board for the SMD connector for the Nintendo DS touch screen. 4-pin right angle ZIF connector at 0.5 mm pitch broken out to 4 0.1 inch spaced headers.

This is a 4-wire analog touch screen originally designed for the Nintendo DS. Add this touch screen to any LCD you want! Readings are taken by putting 5V across two of the pins and doing an analog to digital conversion on the other two...

This is 30 feet of conductive thread spun from stainless steel fiber and wound on a plastic bobbin. Use it to sew up all of your e-textile projects. This small bobbin is a great way to get into wearable electronics without the upfront...

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...
