Please note: you won't be able to use this kit as a TV tuner! The DVB-T standard is not used in North America. This products is used for various communication projects with RTL-SDR. More information here: rtl-sdr.com - About...

The "poor man's" accelerometer/motion sensor! These spring-vibration switches are high sensitivity non-directional vibration induced trigger switches. Inside is a very soft spring coiled around a long metal pin. When the switch is moved, the spring...

New! Version 3 comes with the latest module which has external antenna support and Pulse-Per-Second output Adafruit carries a few different GPS modules, but none that satisfied their every desire - that's why they designed this little GPS breakout board...

Pickup a copy of Getting Started with Adafruit Trinket and then hit the ground running with one of the most popular Trinket projects: the Trinket-Powered NeoPixel Goggle Kit Pack! This pack is perfect for somebody who is up for a little...

Make your own little LED strip arrangement with this stick of NeoPixel LEDs. Adafruit crammed 8 of the tiny 5050 (5mm x 5mm) smart RGB LEDs onto a PCB with mounting holes and a chainable design. Use only one microcontroller pin to control as many as you...

Need to measure something damp? This epoxy-coated precision 1% 10K thermistor is an inexpensive way to measure temperature in weather or liquids. The resistance in 25 °C is 10K (+- 1%). The resistance goes down as it gets warmer and goes up as it...

This is hot! Literally! Apply 5-12VDC and the stainless steel fibers in this heating fabric will warm up, creating a little heating pad. On one hand, it's just a gigantic resistor. On the other hand, it's flexible, light, and can be wrapped around a...

Transistors are powerful little electronic switches, and we really like these NPN transistors whenever we need to control medium-power electronics such as small motors, solenoids, or IR LEDs. We find them so handy, they come in a pack of 10! Each...

Listen up! This 1.1" (~30mm) diameter speaker is the perfect addition to any breadboard-based audio project where you need 8 Ohm impedance, and have 0.2W or less of power. The two pins are 15mm / 0.6" apart and fit perfectly in a breadboard or perfboard...

These nice switches are perfect for use with breadboard and perfboard projects. They have 0.1" spacing and snap in nicely into a solderless breadboard. They're easy to switch no matter what size fingers you have, but not so easy that they'll get flipped...

Light Sensitive Resistor GL5549

Move fluid safely from here to there with this very nice little pump. Unlike most liquid pumps, this is a peristaltic type - the pump squishes the silicone tubing that contains the liquid instead of impelling it directly. The upshot? The pump never...

Bring a little bit of Times Square into your home with this 16 x 32 RGB LED matrix panel. These panels are normally used to make video walls, but in New York you can see them on the sides of busses and bus stops, to display animations or short video...
