These are very bright LEDs. The LEDs are so bright that it hurts to look directly at them. Please take a look at the pictures to get an idea of the...

Electrolytic decoupling capacitors 100uF/25V. These capacitors are great transient/surge suppressors. Attach one between the power and ground of yo...

1/6th Watt, +/- 5% tolerance PTH resistors. Commonly used in breadboards and perf boards, these 10K resistors make excellent pull-ups, pull-down...

Piezo buzzers are used for making beeps, tones and alerts. This one is petite but loud! Drive it with 3-30V peak-to-peak square wave. To use, co...

Sometimes a simple analog control device can be the perfect tactile solution for your project, but they can be surprisingly hard to come by. Luc...

Breakaway header is like the duct tape of electronics, and this header is one better with extra long pins on both sides. This makes it great ...

This is a glass ferrule type fuse. It fits great with our 5mm fuse clips. The fuse is rated for 125VAC, up to 5A. Fuses are pretty simple, if more ...

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

These headers are made to work with the Teensy 3.2 and Teensy LC development boards. Each kit of headers makes your Teensy breadboard compatible...

Does your Arduino need to control a high voltage item, like a 12V LED strip, while needing to be powered as well? Do you want to avoid having multi...

The SparkFun WM8960 Audio Codec Breakout is a low-power, high-quality stereo codec with 1W Stereo Class D speaker drivers and headphone drivers. Th...

The SparkFun 5V Buck Regulator Breakout features the AP63357 from Diodes Inc., a 3.5A synchronous buck converter with a wide input voltage range of...

This is a simple 3-pin male SMD right angle header. Each pin can even be broken apart if you only need one or two pins instead of all three.The pin...

These blue flexible LED filament bulbs are perfect for creating unique lighting effects. With a length of 300mm, they provide plenty of light wh...

Make cables and wiring harnesses with ease using the best crimping pliers we've used. These especially light, ergonomic, precision-machined crimper...

Have you found yourself in a maze of twisty-turny knobs, all alike? These micro potentiometer (or rotary encoder) knobs offer a rainbow burst of co...

You just found the perfect I2C sensor, and you want to wire up two or three or more of them to your Arduino when you realize "Uh oh, this chip has ...

We dig the lil' rubber nubbin on the popular 75mm long 10KΩ slide potentiometer so much, we thought folks might like a pack of three for their own ...

Our favorite food when hacking on code or electronics is a hot bowl of noodles - and around NYC these are often called 'noods'! What we've got here...
