This is a stereo amplifier kit designed to make use of the STA540 power amplifier IC. Once this kit is completed you have a fully functional, two-channel audio amplifier, complete with a standby switch, volume control and indicator LEDs....

Bare Paint is the first non-toxic electrically conductive paint available to consumers today! This unique child-friendly material is designed for people of all ages to explore and learn about electronics with an inclusive, easy-to-use...

This high discharge LiPo is a great way to power any R/C, robotic, or portable project. This is an excellent choice for anything that requires a small battery with a lot of punch. The voltage is low enough not to tax your regulating...

This motor driver board, originally designed by Dagu for their Rover 5 platform, is ideal for any small 4-wheel drive robotic vehicle. With four motor outputs, four encoder inputs and current sensing for each motor, it’s a must-have when...

In secure embedded systems, you often need to authenticate messages or connected devices but many microcontrollers aren't set up for the necessary cryptography. That's where the Atmel ATSHA204 comes in. The Atmel ATSHA204 is an optimized...

A SparkFun original Lithium Polymer charger. This little black box charges single cell lithium polymer batteries with a max rate of 1A. The charge output is via a 2-pin screw terminal. Top pin is ground, bottom pin is charge pin. Based...

The SparkFun EL Sequencer is a board that contains an Arduino-compatible microcontroller, and circuitry for controlling up to eight strands of electroluminescent wire . EL wire is flexible plastic cord that glows brightly when...

We’ve heard you, and made a number of improvements to our EL Shield. The new version adds zero-crossing optoisolated triacs for noise-free operation and full isolation between the AC and DC sides, and includes a 1.5A adjustable linear...

This is the newest revision of our FTDI Basic. We now use a SMD 6-pin header on the bottom, which makes it smaller and more compact. Functionality has remained the same. This is a basic breakout board for the FTDI FT232RL USB to serial...

A very powerful 5mW green laser. Fun, but don’t point in anyone’s eyes. These units include two solder points for permanent on. The trim-pot adjusts the output power. We were able to push the current up to about 400mA where things...

These LED string lights are a great way to add light to any project with little to no soldering required. The insulated strings come in 10m lengths with one red LED every 10cm for a total of 100 LED’s, all you have to do is add 3-3.4V...

It's the end of the world, and you need a button to press. This is it. A blue economy grade 100mm diameter (outside diameter) dome illuminated push button comes with an LED, securing nut and a long life horizontal microswitch. Be aware...
