Pipe audio in or out of your project with this very handy breadboard-friendly audio jack. It's a stereo jack with disconnect-switches on Left and Right channels as well as a center ground pin. You can use any 3.5mm stereo cable with this jack. The pins...

You can now create a dazzling display with your Raspberry Pi Model A+/B+/Pi 2 with the Adafruit RGB Matrix HAT. This HAT plugs into your Pi and makes it super easy to control RGB matrices such as those we stock in the shop and create a colorful scrolling...

If the product is out of stock - please consider the alternative product. This is a pre-wired and waterproofed version of the DS18B20 sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to...

Control the flow of fluid using the flow of electrons! This liquid valve would make a great addition to your robotic gardening, aquarium, or pool project. There are two 1/2" (Nominal NPS) outlets. Normally, the valve is closed. When 12VDC is applied to...

Need to add analog inputs? This chip will add 8 channels of 10-bit analog input to your microcontroller or microcomputer project. It's super easy to use, and uses SPI so only 4 pins are required. We chose this chip as a great accompaniment to the...

The classic 'third hand tool,' as seen on every desk! We have one next to our Panavise jr, they complement each other well. This tool is good for holding small PCBs and wires for tinning or soldering to parts. Every part can rotate around in any way...

Add a power switch to any USB-powered project simply by plugging this between the USB power port and the USB cable. This is the most useful thing you never knew you needed! You'll want to pick up a bunch for your electronic projects. Comes with a USB A...

Not just a simple breakout board, this microSD adapter goes the extra mile - designed for ease of use. Onboard 5v->3v regulator provides 150mA for power-hungry cards 3v level shifting means you can use this with ease on either 3v or 5v systems Uses a...

This cable will let you swap out the stock 150mm long flex cable from a Raspberry Pi Camera (either 'classic' or 'NoIR' type) for a different size. Works great, just carefully open the connector on the Pi and slip this one in. This cable is 300mm...

Because the Arduino (and Basic Stamp) are 5V devices, and most modern sensors, displays, flash cards and modes are 3.3V-only, many makers find that they need to perform level shifting/conversion to protect the 3.3V device from 5V. We do have some other...

These are our favorite trimpots, perfect for breadboarding and prototyping. They have a long grippy adjustment knob and with 0.1" spacing they plug into breadboards or perfboards with ease. This is the same pot that comes with our character LCDs and...

This prototyping shield is the best out there (well, we think so, at least), and now is even better with Version R3 - updated for the most compatibility with just about all the Arduinos! It works with UNO, Mega, Leonardo, NG, Diecimila, Duemilanove,...

Nothing makes a project harder to maintain than a lot of loose wiring. That's why we like to use terminal blocks whenever making PCB-to-Wire connections. These particular 3.5mm terminal blocks are our favorite: big enough for a range of wire gauges, easy...

After a long day out harvesting in the terminal block fields, we've returned with a veritable bounty of these very nice and compact 2.54mm/0.1" terminal blocks in a variety of sizes. Our harvest of terminal blocks is great news since nothing makes a...

This potentiometer is a two-in-one, good in a breadboard or with a panel. Its a fairly standard linear taper 10K ohm potentiometer, with a grippy shaft. Its smooth and easy to turn, but not so loose that it will shift on its own. We like this one because...

Oh say can you see By the knob's early light... Sorry - we thought that was clever.  And while it wasn't really, this potentiometer knob definitely is.  It's a 'soft touch' T18 knob that works great with our Panel Mount 10K potentiometers...

This is just the clear lid of the Raspberry Pi Model A+ case.  Check out our A+ base here. This enclosure was designed by Mike Doell.  It's made of ultra-durable, super-glossy polycarbonate, and is both good looking and tough enough...

Add an ear to your project with this well-designed electret microphone amplifier. This fully assembled and tested board comes with a 20-20KHz electret microphone soldered on. For the amplification, we use the Maxim MAX4466, an op-amp specifically...

Connect this to that without soldering using these handy mini alligator clip test leads. 15" cables with alligator clip on each end, color coded. You get 12 pieces in 6 colors. Strong and grippy, these always come in handy! We often use these in...

The Raspberry Pi is a wonderful little computer, but one thing it isn't very good at is controlling DC Servo Motors - these motors need very specific and repetitive timing pulses to set the position. Instead of asking the Pi Linux kernel to send these...
