A mini class D with AGC and I2C control? Yes please! This incredibly small stereo amplifier is surprisingly powerful. It is able to deliver 2 x 2.8W channels into 4 ohm impedance speakers (@ 10% THD)...

This here is a 10 pack of the classic 1N4001 power blocking diode. These are good for reverse polarity protection (put it between your DC power jack and circuitry to avoid a negative-voltage that...

Need some really bright LEDs? We are big fans of these clear green LEDs, in fact we use them exclusively in our kits. They are very bright and have about 20degree LED beam. They go easily into a...

The PN532 is the most popular NFC chip, and is what is embedded in pretty much every phone or device that does NFC. It can pretty much do it all, such as read and write to tags and cards, communicate...

Get the most out of your regulators, transistors and other TO-220 packaged chips by clipping on a heat-sink. Your transistor or regulator may advertise it can handle high currents but when multiplied...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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,...

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...

Need a lot of 5V power? This switching supply gives a clean regulated 5V output at up to 4 Amps (4000mA). 110 or 240 input, so it works in any country. The plugs are "US 2-prong" style so you may...
