Lithium-ion polymer (also known as 'lipo' or 'lipoly') batteries are thin, light, and powerful. The output ranges from 4.2V when completely charged to 3.7V. This battery has a capacity of 350mAh for a total of about 1.3 Wh.  The batteries come...

If you're looking for the most compact li'l color display for a Raspberry Pi B+, Pi 2, & Pi 3 (most likely a Pi Zero) project, this might be just the thing you need! The Adafruit Mini PiTFT - 135x240 Color TFT Add-on for...

Need some really bright LEDs? We are big fans of these white LEDs. They are very bright and have about 20degree LED beam. They go easily into a breadboard and will add that extra zing to your project. Pack of 25 white LEDs 5mm diameter Cool white...

PIR sensors are used to detect motion from pets/humanoids from about 5 meters away (possibly works on zombies, not guaranteed). This sensor is much smaller than most PIR modules, which makes it great for unobtrusive projects. It's also fully-contained -...

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...

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...

This power jack is designed to fit 2.1mm power plugs snugly and securely. Perfect for adding a power connector to your project. We went for the more expensive "thin pin" type which snap into breadboards or perfboards. They will work where "thick pin"...

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 rotary encoder is the best of the best, its a high quality 24-pulse encoder, with detents and a nice feel. It is panel mountable for placement in a box, or you can plug it into a breadboard (just cut/bend the two mechanical side tabs.) We also...

This is a basic, classic Adafruit Raspberry Pi Camera Board Enclosure with a black base and a clear top. The case is as minimal as it gets, coming in just two pieces of polycarbonate that snap snugly together. This case will keep...

Attaching NeoPixel strips to your costume can be a struggle as the flexible PCBs can crack when bent too much. So how to add little dots of color? Use these stranded NeoPixel dots! They're very small, so they're easy to embed into any structure, costume,...

Stack multiple plates, breakouts etc onto your Raspberry Pi Model B+ with this custom-made extra-tall and extra-long 2x20 female header. The female header part has extra spaces to make it 23.5 mm tall: when placed on your Pi, a PCB will clear the...

This 'shorty' 2x20 header is great for a slim connection to your Raspberry Pi model A+ or B+, it's basically the  through-hole version of the SMT GPIO Header for Raspberry Pi HAT - 2x20 Short Female Header. This header is for super-slim...

That new Raspberry Pi® Model B+ computer you just got has a row of 2x20 pin headers soldered on - those are the GPIO (general purpose input/output) pins and for those of us who like to hack electronics, they are where the real fun is. By programming...

Here's a snazzy accessory for your Raspberry Pi Zero or Zero W, a color-coded 2x20 header! This Color Coded Header takes the mystery out of your Raspberry Pi's 2x20 pinout. No longer will you stare in confusion at all 40 pins, trying to count...

Hey Mr. DJ! Turn up that Raspberry Pi mix to the max with this cute 3W Stereo Amplifier Bonnet for Raspberry Pi. (It's not big enough to be an official HAT, so Adafruit called it a bonnet, you see?) It's the exact same size as a Raspberry...

This is the assembled version of the Pi T-Cobbler Plus.  It only works with the Raspberry Pi Model Zero, A+, B+, Pi 2, Pi 3 & Pi 4! (Any Pi with 2x20 connector)The Raspberry Pi B+ and Pi 2 has landed on the Maker World like a 40-GPIO...

Round and round and round they go! 16 ultra bright smart LED NeoPixels are arranged in a circle with 1.75" (44.5mm) outer diameter. The rings are 'chainable' - connect the output pin of one to the input pin of another. Use only one microcontroller pin to...

It's the Circuit Playground Express Base Kit! It provides the few things you'll need to get started with the new Circuit Playground Express. This version of Circuit Playground is super powered, and will work with Microsoft...

Hit the ground running (and printing!) with this starter pack that includes a thermal printer and all the extras and save a few dollars while you're at it. Includes A mini thermal receipt printer - with cables and plastic mounting shims A roll...
