Deprecation Warning: The Gemma bit-bang USB technique it uses doesn't work as well as it did in 2014, many modern computers won't work well. So while we still carry the Gemma so that people can maintain some older projects, we no longer recommend it.

Be the belle of the ball with the NeoPixel Jewel!  We fit seven of our tiny 5050 (5mm x 5mm) smart RGB LEDs onto a beautiful, round PCB with mounting holes and a chainable design to create what we think is our most elegant (and evening-wear appropriate) NeoPixel board...

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 ~100mAh for a total of about 0.4 Wh. If you need a larger battery,

Oh so adorable, this is the tiniest little lipo charger, so handy you can keep it any project box! Its also easy to use. Simply plug in the gold plated contacts into any USB port and a 3.7V/4.2V lithium polymer or lithium ion rechargeable battery into the JST plug on the other end. There are...

Oooh it's so soft! And that beautiful pattern! If you have to have visible cables then you might as well have the nicest fabric bound cable with a eye-catching snake-like pattern.  That's why we now carry this standard A to micro-B USB cable for USB 1.1 or 2.0....

Silicone-sheathing wire is super-flexible and soft, and it's also strong! Able to handle up to 200°C and up to 600V, it will do when PVC covered wire wimps out. We like this wire for being extremely supple and flexible, so it is great for wearables or projects where the wire-harness...

Simple needlenose pliers for twisting, pulling and pliering your project.

What do you get when you combine an Adafruit classic with geniuses at Arduino? The Arduino GEMMA! It's a tiny wearable platform board with a lot of might in a 1" diameter package. Powered by a Attiny85 and programmable with an Arduino IDE over USB, you'll be able to...

Get started with Adafruit GEMMA with this lovely starter kit! Included is everything you need to make a basic project. There's a GEMMA M0, four sewable bright RGB pixels, a battery holder (coin cell batteries not included), 2-ply conductive thread, alligator clips to help you test...

Go interactive with sensors and Adafruit GEMMA with this lovely starter kit! Included is everything you need to make a basic sensing project (or two). There's a GEMMA board, four sewable bright RGB pixels, a motion sensor, a switch, a light sensor, a piezo, a rechargeable battery and...

Make your wearables glow with the GEMMA sequin pack! This GEMMA parts pack makes it easy to add light to your wearables. It comes with thread, needles, a holder for 2 x CR2032 coin cell batteries, a GEMMA sewable microcontroller, and warm white Adafruit LED Sequins. This pack...
