A Feather board without ambition is a Feather board without FeatherWings!This is the FeatherWing Proto - a prototyping add-on for all Feather boards. Using our Feather Stacking Headers or

These two Female Stacking Headers alone are, well, lonely. But pair them with any of our Feather boards and you're in business!What do they do? They stack. Put the headers through your Feather and then you can...

Hey, have you heard the good news? With Adafruit STEMMA boards you can easily and safely plug sensors and devices together, like this Adafruit STEMMA Speaker - Plug and Play Audio Amplifier. Like the name implies, it's got a class D audio amplifier on board, and our...

This cable will let you turn a JST PH 3-pin cable port into 3 individual wires with grippy mini alligator clips. We're carrying these to match up with any of our boards or breakouts with 3-pin 'STEMMA' connectors on them such as the 

This is a great battery-backed real time clock (RTC) that allows your microcontroller project to keep track of time even if it is reprogrammed, or if the power is lost. Perfect for data-logging, clock-building, time stamping, timers, and alarms, etc. Equipped...

These are the highest quality & capacity batteries, the same as shipped with the iCufflinks, iNecklace, Datalogging and GPS Shields, GPS HAT, etc. One battery per order (you'll want one battery per cufflink or pendant.)Brand may vary but all battery brands are verified...

What's a wearable project without LEDs? Our favorite part of the Flora platform is these tiny smart pixels. Designed specifically for wearables, these updated Flora NeoPixels have ultra-cool technology: these ultra-bright LEDs have a constant-current driver cooked right into the LED...

Low cost Lithium Polymer batteries have revolutionized electronics - they're thin, they're light, they can be regulated down to 3.3V and they're easy to charge. On your phone, there's a little image of a battery cell that tells you the percentage of charge - so you know when...

After months of searching, we finally have what we consider to be the ultimate conductive thread. It's thin, strong, smooth, and made completely of 316L stainless steel. Once you start working with this thread you'll quickly agree its optimal for any wearables work!This...

This 4-wire cable is 50mm / 1.9" long and fitted with JST SH female 4-pin connectors on both ends. Compared with the chunkier JST PH these are 1mm pitch instead of 2mm, but still have a nice latching feel, while being easy to insert and remove.

We use 2 pin JST PH connectors for all our battery packs, and if you want to put a board in series, like our LC709203F Stemma QT battery gauge, this cable will be very handy!Both ends have a JST PH 2mm pitch 2-pin plug. Between the...

Need a massive battery for your project? This lithium-ion pack is made of 3 balanced 2200mAh cells for a total of 6600mA capacity! The cells are connected in parallel and spot-welded to a protection circuit that provides over-voltage, under-voltage, and over-current protection.Each cell...

Perfect for bread-boarding, free wiring, etc. This box contains 6 spools of solid-core wire. These spools of solid-core wires are easily soldered to, keeps its shape pretty well when bent and is rated 80C and 300V (UL AWM style 1007). We...

Mighty needles, sew like the wind! This needle set is the only one you'll need for any sort of hand sewing, especially using our conductive thread and wearable electronics parts.Each pack contains 20 gold-eye sharps, with eye sizes ranging from #3 (1.75" long) to #9...

Known by engineers for making excellent quality tools & soldering irons! This is a genuine Hakko FX-888D with digital temperature control! We worked hard to get the best and a great price, these are not knock-offs. This iron is an upgrade to the...

If you want to make a kit you'll need some solder. This 0.1 lb (about 50 grams) spool is a good amount, not too much (like 1 lb spools) and not too little (like those little 'pocket clip' vials).This spool of solder contains approximately 0.6mm / .02" diameter in...

These are the finest wire strippers we have used, and if you have to do a lot of wiring, you will agree! They have soft rounded grips - very comfortable to use, and precision ground notches that do a perfect job every time. No more yanking or twisting to strip wires cleanly and quickly.

These are the best diagonal cutters, large super-comfortable grip to use and have strong nippers for perfect trimming of wires and leads. I've used my pair every day for years.
