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 not only plug them into a solderless breadboard, but you could attach circuitry...

Upgrade a project that uses a photocell with the GA1A12S202 analog light sensor. Like a CdS photo-cell, the sensor does not require a microcontroller, the analog voltage output increases with the amount of light shining on the sensor face. This sensor has a lot of improvements that make it better for nearly any project. The...

A simple 2-pin connector soldered onto a breadboard-friendly breakout. This is compatible with the "JST PH 2-pin" connector. Mates perfectly with all our Adafruit 1-cell LiPoly and LiIon batteries as well as our 6V coin cell holder and 3xAAA battery pack. We also have simple JST pigtails that mate with this connector.

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 proper level shifting chip, not resistors: fewer problems,...

A Feather board without ambition is a Feather board without FeatherWings! This is the NeoPixel FeatherWing, a 4x8 RGB LED Add-on For All Feather Boards! Using our Feather Stacking Headers or Feather Female Headers you can connect a FeatherWing on top or bottom of your Feather board and make your Feather board strut like...

What's a wearable project without LEDs? Our favourite 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 package! The pixels are chainable - so you only need 1 pin/wire to...

This breakout board will solve all your power-monitoring problems. Instead of struggling with two multimeters, you can just use the handy INA219B chip on this breakout to measure both the high side voltage and DC current draw over I2C with 1% precision. Most current-measuring devices such as our current panel...

Punch in your secret key into this numeric matrix keypad. This keypad has 12 buttons, arranged in a telephone-line 3x4 grid. It's made of a thin, flexible membrane material with an adhesive backing (just remove the paper) so you can attach it to nearly anything. The keys are connected into a matrix, so...

What is better than smart RGB LEDs? Smart RGB+White LEDs! These NeoPixels now have 4 LEDs in them (red, green, blue and white) for excellent lighting effects. Make your own smart RGBW LED arrangement with the same integrated LED driver that is used in our NeoPixel LED strips. The NeoPixel is...

Punch in your secret key into this numeric membrane keypad. This keypad has 4 buttons, and since every key has its own wire line, no matrix code is required - just treat these like everyday switches. The membrane is soft and has a removable paper backing to expose a strong adhesive so you can...

These displays are small, only about 1" diagonal, but very readable due to the high contrast of an OLED display. This display is made of 128x32 individual white OLED pixels, each one is turned on or off by the controller chip. Because the display makes its own light, no backlight...

Itsy Bitsy Teenie Weenie Mini NeoPixel RGB LED-inis! Make your own smart LED arrangement with the same integrated LED that is used in our NeoPixel strip and pixels! These MINI (3.5mm x 3.5mm) RGB LEDs are fairly easy to solder and are half the size of the standard 5x5mm NeoPixels you...

We love our black and white monochrome displays but we also like to dabble with some colour now and then. Our 1.27" colour OLED displays are perfect when you need a small display with vivid, high-contrast 16-bit colour. The visible portion of the OLED measures 1.27" diagonal and contains 128x96 RGB...

We love our black and white monochrome displays but we also like to dabble with some colour now and then. Our big 1.5" colour OLED displays are perfect when you need a small display with vivid, high-contrast 16-bit colour. The visible portion of the OLED measures 1.5" diagonal and contains 128x128...

PowerBoost is the perfect power supply for your portable project! This little DC/DC boost converter module can run from 1.8V batteries or higher, and convert that voltage to 5.2V DC for running your 5V projects. Like our popular 5V 1A USB wall adapter, we tweaked the output to be 5.2V...

"How could something so simple be so useful?" We heard once that in the 4th millennium B.C. some guy asked the person who invented the wheel that question. The person who invented the wheel's answer, we were told, was something like "well it's not actually that simple - it required engineering...
