Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference. The MAX31855K does everything for you, and can be easily interfaced with any microcontroller, even one...

Your power supply problems just got SOLVED! This little circuit board may look tiny but inside is a high efficiency DC/DC step-down converter which can output up to 3 Amp at 5V without the need of...

Adafruit seesaw is a near-universal converter framework which allows you to add add and extend hardware support to any I2C-capable microcontroller or microcomputer. Instead of getting separate I2C...

Sew a little sparkle into your wearable project with an Adafruit LED Sequin. These are the kid-sister to the popular Flora NeoPixel, they only show a single color and they don't have digital control,...

"You see, wire telegraph is a kind of a very, very long cat.  You pull his tail in New York and his head is meowing in Los Angeles.  Do you understand this? And radio operates exactly the...

This breakout board is the simplest way to create a project with a single "momentary" capacitive touch sensor. No microcontroller is required here - just power with 1.8 to 5.5VDC and touch the pad to...

Round and round and round they go! 24 ultra bright smart LED NeoPixels are arranged in a circle with 2.6" (66mm) outer diameter. The rings are 'chainable' - connect the output pin of one to the input...

RGB Pixels are digitally-controllable lights you can set to any color, or animate. Each RGB LED and controller chip is molded into a 'dot' of silicone. The dots are weatherproof and rugged. There are...

Infrared LEDs are used for remote controls (they're the little LED in the part you point at your TV) and 'night-vision' cameras, and these little blue guys are high powered ones! They are 940nm...

These 4-wire cables are 15cm long and come as a set, one side has a JST SM type connector plug on the end. The other side has a matching JST SM type receptacle connector. They are good for whenever...

The IS31FL3731 will let you get back to that classic LED matrix look, with a nice upgrade! This I2C LED driver chip has the ability to PWM each individual LED in a 16x9 grid so you can have...

IR sensor tuned to 38KHz, perfect for receiving commands from a TV remote control. Runs at 3V to 5V so it's great for any microcontroller. To use, connect pin 3 (all the way to the right) to 5V...

For advanced DotStar LED fans, Adafruit now has a bendable, Flexible 16x16 Dotstar LED Matrix! Control all 256 ultra-bright LEDs using only two microcontroller pins, set each LED as you wish to...

Squeeze once to turn on, squeeze again to turn off! This clicky switch makes a great power switch or mode toggler. We like this switch because it's easy to embed in a seam for easily powering up/off...

Make your own USB connections without slicing apart a USB cable and soldering those thin wires inside. These DIY "USB shells" are available in USB A plug, micro B, mini B and USB A socket. Each...

These chrome-plated metal buttons are rugged and look real good while doing it! Simply drill a 16mm hole into any material up to 1/2" thick and you can fit these in place, there's even a rubber...

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 datalogging,...

By popular demand, we now have these buttons with a full color RGB LED ring light! These chrome-plated metal buttons are rugged, but certainly not lacking in flair. Simply drill a 16mm hole into...

Connect to those pesky 0.5mm pitch connectors that you may run across with an FPC stick. Adafruit designed this for use in house, to quickly connect to 50pin 0.5mm pitch flex cables they need to test...
