Look, just bolt this to your ceiling fan already - we know that's the first thing you thought of! OK, so you already know what DotStar LEDs are - those digitally controllable LEDs that have two data wires and higher refresh rates for than NeoPixels. You can control them with any microcontroller since the timing on the data lines isn't particular, and you can use an SPI peripheral to send data pretty fast. DotStars come in the classic...

Move over NeoPixels, there's a new LED strip in town! These fancy new DotStar LED strips are a great upgrade for people who have loved and used NeoPixel strips for a few years but want something even better. DotStar LEDs use generic 2-wire SPI, so you can push data much faster than with the NeoPixel 800 KHz protocol and there's no specific timing required. They also have much higher PWM refresh rates, so  you can do...

Blinded by the light? Tell "The Boss" not to worry, especially with this ultra thin Side Light NeoPixel LED PCB Bar ! Fancy side light LED strips are a great alternative for folks who have loved and used Adafruit NeoPixel strips for a few years but want gorgeous, glowy light emitting at 120 degrees. We already have flexible LEDs, so these bars are more on the rigid/firm spectrum of LED strips. They're made...

Bullseye! This disk is chock full of *255* Dotstar LEDs and it's BRIGHT! The Dotstar RGB LED Disk is sprinkled with digitally-addressable LEDs, comes on a white PCB with two 4 pin JST-SM connectors already soldered to it so it's ready to rock straight out of the box. These are the same integrated LEDs that are used in our new fancy DotStar strips. This tiny 5050 (5mm x 5mm) SMD LED is the most compact way possible to integrate...

This is a custom made pack for the University of Virginia.  It contains all the gear needed for Web and Mobile Systems class - CS4720. Since it's a pretty cool pack, and seems like a great course, we've decided to also sell it in our store.  Here's a description of the course to get an idea of what they're working on and check out the class website for more information.  Our course mixes web...

RGB Pixels are digitally-controllable lights you can set to any color, or animate. Each plastic PVC 'pixel bar' contains 3 RGB LEDs and a controller chip soldered to a PCB. The pixel is then 'flooded' with epoxy to make it waterproof. These are fairly large pixels but they have a lot of nice mounting options, such as two plastic flanges on the ends with 0.15"/4mm diameter holes and also some sticky foam tape on the back for...

This Mini Power Meter with Voltage, Current, Watts, mAh & mWh Display (whew that is a mouth-full) is a lot like the USB In-Line Voltage and Current Meter we carry but can  be used with a wide range of voltages (not just USB connections). Measure the working voltage and current output for any project with this really fancy power meter. This power meter has a small LCD display that shows off voltage, watts, amps, and mAH and...

This tiny coin cell battery holder is ideal for small portable or wearable projects. It holds two 20mm coin cells (2032 are the most popular size) in series to generate 6V nominal. (If you want only 3V, we suggest sticking a crumpled piece of tin foil in one of the slots.) 20mm coin cells are popular as they are used in keychain lights, so they are easy to get, and fairly low cost. They tend to have about 220mAh capacity so this holder would...

Wouldn't it be cool to drive a tiny OLED display, read a color sensor, or even just flash some LEDs directly from your computer?  Sure you can program an Arduino or Trinket to talk to these devices and your computer, but why can't your computer just talk to those devices and sensors itself?  Well, now your computer can talk to devices using the Adafruit MCP2221A breakout board! What can the MCP2221 chip do?...

Listen up! This set of two 2.8" x 1.2" speakers are the perfect addition to any audio project where you need 4 ohm impedance and 3W or less of power. We particularly like these speakers as they are small and enclosed for good audio volume and quality. The pair have a handy SPK input cable to add audio to your displays (the connectors are similar to the JST-PH series which is ~2.0mm spacing). We're specifically carrying...

When 0.1" is too big, and JST PH's too chunky, the ultra-slim "PicoBlade" is a reliable alternative. These are only 1.25mm pitch, but have a nice clicky connection. This cable is nice and long, 200mm in fact. It's got both small form factor (won't take up a lot of real estate on your PCB) and friction lock to make easy-breezy connections to your HalloWing or anything else with a 1.25mm PicoBlade connection.
