These incredibly small surface-mount LEDs are an easy way to add a lot of very tiny (but bright!) colorful dots to your project. They’re mini versions of our digital DotStart strips and matrices with full chainable 2-wire control. They are just mind-bogglingly small. They are a mere 2mm x 2mm (way smaller than APA102-5050-RGB), which makes them pretty darn bitty, so they might be a little cumbersome to hand solder. SMT techniques with solder paste and hot air will work best here.
There are three LEDs inside, red, green, and blue. The RGB LEDs are controlled by a tiny chip that takes a 24-bit color level via the clock and data in and then does all the PWM control for you. So you just ‘set’ the color data once. Like DotStars (and the similar NeoPixels) you can chain them together, the output of one leading into the input of another for near-infinitely long strips.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
