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 are just mind-bogglingly small. They are a mere 2mm x 2mm (way smaller than APA102-5050 SMD RGB), which makes them pretty darn tiny so they might be a bit difficult to hand solder.

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.

There are 2 Versions, one is 6 Feet version, and the other one is 8 feet version
