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. As they are pretty darn tiny, they might be a bit difficult to hand solder. SMT techniques with solder paste and hot air will work best here.

These Nano (2.4mm x 2.7mm) RGB LEDs are half the size of mini 3535-sized NeoPixels and a quarter of the size of standard 5050mm NeoPixels you may be used to seeing. They're the most compact way possible to integrate multiple bright LEDs to a design. The driver chip is inside the LED and has a constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors

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 any NeoPixels you can chain them together, the output of one leading into the input of another for near-infinitely long strips.

Comes in a strip of 10 pieces. If you order more than one strip, it will come as multiple strips of 10, not one long strip.
