NeoPixel WS2812b 5v 2020 SMD Chip Addressable LED (10pcs)

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 very small - 2mm square. These Nano (2mm x 2mm) RGB LEDs are one third the size of mini 3535-sized NeoPixels and a sixth 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 ~12mA constant current drive, so the color will be very consistent even if the voltage varies, and no external choke resistors are required making your design minimal. Power the whole thing with 5VDC, and you're ready.

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.

Please note this is a surface mount part! It is possible to solder thin wires to the pads but it's designed for use on a SMD PCB. If you are not comfortable with hand-soldering SMD parts, rather check out other RGB LEDs such as the thru-hole ones or in pixels/strips.
