These super-tiny surface-mount LEDs are a great way to add loads of small yet bright colorful dots to your project. They're incredibly compact, being half the size of mini 3535-sized NeoPixels and a quarter of the standard 5050mm NeoPixels. Hand soldering them can be a bit tricky due to their small size, so using SMT techniques with solder paste and hot air is recommended. Each LED has a built-in driver chip with constant current drive, ensuring consistent color even when the voltage changes, and no need for external choke resistors. Inside, there are red, green, and blue LEDs controlled by a tiny chip that takes 24-bit color data via clock and data inputs and handles all the PWM control. You can easily chain them together for long strips. The product comes in strips of 10 pieces, and if you order multiple strips, you'll get separate 10-piece strips. Note that this is a surface mount part designed for SMD PCBs. If you're not confident with hand soldering SMD parts, check out our other RGB LEDs like thru-hole ones or in pixels/strips. We also have a tutorial on wiring, power usage calculations, and example code for usage.
Using these NeoPixel Nano 2427 RGB LEDs is easy. First, decide where you want to place them in your project. Since they're surface mount parts, it's best to use SMT techniques with solder paste and hot air for soldering. If you're not experienced with this, it might be a bit challenging, so take your time. Once soldered, you can connect them to your power source and control system. The LEDs are controlled by a tiny chip that takes 24-bit color data, so you just need to'set' the color data once. You can chain multiple LEDs together by connecting the output of one to the input of another. As for power usage, refer to our tutorial for detailed calculations. When it comes to maintenance, keep them away from moisture and excessive heat. If you need more information on wiring or example code for usage, check out our tutorial.
