NeoPixel Addressable RGB LEDs - Slim Round 3.2mm x 1.0mm 10 pack

These super-small and slim surface-mount NeoPixel LEDs are a great way to add lots of tiny yet bright colorful dots to your project. Measuring just 3.2mm x 1.0mm x 1.48mm, they can be soldered in multiple ways: flat on a PCB, reverse-mounted using top pads and a PCB cutout, or at a right angle. Due to their tiny size, hand - soldering is difficult; SMT techniques with solder paste and hot air work best. The built - in driver chip has a ~12mA constant current drive, ensuring consistent color even with voltage variations. No external choke resistors are needed, simplifying your design. Power it with 5VDC and you're set. Each LED contains red, green, and blue elements, controlled by a small chip that takes 24 - bit color data via clock and data inputs and handles PWM control. You only need to'set' the color data once. Like other NeoPixels, you can chain them together for long strips. Since they're very small and have pads underneath, they're not for hand - soldering. If you prefer hand - soldering, check out 5050 sized or through - hole NeoPixel LEDs. This pack comes with 10 individual LEDs. We also have a slim flat version. Our detailed NeoPixel Uberguide has all the info you need for using NeoPixels of any shape and size, including ready - to - go libraries and example code for various Arduino models.

Using these NeoPixel LEDs is easy. First, power the LEDs with 5VDC. You can then set the color data just once, and the built - in chip will take care of the rest. When it comes to soldering, because these LEDs are so small, it's best to use SMT techniques with solder paste and hot air. Avoid trying to hand - solder them as it can be really tricky. You can connect multiple LEDs together to create long strips. Just make sure the output of one LED goes into the input of the next. For maintenance, keep them away from extreme temperatures and moisture.
