SK6812 / WS2812 NANO NeoPixel LEDs to solder onto your project
Such Neopixel LEDs are make with 3 internal LEDs (red, green, blue = rouge, vert, bleu) used to creates dazzle light effect. With this CMS product, you can create your own arrangement of RGB LEDs on a PCB by using the same LED package than used with NeoPixel Strips, Ring and Jowel.
This version of the LED package is a white package! Shipped into a bag of 10 LEDs that you can solder on your own board. We do also have lots of NeoPixels products on our shop!
When turned on, the LED produces a tremendous amount of light, enough to hurt your eyes. All LEDs can be controlled using an 8-bit PWM controller (8 x 3-channel = 24-bit to set the color).
A great productl for creating colorized lighting on your project! This nano size LED will allow you to create animated jewelry ring or light effect on very small/compact animatronic.
Such SMD (Surface Mounted Component) LEDs in package 2427 (2.4mm x 2.7mm) are not easy to solder. It requires accuracy and know-how to be soldered properly. Whereas 5050 package can still be soldered by makers, this 2427 package will requires adequate SMD skills.
NeoPixel LEDs use an 800 KHz protocol. The protocol requiring very strict time control during signal transmission. On Neopixels, the PWM frequency is 400Hz, which works well but noticeable when the LED is moving. For comparison, DotStars LEDs use a PWM frequency of 20 KHz, and no pixelation is noticeable when the LED is moved. (We recommend the use of DotStars LEDs if you have moving LEDs).
NeoPixels are LEDs containing a tiny microcontroller under the LEDs. Thanks to it, it is possible to fix the brightness of each of the Red / Green / Blue LEDs. Each Neopixel LED acts as a shift register, reads incoming data on the input pin, and sends the previously received data to the next LED (via the output pin). By sending a long string of data, it is possible to control an infinity of LEDs. The PWM controller included in each LED makes the NeoPixels fully autonomous. Once the brightness / color has been communicated to a NeoPixel, all communications can cease because the LED is autonomous and can display a steady colors without further communication from the microcontrôler.
We do have a very complete tutorial on the NeoPixels leds usage (wiring, power supply, consumption calculation, example code, etc.). Do not hesitate to read it! Please note, it will be necessary to use the NeoPixel library with RGB support. You will get weird results if you try to control these LEDs with the improper NeoPixel 'RGBW' library.
Adafruit's NeoPixel library supports both 'RGB' and 'RGBW' LEDs, but other libraries you might find on the Net may not.
