WS2812 2020 SMD Micro Digital RGB LEDs, 100 Pack
Small size, Big function! 5mA/16mA operating current per channel.
We have them straight off the factory floor in full reels of 4,500 LEDs packed in the aluminum envelop. If you are the person who needs that many, we highly recommend to buy them by reels to keep moisture to the minimum. Ordering 45 packs (4,500 LEDs) at a time, you will get a whole reel.
- Buy 10 for $9.95 each and save 29%
- Buy 50 for $9.45 each and save 32%
- Buy 100 for $8.95 each and save 36%
- Buy 500 for $8.45 each and save 39%
We all love WS2812 serial LEDs because they are so easy to control as a full color LED. But the previous version dimensions are big, the package size are 5050, and high current, now this 2020 version is changed, the package size is only 2020, only ⅛ of the 5050 size, and low power consuming, which makes it easy to embed into small dimension PCB projects.
WS2812-2020 is an intelligent control LED light source, its exterior adopts the latest MOLDING packaging technology, the control circuit and RGB chips are integrated in a package of 2020 component. Its internal includes intelligent digital port data latch and signal reshaping amplification drive circuit. Also include a precision internal oscillator and a voltage programmable constant current control part, effectively ensuring the pixel point light color height consistent.
The data transfer protocol use single NZR communication mode. After the pixel power-on reset, the DIN port receive data from controller, the first pixel collect initial 24bit data then sent to the internal data latch, the other data which reshaping by the internal signal reshaping amplification circuit sent to the next cascade pixel through the DO port. After transmission for each pixel, the signal to reduce 24bit. pixel adopt auto reshaping transmit technology, making the pixel cascade number is not limited the signal transmission, only depend on the speed of signal transmission.
RESET time>280μs , it won't cause wrong reset while interruption, it supports the lower frequency and inexpensive MCU.
Refresh Frequency updates to 2KHz, Low Frame Frequency and No Flicker appear in HD Video Camera, it improve excellent display effect.
LED with low driving voltage, environmental protection and energy saving, high brightness, large scattering angle, good consistency, low power, long life and other advantages. The control chip integrated in LED above becoming more simple circuit, small volume, convenient installation.
