SK6812 led is popular on the market,in order to meet different customers needs,we produce different sizes sk6812,like sk6812 5050,sk6812 mini 3535,sk6812 2020,sk6805 2427 and sk6805 1515.
SK6812 have two types current sk6812 and sk6805,sk6812 is 12mA current,sk6805 is 5mA current.
SK6812 series have the same protocol,and using different place.

12V SK6812 LED,12V SK6813 LED Come Out
Everyone knows 5V SK6812,5V SK6813 LED,those 5v led chip have a higher voltage drop when you power them more than 5m.even you power them 5m 60leds per meter led strip,when you make them light white color,the tail color consistency will be not good.So we design 2 new smart led strip,one is 12v sk6812 led chip,the other is 12v sk6813 led chip.
What's the different from those 2 new version?
For 12v sk6812 led,it has the same protocol as 5v sk6812 led,it's SPI signal,the signal is series connection,when one led signal connection is bad,then behind led will not work correctly.
For 12v sk6813 led,it has the same protocol as 5v sk6813 led,it's SPI signal too,but it have 2 signals wire,which means one led signal is broken,the behind led can still work,unless 2 adjacent led is bad.

What's the difference of SK6805-2427 SMD LED and SK6812 2020 LED
Everyone knows SK6812 5050 SMD,SK6812 3535 SMD,SK6812 2020 SMD LED,very little people know 2427 smd led,now there is SK6805-2427 smd led.
SK6812 2020 LED size is 2.0*2.0mm.
SK6805-2427 LED size is 2.4*2.7mm,it'widely used in digital led screen,digital led strip and some specializing size projects.
What's the difference of SK6805-2427 SMD LED and SK6812 2020 LED?just is the size and current,sk6805 is 5mA current version,sk6812 is 12mA current version.They have same protocol,can be controlled by same controller.

Product Overview :
SK6805MICRO is a smart LED control circuit and light emitting circuit in one controlled LED source, which has the shape of a 2427 LED chip. Each lighting element is a pixel, and the intensities of the pixels are contained within the intelligent digital interface input. The output is driven by patented PWM technology, which effectively guarantees high consistency of the color of the pixels. The control circuit consists of a signal shaping amplification circuit, a built-in constant current circuit, and a high precision RC oscillator. The data protocol being used is unipolar RZ communication mode. The 24-bit data is transmitted from the controller to DIN of the first element, and if it is accepted it is extracted pixel to pixel. After an internal data latch, the remaining data is passed through the internal amplification circuit and sent out on the DO port to the remaining pixels. The pixel is reset after the end of DIN. Using automatic shaping forwarding technology makes the number of cascaded pixels without signal transmission only limited by signal transmission speed. The LED has a low driving voltage (which allows for environmental protection and energy saving), high brightness, scattering angle, good consistency, low power, and long life. The control circuit is integrated in the LED above.
Description:
● Top SMD internal integrated high quality external control line serial cascade constant current IC;
● control circuit and the RGB chip in SMD 2427 components, to form a complete control of pixel, color mixing uniformity and consistency;
●built-in data shaping circuit, a pixel signal is received after wave shaping and output waveform distortion will not guarantee a line;
●The built-in power on reset and reset circuit, the power does not work;
●gray level adjusting circuit (256 level gray scale adjustable);
● red drive special treatment, color balance;
● line data transmission;
● plastic forward strengthening technology, the transmission distance between two points over 10M;
●Using a typical data transmission frequency of 800 Kbps, when the refresh rate of 30 frames per sec.
