The fastest PWM 27KHZ Frequency speed SK9822-A led

Nowadays, There are more and more different types of smart led in the market ,In order to make our products lead in the market, our company has invested a lot of research and development.Then our company have different kinds of smart led .Currenty , a new LED come out , it is SK9822-A LED,the fastest frequency speed LED in the Market .


Normally our standard is SK9822-A 5050 RGB. and we have many of those standard led chip in stock , we also can custom make another different Color.

How fast it can reach sk9822-A LED? The maximum PWM frequency can reach 27KHZ input . it have Data and Clock signal input and output , which make the signal transfer more stable ,then it can be Anti-signal interference without using capacitor.

APA102 PWM frequency 20KHZ,SK9822 PWM frequency 4.7KHZ.

If you don’t need the led chip in such high frequency speed , but with data and clock signal ,then you can use our SK9822, if you only need data signal , then you can use SK6812, if you want smaller smd , then you can use 2020 ,1515. if you want double data and 12V, you can use our 12V SK6813.

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.

DC12V addressable WS2815 LED

WS2815 LED is DC12v dual signal,signal break-point continuous transmission.


General description
WS2815 is an intelligent control LED light source that the control circuit and RGB chip are integrated in a package of 5050 components. Its internal includes intelligent digital port data latch and signal reshaping amplification drive circuit.
Dual-signal wires version, signal break-point continuous transmission. Any pixel’s failure won't affect signal transfer and total emitting effect.
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. Every pixel adopts auto-reshaping transmit technology, making the pixel cascade numbers are not limited to the signal transmission, only relate to the speed of signal transmission.
The BIN receives the data signal, and then compare the data with the DIN side after phagocytosis of 24bit data, if DIN do NOT receive the signal, then switching to BIN for receiving the input signal, which ensure that any the IC's damage does not affect the signal cascade transmission and make the BIN in state of receiving signal until restart after power-off.
Refresh Frequency updates to 2KHz, Low Frame Frequency and no Flicker appear in HD Video Camera.
RESET time>280μs, it won’t cause wrong reset while interruption, it supports the lower frequency and inexpensive MCU.
Integrated circuit chips enable the circuit control simpler, neater and more reliable while NO extra components needed.

Features and Benefits
The control circuit and RGB chip are integrated in a 5050 components, to form an external control pixel.
12V DC power supply, can effectively reduce the operating current of the pixel LED, and decrease the voltage-drop of the PCB, this is to advance the consistency of the mixed lights for long-distance transmission.
Using the built-in signal reshaping circuit to achieve the signal waveform shaping, and no distortion of waveform of signal takes place.
The gray levels of each pixel are of 256 levels, which achieves ¨256*256*256=16777216〃 full-color display, and the refresh frequency reaches to 2KHz.
Serial cascade interface, data receiving and decoding depend on just one signal line.
Dual-signal wires version, signal break-point continuous transmission.
Any two point the distance more than 5M transmission signal without any increase circuit.
When the refresh rate is 30fps, cascade numbers is at least 1024 pixels.
Data transmitting at speeds of up to 800Kbps.
Good color consistency reliability, high cost-effective.
