APA102-2020 LED SMD

APA102-2020 LED SMD

APA102-2020 SMD LED is a new type of APA102 integrated led for three channels RGB color emitting.
It has very little size with 2.0mm*2.0*0.9mm,which has much more advantage for the smaller than 5050 led with 5.0*5.0mm.
and many new applications will be available for the tiny size.
apa102 2020 also use the APA102 as the driver IC to control the color dimming.
Also high brightness too,for each apa102-2020 led is 0.1W.
It can be widely used in apa102 2020 digital rgb led strips,apa102 2020 dotstar,also apa102 led pixels,and the full color led display.
Kindly check the link for more detail:

SK6812 LED STRIP

Nowadays, NEW Build IN led SK6812 LED is come out , and it have been a big competitor for WS2812B , So our factory not only have WS2812B LED STRIP , But also develop SK6812 LED STRIP , it can be 30leds 60leds 72leds 144leds per meter.
there are some parameter of sk6812 led strip

Main Application Field:
● Full color LED string light, LED full color module, LED super hard and soft lights,
LED guardrail tube, LED appearance / scene lighting
● LED point light, LED pixel screen, LED shaped screen, a variety of electronic products,
electrical equipment etc..

Mechanical Product Size (unit mm):
● Top SMD internal integrated high quality external control line serial cascade constant current IC;
● control circuit and the RGB chip in SMD 5050 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;
●data transmission frequency up to 800Kbps, when the refresh rate of 30 frames per second,
a cascade of not less than 1024;
● built-in powerpolarity protection module, powerpolarity will not damage.

APA102 5050 RGB LED with Integrated Driver Chip


This item is sometimes sold under the made up name 'Dotstar' - but this is just a name. We are factory sell directly: www.sfleds.com
Make your own smart LED arrangement with this tiny APA102 5050 RGB LED with Integrated Driver Chip (5mm x 5mm), easy to solder and the most compact way possible to integrate multiple bright LEDs to a design.
These LEDs use genertic 2-wire SPI and are able to transfer data much faster than previous versions (800 KHz protocol) like the WS2812S RGB LEDs. They also have much higher PWM refresh rates, and improved Persistence-of-Vision (POV) with less flickering, particularly at low brightness levels.
The APA102 LEDs are 5050-sized with an embedded microcontroller inside the LED. You can set the colour/brightness of each LED to 24-bit colour (8 bits each red green and blue). Each LED acts like a shift register, reading incoming colour data on the input pins, and then shifting the previous colour data out on the output pin. By sending a long string of data, you can control an infinite number of LEDs, just tack on more or cut off unwanted LEDs at the end. The PWM is built into each LED-chip so once you set the colour you can stop talking to the strip and it will continue to PWM all the LEDs for you.
The APA102 has a high PWM rate. You only have to set the 24-bit colour data for each pixel LED once, and then the LED+built-in-chip will handle the PWMing of the red, green and blue. They have a 20 KHz PWM rate, so even when moving the strip around, you won't see the pixelation, the color blending is very smooth.

Adafruit DotStar LED Strip - APA102 Warm White - 30 LED 5m - ~3000K

Move over NeoPixels, there's a new LED strip in town! These fancy new DotStar LED strips are a great upgrade for people who have loved and used NeoPixel strips for a few years but want something even better. DotStar LEDs use generic 2-wire SPI, so you can push data much faster than with the NeoPixel 800 KHz protocol and there's no specific timing required. They also have much higher PWM refresh rates, so  you can do Persistence-of-Vision (POV) and have less flickering, particularly at low brightness levels.
Make your own smart Warm White LED arrangement with the same integrated LED driver that is used in our new fancy DotStar strips.  Unlit, the color resembles an egg yolk. Lit up these are insanely bright (like ow my eye hurts) and can be controlled with 24 bit high-frequency PWM. The phosphor helps diffuse the 3 white dies inside together for a very bright but consistant light, compared to what you get by trying to mix RGB to make white (which never quite looks right)
However, unlike NeoPixels, these LEDs have 2 wires (input and output) for sending data - one clock pin and one data pin. That means you need two pins, not one, to control DotStars. Because the clock and data is separated, you can use any processor speed or type to control these strips, and you don't have to worry about being careful with the timing. Hardware SPI support is handy but not required. This makes them excellent for use with any microcontroller or microprocessor, including Arduino, Raspberry Pi, BeagleBone, Propeller, SparkCore, and any 'raw' microcontrollers/microprocessors. It's very easy to port the library, and you can send data to the pixels at up to 32MHz clock rate!
They're also a great upgrade for people who have loved and used NeoPixels for a few years but want to use the same kind of technology for monochromatic lighting. DotStar LEDs use generic 2-wire SPI, so you can push data much faster than with the NeoPixel 800 KHz protocol and there's no specific timing required. They also have much higher PWM refresh rates, so you can do Persistence-of-Vision (POV) and have less flickering, particularly at low brightness levels.
This is the 30 LED-per-meter version of our DotStar strips, on white flex PCB. 
The strip is made of flexible PCB material, and comes with a weatherproof sheathing. You can cut this stuff pretty easily with wire cutters, there are cut-lines every 1 LED. Solder to the 0.1" copper pads and you're good to go. Of course, you can also connect strips together to make them longer, just watch how much current you need! You must use a 5V DC power supply to power these strips, do not use higher than 6V or you can destroy the entire strip
These strips come in 5 meter reels with a 4-pin JST SM connector on each end. 
TECHNICAL DETAILS
  • The manufacturer of the APA102C smart LED used in this strip used to be GRB order, and has changed in 2015 to have BRG color order. This means if you are using our DotStar library, you'll need to change the initialization to tell it which you are using. Check the tutorial for details on how to do this! The LED colors are otherwise identical, you just have to pipe the data to it in a slightly different order.
    • Width of Strip: 12mm / 0.5"
    • Thickness of Strip: 4mm / 0.2"
    • 30 LEDs per meter
    • Pixel Pitch: 33mm / 1.3"
    • Operating Temperature: -40°C - 40°C
    • Storage Temperature: -10°C - 50°C

    • Single LED: 5mm x 5mm / 0.2" x 0.2"
    • We don't have any more specifics about this particular LED other than it is ~3000K color temp and seems to have 3 white LEDs in place of the normal Red/Green/Blue
