16X16 RGB LED Panel light,led screen apa102,led display flexible led dot matrix

1.There's a new square design LED matrix in

iPixel LED!
16*16 Pixel APA102C LEDs
use a 2-wire SPI,it can push data much faster
than with the WS2812B 800 KHz
protocol and there's no specific timing
required. it's also have much higher
PWM refresh rates.
2.This SMD 5050 LEDs is GRB color sequence ,not RGB sequence !!!
with an embedded microcontroller inside the LED. You can set the color/brightness of each
LED to 24-bit color (8 bits each red green and blue). Each LED acts like a shift register, reading
incoming color data on the input pins, and then shifting the previous color data out on the
output pin. By sending a long string of data, you can control an unlimited LEDs
3.These LEDs have 2 wires (input and output) for clock and one data pin.
Because the clock and data is seperated, you can use any microcontroller or microprocessor,
including Arduino, Raspberry Pi, BeagleBone, Propeller to control it
PWM rate. You only have to set the 24-bit color data for each pixel LED once, and then the
LED+built-in-chip will handle the PWMing of the red, green and blue.
On our WS2812B Matrix, this PWM rate happens 400 Hz, which works well but is noticably
at lower brightnesses and if the strip is moving in any way. have a 20 KHz PWM rate, even if
you set any color or animation, there is no pixelation
4.The Matrix is made of flexible PCB material,Non-waterproof ,for indoor use only, 2 Ounce
copper PCB and black color you can also connect each matrix to together to make them as
large as a P10 LED screen, make sure gave them enough Power , each matrix 256 pcs LEDs
