16x16pixel square apa102 led flexible 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 request about 8A.These matrix comes in 1pcs per bag, on the back side, soldered a pair of 4-pin JST SM connector, it's makes easy to link to next matrix

you can see it very clearly from below pictures, it's SMD5050 LED chip, and APA102 ic

built-in, it with 16 x16, 256 pixels each matrix, and black PCB, 4wires, ip20

We also have other APA102 flexible led matrix, with 8x32, 8x8 pixels size, 

And WS2812B series led matrix, with 8x32, 16x16, 8x8 pixel 3size.
