This disk is chock full of 255 Dotstar LEDs and it's Bright. The Dotstar RGB LED Disk is sprinkled with digitally-addressable LEDs, comes on a white PCB with two 4 pin JST-SM connectors already soldered to.
The LEDs included in this disk have a size og 5x5mm and use a protocol of comunication 2-wire that is less timing-specific and has high-frequency PWM for smoother color blending.
Like NeoPixels, DotStar LEDs are 5050-sized LEDs 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 infinite number of LEDs. The PWM is built into each LED-chip so once you set the color you can stop talking to the disk and it will continue to PWM all the LEDs for you
DotStars have a 20 KHz PWM rate, so even when moving the disk around, you won't see the pixelation, the color blending is very smooth.
Note: You'll need a lot of power to fully light up this disk, so be sure to pick of a 5V 10A power supply!
