24x 5050 ultra bright LED, comes with an embedded microcontroller inside the LED
The rings are 'chainable': connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together!
Each LED is addressable as the driver chip is inside the LED.
Each one has about 18mA constant current drive so the color will be very consistent even if the voltage varies, and no need external choke resistors.
Use 800 KHz protocol so specific timing is required.
This board is 'split', one half is the RGB you know and love, the other half is a white LED with a yellow phosphor.
Controlled with 8-bit PWM per channel (8 x 4 channels = 32-bit color overall).
You can set the brightness and color of each R/G/B/W with 8-bit PWM precision (so 32-bit color per pixel). The LEDs are controlled by shift-registers and only 1 digital output pin are required to send data down. The PWM is built into each LED-chip so once you set the color you can stop talking to the ring and it will continue to PWM all the LEDs for you.
Power: 5V DC
PWM rate: about 400Hz
Outer diameter: 65.5mm / 2.58"
Inner diameter: 52.2mm / 2.05"
Thickness: 3.25mm / 0.13"
May ship with either WS2812B or SK6812-based LEDs. They are the same brightness, color and protocol
