There is other WS2812B WS2812 sk6812 2020 RGB Neo Pixel LED Ring 30 60 100 120 pixels optional
Led Quantities: 30LED/60LED/100LED/120LED=310pcs (4pcs rings )
Based on sk6812 2020 RGB LEDs
sk6812 led based NeoPixel ring modules contain 310 pcs 5050 RGB LEDs on tiny circular PCBs.
There are a total of 4 PCB rings setup as follows:
1 Ring with 30 sk6812 LEDs (40mm outer diameter)
1 Ring with 60 sk6812 LEDs (80mm outer diameter)
1 Ring with 100 sk6812 LEDs (140mm outer diameter)
1 Ring with 120 sk6812 LEDs (160mm outer diameter)
We have a page dedicated to the setup, connection, and software necessary to drive a NeoPixel Ring set directly from an Arduino ATTiny85.
There are four connections to each ring.
VCC: Power input (4v to 7v DC)
GND: Common Ground connection for signal and power
IN: Input signal from your control processor
OUT: Output to chain to next module
Each ring can operate on their own or connect in a string.
Uses 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.
1. DC5V Working Voltage. Inlcuding 30led/60led/ 100led/120led.
the Power is 6W /12W /20W /24W .
2.IC Chip: sk6812ic inside.RGBW Color. can control By bloothtooth controller or SD card controller.get Flashing effect.
3.Round shape with 3Pin connector.install easily.
4.INDIVIDUAL ADDRESSABLE: Each LED is addressable as the driver chip is inside the LED. So each pixel can have its own color and brightness as your wish.
5.COLORFUL:256 brightness display and full 24-bit color display. Each LED can have its own color and brightness. You can control each LED individually and set it to any color or animation you want.
6.PROGRAMMABLE:Works great with Raspberry Pi or Arduino or T-1000S controller and is easy to program. Can appear colorful lighting effect with sk6812 controller.
7.IDEAL for DIY : Amazing led ring, you can use this to DIY whatever you can imagine.
1. decotative lights, back lights, cabinet lights, edge light, architectural lights for corridor, canopy, archway, lights for path and contour marking; etc. They can be a good choice for lights for hotels, restaurants, night clubs, coffee / wine bars, shopping malls, various shops, cinemas, beauty centers, office fronts, even lights for household kitchens or living rooms, etc.
Specification of 4 pcs rings
Double outlet-100mm,use the screw to installation.
