24 Bits WS2812 RGB LED Ring SMD 5050 Addressable LED String Individual Programmable with Integrated Driver DC 5V for Arduino Raspberry Pi ESP32(Pack of 5pcs)

Description： Voltage:DC4-7V Communication interface:Single-wire communication LED Chip:WS2812B Inside Diameter: 66mm (2.59inch) Outside Diameter: 52mm (2.04inch) Connection: 5V to 5V pin 6 to DI GND to GND Package Includes: 5 X 24 Bits WS2812 RGB LED Ring FAQ Q: Can this be stripped to a red, green, and blue wire (+power) to be wired to a different board? A:No, the WS2812 is a digital LED, it need to be controlled by a micro controller or AVR (such as an Arduino or ESP8266 board) with a digital pin and appropriate library Q:Does this work with Raspberry Pi 3? A:Yes, it can. As long as you have a 5v line (which the pi 3 has) then it should work Q: Can I use raspberry pi to control the RGB led ring? A: You can use raspberry pi to control the RGB led ring, the problem is RPI is 3.3V , and RGB led ring need 5V, so you need level shifter to convert the voltage. Please check the link: https://github.com/jgarff/rpi_ws281x Q: Does each led require 18ma so the total 24 * 18 ma or total 432ma ? A: Yes, total is 24*18ma, this is for normal led brightness. You can also change code to change the led brightness, and the current will be different. Q: Is this something I can program once and not require data in? I need to program all led red or green and then power down and up to the last color. A: Yes, you can write code to achieve this function Q: I want to make a macro lens light. 1. is there a similar product which has a good cri white only output? 2. what wiring is necessary for that? A: Please check this video https://www.youtube.com/watch?v=ZGHPHuuYisw Q: What is the current draw at 5V? A: 60 mA per LED (20mA red, 20mA green, 20mA blue) 24 X .060 = 1.44 amps.

• [LED Chip] WS2812B SMD5050 RGB LED, each pixel is individually addressable and programmable
• [Work with]WS2812 RGB LED Ring, can work with ESP-01S Serial Wifi module and WS2812 RGB LED Module.
• [Input Voltage]DC4-7V, we often use USB cable to power it. If you want to use it with raspberry pi, please confirm it has 5V line, if not, then you need level shifter to convert the voltage from 3.3V to 5V
• [Current]60 mA per LED (20mA red, 20mA green, 20mA blue) 12 X 0.060 = 0.72 amps
• [How many colors can it emit?]It can emit 256X256X256=16777216 colors
• [Application]LED Ring Clock, 3D Printed LED Fire Horns, Sound Reactive Peace Pendant
