24 LED RGB Neopixel Rings - WS2812B
- Product SKU: NA329
- Category: Best Sellers, Components, Featured Products, LEDs and Illumination, New Products
These little LED RGB Addressable Neopixel rings are perfect for adding a pop of colour to your latest project. Each LED is super fun and glowy and you can control them all individually via your connected Microcontroller including brightness level and any RGB colour you can throw at it, that's right millions of colours at your fingertips
The sticks require 3 connections to run: A voltage source (5V), ground and a data connection from your microcontroller. You can easily chain as many of these together as you would like, each ring has an "In" data side and an "Out" data pin which you can chain from one stick to the other and have data coming in from one end
Each LED is technically capable of drawing 60mA when the LED is at 100% brightness in the colour white (Ie. 100% red, green and blue) although in normal colour sweeping modes, it is unlikely that you will ever be running the LEDs at that high of a current. A good rule of thumb when estimating an appropriate power supply is to assume a current draw of 20mA per LED. So if you have 10 LEDs. you will need a power supply capable of delivering 200mA. Having a power supply that can deliver more than the required current is never a bad thing, just make sure that it remains at 5 volts, that's important!
- Avoid connecting the LEDs to a circuit that is already on, wires should be connected and then the circuit turned on. If you must connect to a live circuit then ensure ground is connected first and then 5V second
- This type of LED requires a 5V data signal. If you are using a microcontroller with 3V logic (ESP range of controllers for instance) then you will need to use a logic level converter on the data signal
- This type of addressable LEDs required quite specific timing. Adafruit industries has put together a driver for the Arduino IDE which you can use to control the lights from your favourite microcontroller
- If you are powering your microcontroller (Arduino, ESP etc.) and your LEDs from a separate source, then you must connect the grounds of both sources together for the LEDs to operate correctly

Note: We have a guide coming soon about how to use and interface with these types of LEDs although there are a few things you should know in the meantime before getting started:
- Avoid connecting the LEDs to a circuit that is already on, wires should be connected and then the circuit turned on. If you must connect to a live circuit then ensure ground is connected first and then 5V second
- This type of LED requires a 5V data signal. If you are using a microcontroller with 3V logic (ESP range of controllers for instance) then you will need to use a logic level converter on the data signal
