# NeoPixel Ring - 16 x WS2812 5050 RGB LED with Integrated Drivers

**Type:** Product page · **SKU:** ADA1463 · **Brand:** [Adafruit](https://core-electronics.com.au/brands/adafruit-australia)
**Page:** https://core-electronics.com.au/neopixel-ring-16-x-ws2812-5050-rgb-led-with-integrated-drivers.html ([markdown](https://core-electronics.com.au/neopixel-ring-16-x-ws2812-5050-rgb-led-with-integrated-drivers.html.md))

Round and round and round they go! 16 ultra bright smart LED NeoPixels are arranged in a circle with 1.75" (44.5mm) outer diameter. The rings are 'chainable' - connect the output pin of one to the input pin of another.

## Pricing

- **Price:** $17.50 (inc GST) — $15.91 AUD, exc GST
- **Quantity discounts:** 10+ $15.44 (exc GST) · 50+ $15.11 (exc GST)

## Availability & dispatch

- In stock, ships same business day if ordered before 2PM (Australia/Sydney).
- We can dispatch 5 today, and up to 500 more in 8–12 days.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA1463:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/ADA1463:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

Round and round and round they go! 16 ultra bright smart LED NeoPixels are arranged in a circle with 1.75" (44.5mm) outer diameter. 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 ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC (4-7V works) and you're ready to rock. 

There is a single data line with a very timing-specific protocol. Since the protocol is very sensitive to timing, it requires a real-time microconroller such as an AVR, Arduino, PIC, mbed, etc. It cannot be used with a Linux-based microcomputer or interpreted microcontroller such as the netduino or Basic Stamp. Adafruit's wonderfully-written [Neopixel library for Arduino supports these pixels!](https://github.com/adafruit/Adafruit_NeoPixel) As it requires hand-tuned assembly it is only for AVR cores but others may have ported this chip driver code so please google around. An 8MHz or faster processor is required. 

Comes as a single ring with 16 individually addressable RGB LEDs assembled and tested. You will need to solder on your own connectors, either [header pins](https://core-electronics.com.au/male-pin-header-2-54mm-1x40.html), or [hookup wires](https://core-electronics.com.au/silicone-hookup-wire-kit-6-colours-stranded.html) work best.
