12 x WS2812B RGB LED Ring, fully addressable, 50mm

Description

• 12 RGB LED Ring fully addressable WS2812B 4-7V
• 12 LEDs 5050 full color RGB with integrated driver
• Every LED individual addressable through protocol.
• 1-wire interface to Microcontroller.

A ring with 12 fully addressable RGB LEDs WS2812B in the big 5050 SMD package (55 mm), fully controllable by a single wire serial connection from a microcontroller.
This module is compatible with Adafruit Industries NeoPixel library for Arduino.
The modules have mounting holes and can be cascaded to build bigger arrangements.
Diameter inside: 36mm
Diameter outside: 50mm
Every LED contains its own 18mA constant-current driver, and an addressable driver chip, and will work without any current limiting resistors on a power supply of 4-7V.
Since the data protocol is quite timing-specific, you will need a faster microcontroller (at least 8MHz) to control it. You can use it for example with an AVR and Arduino, PIC, STM32 or similar controller. You will have no luck with interpreted controllers like Basic Stamp or Picaxe.
Neopixel Library for Arduino download
WS2812B datasheet download
Adafruit registered the brand name Neopixel for these LEDs. But the manufacturer is Worldsemi and not Adafruit. Dont get fooled and believe this would be developed by Adafruit. Adafruit only created a library for Arduino.
We have single WS2812B LEDs and different ring or matrix modules (8 LEDs, 16 LEDs, 64 LEDs), compatible with the Neopixel library for Arduino, in stock.
