16 LED Ring WS2812B RGB addressable, 68mm

The 16 LED Ring with 16 x fully addressable RGB LEDs WS2812B in the big 5050 SMD package (5×5 mm). 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: 54mm
Diameter outside: 68mm

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.
