12 LED Ring WS2812B RGB addressable, 50mm

The 12 LED Ring with 12 fully addressable WS2812B chips in the big 5050 SMD package (5×5 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.
