40 Bits Ring RGB LED Matrix WS2812B - 5050 LEDs

The LED lighting module consists of 40 RGB WS2812B LED diodes with an integrated driver so that each LED can have an individually set color.
The module is operated using one digital cable. Diodes consume 18mA each. Powered by 5V.
The communication protocol allows diode modules to be connected in series. Another module can be connected to the output connector. interconnecting 5V, GND, DOUT with DIN. If more than 500 LEDs are used, the RAM in the Arduino Uno may run out.

The module is ideally suited as a direction indicator for an electronic compass.

The module is compatible with the NeoPixel library.
