Description

This 37mm in diameter ring consists of 12 LED RGB WS2815 5050 with a built-in driver.

The ring are chainable between them, simply connect the output of a ring at the entrance to the next. So just one micro-controller to control a series of NeoPixel ring. Each RGB LED has of are own controller to operate independently. Each LED consumes about 18mA enn cournat constant, this allows to have a perfect color even if the voltage varies slightly.

The Ring NeoPixel works nominally 5V, but limits are between 4V and 7V.
