Revolution, Sparky2 and RevoNano boards supports external leds, up to 10 of the WS2811, WS2812 and WS2812B multi-color LEDs can be used. To use more than 10 leds you need to put the strips in parallel instead of series.
The WS281x leds do not work on CC3D/Atom boards.
WS281x Led outputs
Servo outputs (1 to 6) + FlexiIO (receiver port) pin3 and pin4
Servo outputs (1 to 6)
Servo output #1 only
External Led provides visual information about flight modes or warnings during flight/pre-flight checks.
