Matek Systems MCU CF Dual Mode RGB RC LED Light Board Strip Taillight 7 Colors 4 Status for FPV Multicopter Dual control modes:MCU Mode and CF Mode. Use them with Cleanflight or you could simply change the color with the button MCU mode: 7 colors(White, Green, Red, Blue, Yellow, Cyan, Magenta).4 status(Constant light, Slow flash, Fast flash,Voilent flash) CF mode:support CC3D, Naze32, SP Racing F3,etc.with CleanFlight firmware Each one has 18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. 8 individually addressable RGB LEDs STM MCU assembled. Each board features 8 tiny 5050 (5mm x 5mm) smart RGB LEDs. Each LED is addressable as the driver chip is inside the LED
