WS2812B is the second generation with the built-in IC and 5050RGB lamp bead type with four feet.WS2812B's feet are less than WS2812 with 6 and the circuit is more conciseIt. It can be used for Naze32, CC3D flight control and can show the flight control lock / unlock, left aileron, brake, throttle, alarm and other status.Platform: AVR, for ,Naze32/CC3D Flight Control(Refurbish to be CleanFlight)5050 Highlight LED,Built-in control chip.It can control one or more LED with just only one IO port.Signal can Stable display and not cumulate in distortion with the Chip built-in circuit.Three primary level 256 can adjust brightness.160000 color display the effect.Not less than 400 HZ/S scanning frequency.Serial interface level can complete the data through a signal receiving and decoding.Highlight LED, high light color brightness uniformity.There are interfaces at both ends(DIN DOUT).They can be concatenated.LED: 5050 Package RGB full color highlighting WS2812B *8Voltage: 5V(4-7V)Size: 5.3*0.8*0.2cmcolour: whiteMaterial: plastic Port: Digital Remark: It need to refurbish CleanFlight and use receivers when used in Naze32 or CC3D flight control.CleanFlight supports up to four lights, namely 32 WS2812B lamp beads.CC3W need Refurbish to be CleanFlight.Use /SBUS receiver,PWM Receiver mismatch.Only match RC Quadcopter. election in CF assistant software: Receiver,then check LED_STRIP Finally into the CF assistant software Page Setup statesPackage Include: 1 x Full-Color Driving LED Lights BoardOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
