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 image 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 lamps x 8 Voltage: 5V(4-7V) Size: 5.3 x 0.8 x 0.2cm colour: white Material: plastic Port: Digital Remark: It need to refurbish CleanFlight and use PPM 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 PPM/SBUS receiver,PWM Receiver mismatch. Only match RC Quadcopter. Options election in assistant software: PPM Receiver,then check LED_STRIP Finally into the assistant software LED Strip Page Setup states Package Include: 8 x Full-Color Driving LED Lights Board Only the above package content, other products are not included. Note: Light reflection 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.
