Matek RGB LED & Buzzer Board

Digitally Addressable LED stick with buzzer, perfect for quadcopter tail lights.

36 available




The Matek WS2812B RGB LED & Buzzer Board is a great option for a quadcopter tail light. With 6 of the tiny 5050 (5mm x 5mm) smart RGB LEDs on a PCB with mounting holes and a chainable design. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. 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. Power the whole thing with 5VDC (4-7V works) and you’re ready to rock.

The addition of a buzzer allows you to easily locate your craft, and other audible alerts from your flight controller, or any 5VDC input.

The LEDs are ‘chainable’ by connecting the output of one stick into the input of another. There is a single data line with a very timing-specific protocol. Since the protocol is very sensitive to timing, it requires a real-time microconroller such as a Betaflight (or other) Flight Controller, Arduino project, etc.

Comes as a single stick with 6 individually addressable RGB LEDs and one buzzer assembled and tested.



Dimensions 50mm x 10mm
Input Voltage 4-7VDC

Great price, fast shipping, b/c I haven't had a chance to install and fully understand the functionality of this device, this rating is new for Progressive RC for great prices and fast shipping. I'll update this product review in the very near future on my completed xhover r5x build, just no time at present (Posted on 10/26/2018)
