More info

Include a Buzzer in your LED strip arrangement. 6 tiny 5050 (5mm x 5mm) smart RGB LEDs on one PCB with mounting holes and a chainable design. Use only one microcontroller pin to control all the LEDs chained 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 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 an AVR, Arduino, PIC, mbed, etc. It cannot be used with a Linux-based microcomputer or interpreted microcontroller such as the netduino or Basic Stamp. An 8MHz or faster processor is required.
