SKU: BU0317Overview:
What is better than smart RGB LEDs? Smart RGB+White LEDs! These sticks now have 4 LEDs in them (red, green, blue and white) for excellent lighting effects. These are fun and glowy, and you can control each LED individually! Make your own little LED arrangement with this stick of this LED.
Features:
This is the Natural White RGBW version.
The LED is 'split', one half is the RGB you know and love, the other half is a white LED with a yellow phosphor. Unlit, it resembles an egg yolk. Lit up these are insanely bright (like ow my eye hurts) and can be controlled with 8-bit PWM per channel (8 x 4 channels = 32-bit color overall). Great for adding lots of colorful + white dots to your project!
We crammed 8 of the tiny 5050 (5mm x 5mm) smart RGBW LEDs onto 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.
LEDs use 800 KHz protocol so specific timing is required. The PWM rate is ~400 Hz, which works well but is noticable if the LED is moving.
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 microcontroller 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. As it requires hand-tuned assembly it is only for AVR cores but others may have ported this chip driver code so please google around. An 8MHz or faster processor is required.
Note: The color of item might be slightly different from the picture shown, which mainly lies in different light effect and computer monitor. Please give us your understanding. Thank you!
