NeoPixel Ring 16 x 5050 RGB LED with Integrated Drivers

NeoPixel Ring 16 x 5050 RGB LED with Integrated Drivers - Round and round and round they go! 16 ultra bright smart LED NeoPixels are arranged in a circle with 1.75" (44.5mm) outer diameter. The rings are 'chainable' - connect the output pin of one to the input pin of another. 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.

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. Our wonderfully-written Neopixel library for Arduino supports these pixels! 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.

Comes as a single ring with 16 individually addressable RGB LEDs assembled and tested.

Q6: What are some tips for using a NeoPixel Ring 16 x 5050 RGB LED with Integrated Drivers?

• Be careful not to exceed the maximum current rating of the LED ring.
• Connect the ring to a stable power source to prevent voltage fluctuations that can damage the LEDs.
• Use a logic level shifter if the microcontroller is running at a different voltage than the LED ring.
• Avoid bending or flexing the ring, as this can damage the LEDs or the connections between them.
• Always use a resistor in series with the data line to protect the LEDs and the microcontroller from voltage spikes or other electrical noise.
