They keep getting rounder and rounder! 16 ultra-bright, intelligent LED NeoPixels are arranged in a circle with an outer diameter of 44.5 mm. The rings are chainable - connect the output pin of one to the input pin of another. Use just one microcontroller pin to control as many as possible. Each LED is addressable since the driver chip is integrated within the LED. Each has a constant current drive of about 18 mA, ensuring that the color remains very consistent even when the voltage varies. No external current-limiting resistors are required, making the design sleek. Power is supplied with 5 VDC (4-7 V works) and you are ready to rock.

There is a single data line with a very time-dependent protocol. Since the protocol is time-dependent, it requires a real-time microcontroller like AVR, Arduino, PIC, mbed, etc. It cannot be used or interpreted with a Linux-based microcomputer. Microcontrollers like the Netduino or Basic Stamp are not compatible. Our wonderfully written NeoPixel library for Arduino supports the functions of addressable pixels. As it requires manually tuned assembly, it is only suitable for AVR cores, but others may have ported this chip driver code, so please do your research. A processor with 8 MHz or faster is required.

It is supplied as a single ring with 16 individually addressable RGB LEDs, mounted and tested.

Dimensions: 44.5 mm outer diameter, 31.75 mm inner diameter, 25 mm thick. Weight: 3.03 g.
