Our biggest LED ring yet!

With this set of four segments, you can make a huge ring with 60 ultra bright smart RGBs are arranged in a circle with a 78.74mm diameter.

You are receiving four individual quarter rings. All four of this item are required to make a large ring. You will have to solder them together as well!

Each individual segment and the ring as a whole are 'chainable'.

For the whole ring - or multiple rings - connect the output pin of one to the input pin of another.

You can use a single microcontroller pin to control as many as you can chain together! With the driver chip being inside of each LED, each LED is individually addressable. Each LED has ~18mA constant current drive resulting in the colour to be very consistent even if the voltage varies.

The slim design is achieved by not using external choke resistors.

Power requirement the whole thing with 5VDC.

A single data line is supported by a very timing-specific protocol and 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. The awesome Adafruit Neopixel library for Arduino can be used with these LED rings. 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.
