## Description
14mm Fibonacci48 is a tiny, beautiful 14mm circular disc with 48 1mm WS2812B RGB LEDs surface mounted in a Fibonacci distribution.
It consists of 48 XINGLIGHT XL-1010RGBC-WS2812B 1mm addresssable RGB LEDs, arranged into a circular [Fermat's spiral](https://en.wikipedia.org/wiki/Fermat%27s_spiral) pattern.
I have created several LED art pieces in Fibonacci patterns. They are all very labor intensive to create, and so are fairly expensive and limited in quantity. I wanted to come up with a Fibonacci layout that was at least slightly easier to create, and therefore more affordable.
I have RGB LEDs in just about every form they come: strips, strings, rings, discs, etc. The LEDs on most discs are arranged in very regular rings. 14mm Fibonacci48 is different. The LEDs are arranged in a Fibonacci distribution. The makes the layout very organic and seemingly messy. But with the proper animation, spiral patterns emerge with spectacular results.
The XINGLIGHT XL-1010RGBC-WS2812B each only consume a maximum of 15mA, and that's at 100% brightness, solid white color. That's only 720mA for all 48 combined. They are still very bright, and I usually only run them at about 25% brightness. They're perfect for wearables, powered with LiPo batteries.
It has solder pads on the back that match the pinout of the [TinyLily](https://tinycircuits.com/products/tinylily-mini-processor), although WARNING: I've had a hard time driving them with TinyLily when powered via small LIR coin cell batteries. The LEDs glitch at the upper-range of the batteries' voltage, but work fine at the lower end, or with a resistor inline with the power to drop the voltage.
It can be used with any microcontroller via the 5V, GND, and Data In pads. It also has a Data Out pad, for connecting more LEDs on the same data pin.
