Overview
WS2812S ATtiny45 is an open-source printed circuit board by icchalmers, from the icchalmers/WS2812S_ATtiny45 repository on GitHub. It is a 2-layer board of 38.2 × 14.2 mm with 6 parts on 11 nets, routed with 79 tracks and 0 vias.
Its parts include 2 ICs, 1 capacitor, 1 resistor, 1 connector and 1 switch. It belongs with the lEDs and displays boards and the AVR (ATmega, ATtiny) boards of this library.
README
README.mdWS2812S with ATtiny85
This is a small test board for the WS2812S LEDs using the ATtiny85. It was made as part Fab Academy 2015 at Fab Lab Strathclyde. You can follow the process on my class website. The content is also mirrored to my GitHub Pages site.
Design
The board was designed in KiCad, and machined on a Denford PCB Engraver. The footprints are designed for reflow soldering, but the board should be hand solderable with a steady hand.
All of the parts are part of the standard Fab Lab inventory, with the exception of the WS2812S and the ATtiny85. However, you can substitute an ATtiny45 without any problem. I just used an 85 because a) more memory and b) we actually got them cheaper!

Questions
How big is the WS2812S ATtiny45 PCB?
It measures 38.2 × 14.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the WS2812S ATtiny45 use?
6 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the WS2812S ATtiny45 KiCad files?
From the icchalmers/WS2812S_ATtiny45 repository on GitHub, at the commit this page was made from: the board is WS2812S_ATtiny45.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the WS2812S ATtiny45 design in my own project?
Its repository states no licence, so its author keeps all rights: ask icchalmers before reusing the design.
