Overview
Liquidpixel is an open-source printed circuit board by BUILDS-, from the BUILDS-/liquidpixel repository on GitHub. It is a 2-layer board of 17.8 × 11.4 mm with 6 parts on 4 nets, routed with 49 tracks and 2 vias.
It is built around the WS2812. Its parts include 2 connectors, 1 capacitor and 1 IC.

Rev. A Logs
- After looking over the Neopixel design with its resistors to prevent the inputs, outputs and VDD for the control unit from getting fried I believe that this is a common problem and the next revision will have the appropriate resistor and capacitors.
- 4 proven working, 5 broked... Not 100% sure why, doesn't seem to be a soldering issue. I could have hooked them up wrong somehow during testing, but this should only apply to 1 or 2.
- Holes for .1" spaced headers are a little small, widen for future revisions.

Questions
How big is the Liquidpixel PCB?
It measures 17.8 × 11.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Liquidpixel use?
6 parts, built around the WS2812. 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 Liquidpixel KiCad files?
From the BUILDS-/liquidpixel repository on GitHub, at the commit this page was made from: the board is hardware/liquidpixel.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Liquidpixel design in my own project?
Its repository states no licence, so its author keeps all rights: ask BUILDS- before reusing the design.
