Overview
Snowflake is an open-source printed circuit board by aaknitt, from the aaknitt/Snowflakes repository on GitHub. It is a 2-layer board of 150.6 × 144.1 mm with 58 parts on 44 nets, routed with 709 tracks and 183 vias.
It is built around the ESP-12E. Its parts include 26 capacitors, 25 diodes, 2 resistors, 2 connectors and 1 IC. It belongs with the lEDs and displays boards and the ESP8266 boards of this library.

KiCAD and FreeCAD files for RGB(W) snowflakes
KiCAD schematic and PCB layout files (along with associated Gerber files) for ESP8266-based RGB(W) snowflakes.
FreeCAD files for 3D printed diffuser (use clear filament).
Each snowflake uses 25 SK6812 (for RGBW) or WS2812b pixels. Can be operated using the fantastic ESPixelStick firmware in conjunction with a program such as XLights64.
Unmodified ESPixelStick firmware should work with RBG pixels.
If using RGBW pixels, modified firmware is necessary (I may put up a fork at some point in the future).
Note: I have not actually made a batch of PCBs from these exact files. I built PCBs using an earlier version, and these files include all of the changes I've made to correct mistakes in the original batch. Use at your own risk!

Questions
How big is the Snowflake PCB?
It measures 150.6 × 144.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Snowflake use?
58 parts, built around the ESP-12E. 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 Snowflake KiCad files?
From the aaknitt/Snowflakes repository on GitHub, at the commit this page was made from: the board is KiCAD/Snowflake.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Snowflake design in my own project?
Its repository states no licence, so its author keeps all rights: ask aaknitt before reusing the design.
