Idea
This is a small PCB designed for a NodeMCU v3 to control up to 4 WS2812b LED-Strips. The goal of the project is to light up hacker jeopardy buttons or to light something with the ws2812b buttons.
Considerations:
- care has been taken that at least 2 strips are usable for Lua or Micropython respectively
- There is a jumper to bypass the voltage regulator if the board is directly supplied with 5V

Questions
How big is the Button PCB PCB?
It measures 50 × 54 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Button PCB use?
32 parts, built around the AZ1117CD and FDS4435BZ. 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 Button PCB KiCad files?
From the fox918/button-proj-hw repository on GitHub, at the commit this page was made from: the board is Button-PCB.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Button PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask fox918 before reusing the design.
