Questions
How big is the Momo PCB?
It measures 228.1 × 85.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Momo use?
215 parts, built around the WS2812B. 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 Momo KiCad files?
From the calebe94/momo-pcb repository on GitHub, at the commit this page was made from: the board is momo.kicad_pcb and its schematic backlight.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Momo design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
