Questions
How big is the MoonHub PCB?
It measures 102 × 16.5 mm and has 4 copper layers, 1.56 mm thick.
What parts does the MoonHub use?
37 parts, built around the TPD4E05U06DQAR, CH334U, SMAJ5.0A and X1224WRS-04-LPV01. 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 MoonHub KiCad files?
From the certainly1182/MoonHub repository on GitHub, at the commit this page was made from: the board is MoonHub.kicad_pcb and its schematic MoonHub.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MoonHub 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).
