Questions
How big is the Moon child PCB?
It measures 31.6 × 27.7 mm and has 4 copper layers, 2.32 mm thick.
What parts does the Moon child use?
172 parts, built around the DRV8871DDARQ1, IS25LP040E-JNLE-TR, AP62250Z6 and BME280. 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 Moon child KiCad files?
From the Matthew-Bon/moon_child repository on GitHub, at the commit this page was made from: the board is moon_child.kicad_pcb and its schematic connectors_+_mechanical.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Moon child 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).
