Questions
How big is the ProjectMoleson PCB?
It measures 150 × 52 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ProjectMoleson use?
139 parts, built around the MCP73831T-2ACI/OT-HXY, APA102-2020, 12401598E4#2A and MBR120. 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 ProjectMoleson KiCad files?
From the RafaelRiber/ProjectMoleson repository on GitHub, at the commit this page was made from: the board is ProjectMoleson.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ProjectMoleson 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).
